As established in #5975, this is intended behavior: applying an affine-dependent transform such as `Spacing`/`Spacingd` after `Transpose`/`Transposed` can therefore produce unexpected results. The note points users to `Orientation`/`Orientationd` for affine-aware reorientation. This is a documentation-only change; no functional code is modified. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [ ] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [x] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder.

Adds a `_spatial_ndim: int` attribute to `MetaTensor` that explicitly tracks the number of spatial dimensions, preventing dimension-mismatch crashes when `einops.rearrange()` or other reshape operations change `ndim` - The attribute propagates through `copy_meta_from` (via `__dict__` copy) and is preserved through arbitrary torch operations - Updates transforms (`Resize`, `Rotate`, `Zoom`, `Flip`, `Affine`, `SplitDim`, `AddCoordinateChannels`, etc.) and lazy resampling to use `spatial_ndim` instead of hardcoded 3 ### Key design decisions - **Constructor**: `spatial_ndim = min(affine.shape[-1] - 1, ndim - 1)` — clamped by actual tensor dims - **Affine setter**: `spatial_ndim = affine.shape[-1] - 1` — no clamping (user is explicit) - **`peek_pending_affine`**: uses affine's inner matrix shape (fixes batched `(1,4,4)` case) - **`spatial_resample`**: `min(spatial_ndim, ndim - 1, 3)` — adds ndim-1 constraint as safety net ### Files changed (16) - `monai/data/meta_obj.py`, `meta_tensor.py`, `utils.py`, `__init__.py` — core MetaTensor changes - `monai/transforms/` — spatial, croppad, intensity, inverse, lazy, post, utility transforms updated - `tests/data/meta_tensor/test_spatial_ndim.py` — 18 new tests - Existing test files updated with `spatial_ndim` assertions ## Test plan - [x] 18 new unit tests for `spatial_ndim` property (construction, affine sync, propagation, einops reshape, transforms) - [x] Existing MetaTensor tests pass (162 tests) - [x] SqueezeDim and SplitDim tests pass with new assertions -

charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary - Rebase Docker image from `nvcr.io/nvidia/pytorch:24.10-py3` to `25.03-py3` to support RTX 5090 (Blackwell, SM_120/CUDA 12.8); remove the now-obsolete `torch.patch` ONNX revert which was specific to 24.10 - Pin `mlflow<3.0` — mlflow 3.x is broken on Python 3.12 due to a relative import in `mlflow.utils.uv_utils` (`from .. import zipp` fails at top-level scope); this caused 4 tutorial notebooks to fail in our CI run - Pin `transformers<5.0` — transformers 5.x references `torch.float8_e8m0fnu` which does not exist in the nv25.03 build of PyTorch 2.7; this caused the HuggingFace tutorial to fail - Add `aim` and `lightning>=2.0` as declared dependencies in `requirements-dev.txt` (were previously undeclared but required by tutorial notebooks) - Rebuild the NVIDIA pip constraint file to retain `numpy==1.26.4` (nv25.03 PyTorch compiled against NumPy 1.x) and add `setuptools<71` (newer setuptools dropped `pkg_resources` needed by legacy `setup.py` in git-sourced packages like MetricsReloaded and segment-anything) - Remove `python_version <= '3.10'` caps from `cucim`, `onnxruntime`, and `transformers` — these restrictions were keeping packages out of the Python 3.12 image unnecessarily - Install `papermill`, `jupytext`, `autopep8`, `autoflake`, and `ipywidgets` directly in the Dockerfile so the tutorial runner is self-contained ## Context These changes were identified by running the full MONAI tutorial test suite in a fresh Docker build against a MONAI 1.6 dev branch and comparing results with a native conda reference run (Eric's run, `eccefc57`). The rerun with stderr captured (`runner_output_our_only.logs`) confirmed the specific error for each notebook group. ## Type of change - [x] Bug fix - [ ] Feature - [ ] Hotfix - [ ] Spike / exploration - [ ] Documentation - [ ] Refactor ## Test plan - [ ] Rebuild Docker image with `docker build -t monai_1_6:latest .` - [ ] Re-run `bash run_our_only.sh 2>&1 | tee runner_output_v2.logs` inside the container - [ ] Verify mlflow notebooks pass (R1: 4 notebooks) - [ ] Verify `hugging_face/hugging_face_pipeline_for_monai.ipynb` passes (R3) - [ ] Verify `experiment_management/spleen_segmentation_aim.ipynb` passes (R6) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: R.

When both `tprec` and `tsens` are zero (e.g., empty inputs, non-overlapping predictions/targets, or `smooth=0`), this results in `0/0 = NaN`, which propagates through the loss and crashes training. While the default `smooth=1.0` prevents `tprec` and `tsens` from being exactly zero in most cases, setting `smooth=0` (a valid configuration) exposes this bug whenever skeleton overlap is zero. The fix adds `1e-7` to the harmonic mean denominator, which: - Has negligible impact on normal computation (tprec, tsens are bounded in [0, 1]) - Returns `cl_dice = 1.0` (maximum loss) when both precision and sensitivity are zero, which is the correct semantic result - Is consistent with epsilon-based denominator guards used elsewhere in MONAI (e.g., `smooth_dr` in `DiceLoss`) ## Test plan - [x] Existing `test_cldice_loss.py` tests still pass (perfect overlap cases) - [x] New `test_zero_input_no_nan`: verifies zero-valued inputs with `smooth=0` do not produce NaN - [x] New `test_no_overlap_no_nan`: verifies non-overlapping predictions/targets with `smooth=0` do not produce NaN --- monai/losses/cldice.py | 3 ++- tests/losses/test_cldice_loss.py | 46 ++++++++++++++++++++++++++++++++ 2 files changed, 48 insertions(+), 1 deletion(-) diff --git a/monai/losses/cldice.py b/monai/losses/cldice.py index 7d7e447c54..60e8601459 100644 --- a/monai/losses/cldice.py +++ b/monai/losses/cldice.py @@ -134,7 +134,8 @@ def __init__( Args: iter_: Number of iterations for skeletonization.

Since `offsets` is a torch tensor derived from `boxes_t`, passing an ndarray added a numpy array to a torch tensor and raised `TypeError`, breaking `batched_nms` for all ndarray inputs. The offset is now added to the converted tensor: `boxes_for_nms = boxes_t + offsets[:, None]`. Everything else downstream already operates on `boxes_t`, and the result is converted back to the input type, so the torch path is unchanged. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. --------- Signed-off-by: Soumya Snigdha Kundu Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/data/box_utils.py | 2 +- tests/data/test_box_utils.py | 11 +++++++++++ 2 files changed, 12 insertions(+), 1 deletion(-) diff --git a/monai/data/box_utils.py b/monai/data/box_utils.py index b0c41b5d7d..2f4a1426a9 100644 --- a/monai/data/box_utils.py +++ b/monai/data/box_utils.py @@ -1200,7 +1200,7 @@ def batched_nms( # from different classes do not overlap max_coordinate = boxes_t.max() offsets = labels_t.to(boxes_t) * (max_coordinate + 1) - boxes_for_nms = boxes + offsets[:, None] + boxes_for_nms = boxes_t + offsets[:, None] keep = non_max_suppression(boxes_for_nms, scores_t, nms_thresh, max_proposals, box_overlap_metric) # convert tensor back to numpy if needed diff --git a/tests/data/test_box_utils.py b/tests/data/test_box_utils.py index 05778f691b..30136d4f1b 100644 --- a/tests/data/test_box_utils.py +++ b/tests/data/test_box_utils.py @@ -23,6 +23,7 @@ CornerCornerModeTypeB, CornerCornerModeTypeC, CornerSizeMode, + batched_nms, box_area, box_centers, box_giou, @@ -269,5 +270,15 @@ def test_integer_truncation_bug(self): self.assertGreater(iou[0, 0], 0.0, "IoU should not be truncated to 0") +class TestBatchedNms(unittest.TestCase): + @parameterized.expand(TEST_NDARRAYS) + def test_batched_nms_backend(self, p): + boxes = p(np.array([[0, 0, 10, 10], [1, 1, 11, 11], [100, 100, 110, 110]], dtype=np.float32)) + scores = p(np.array([0.9, 0.8, 0.7], dtype=np.float32)) + labels = p(np.array([0, 0, 1])) + keep = batched_nms(boxes, scores, labels, nms_thresh=0.5) + assert_allclose(keep, [0, 2], type_test=False) + + if __name__ == "__main__": unittest.main() From 2dbbd49329e51e58bd25b32f68c945d2c7edf608 Mon Sep 17 00:00:00 2001 From: Raphael Malikian Date: Thu, 25 Jun 2026 09:53:36 -0700 Subject: [PATCH 13/72] fix: add missing stacklevel=2 to warnings.warn() in metrics/ (Fixes #8931) (#8932) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #8931 ## Problem 12 `warnings.warn()` calls in `monai/metrics/` are missing `stacklevel=2`. Without this parameter, warnings point to MONAI library internals instead of the user's calling code, making them unhelpful for debugging. This follows the same pattern identified in `losses/` (PR #8930) and is a natural extension to the `metrics/` module. ## Solution Added `stacklevel=2` to all 12 `warnings.warn()` calls across 6 files in `monai/metrics/`: | File | Warning | Line | |------|---------|------| | `cumulative_average.py` | non-finite inputs received | ~157 | | `average_precision.py` | y values all same / invalid | ~91, ~96 | | `utils.py` | ground truth/prediction all zero | ~342, ~348 | | `utils.py` | binarized tensor | ~380 | | `utils.py` | Voronoi CPU | ~515 | | `active_learning_metrics.py` | spatial map / reduction | ~140, ~195 | | `confusion_matrix.py` | compute_sample | ~96 | | `rocauc.py` | y values all same / invalid | ~80, ~85 | Note: `embedding_collapse.py` already had `stacklevel=3` (intentionally different for its call depth) and was left unchanged. ## Verification - All 6 modified files pass `ast.parse()` syntax check - All 14 `warnings.warn()` calls in `monai/metrics/` confirmed to have `stacklevel` parameter - No other code changes — purely additive `stacklevel=2` parameter additions ## Changelog | Date | Change | Author | |------|--------|--------| | 2026-06-19 | Add missing stacklevel=2 to 12 warnings.warn() calls in monai/metrics/ | rtmalikian | ### Files Changed - `monai/metrics/cumulative_average.py` — Added stacklevel=2 to 1 warning - `monai/metrics/average_precision.py` — Added stacklevel=2 to 2 warnings - `monai/metrics/utils.py` — Added stacklevel=2 to 4 warnings - `monai/metrics/active_learning_metrics.py` — Added stacklevel=2 to 2 warnings - `monai/metrics/confusion_matrix.py` — Added stacklevel=2 to 1 warning - `monai/metrics/rocauc.py` — Added stacklevel=2 to 2 warnings ### Verification - All 6 files pass Python syntax check (ast.parse) - All 14 warnings.warn() calls in monai/metrics/ confirmed to have stacklevel parameter - No functional behavior changes — only warning source location improves --- **About the Author:** Raphael Malikian — Clinical AI Solutions Architect.

Without `stacklevel=2`, warnings point to the MONAI internal code instead of the user's calling code, making it difficult for users to identify which part of their script triggered the warning. ## Solution Added `stacklevel=2` to all 28 `warnings.warn()` calls across 9 loss modules: - `dice.py` (7 instances) - `tversky.py` (3 instances) - `mcc_loss.py` (3 instances) - `focal_loss.py` (3 instances) - `hausdorff_loss.py` (3 instances) - `unified_focal_loss.py` (3 instances) - `spatial_mask.py` (3 instances) - `perceptual.py` (2 instances) - `adversarial_loss.py` (1 instance) Also fixes a typo in `perceptual.py`: `"supp, ort"` → `"support"` (carried from #8924). ## Verification ```bash # All 28 warnings.warn() calls now have stacklevel=2 $ grep -c "stacklevel" monai/losses/*.py # Each file's stacklevel count matches its warnings.warn count # All 9 files pass syntax check $ python3 -c "import ast; [ast.parse(open(f).read()) for f in files]" 9 files checked, 0 errors ``` ## Changelog | Date | Change | Author | |------|--------|--------| | 2026-06-19 | Add missing stacklevel=2 to 28 warnings.warn() calls in 9 loss modules | rtmalikian | ### Files Changed - `monai/losses/dice.py` — 7 warnings.warn() calls updated - `monai/losses/tversky.py` — 3 calls updated - `monai/losses/mcc_loss.py` — 3 calls updated - `monai/losses/focal_loss.py` — 3 calls updated - `monai/losses/hausdorff_loss.py` — 3 calls updated - `monai/losses/unified_focal_loss.py` — 3 calls updated - `monai/losses/spatial_mask.py` — 3 calls updated - `monai/losses/perceptual.py` — 2 calls updated + typo fix - `monai/losses/adversarial_loss.py` — 1 call updated ### Verification - All 28 warnings.warn() calls now include stacklevel=2 - All 9 modified files pass Python syntax validation - No duplicate stacklevel parameters --- **About the Author:** Raphael Malikian — Clinical AI Solutions Architect.

That stencil is less accurate than the standard compact one and forced the validation "all spatial dims > 4". This PR replaces the second-order computation with compact central stencils evaluated directly on `pred`: - **Pure** ``d^2/dx_i^2``: ``x[i+1] - 2 * x[i] + x[i-1]`` (the standard `[1, -2, 1]` kernel). - **Mixed** ``d^2/(dx_i dx_j)``: ``(x[i+1,j+1] - x[i+1,j-1] - x[i-1,j+1] + x[i-1,j-1]) / 4`` (compact 4-point central scheme). Both span three voxels per axis, so the spatial-size validation is relaxed from `> 4` to `> 2`, matching `DiffusionLoss`. The public API (`__init__(normalize, reduction)`, `forward(pred)`) and `normalize` semantics are unchanged. The existing `spatial_gradient` helper is left untouched because `DiffusionLoss` still uses it. ### Why TEST_CASES expected values do not change For ``f(x) = x^2``, the analytical second derivative is the constant `2`. Both the previous central-of-central stencil ``(f[i+2] - 2*f[i] + f[i-2]) / 4`` and the new compact ``[1, -2, 1]`` stencil ``f[i+1] - 2*f[i] + f[i-1]`` are exact for quadratics, so both return `2` at every interior voxel. Mixed-partial test inputs are constant in at least one of the two axes, so both stencils return `0` for mixed terms on these cases. Squared and reduced by ``mean``, the existing `TEST_CASES` expected values (``0.0``, ``4.0``, ``100.0``) are therefore invariant under this change. What does change in the tests: - `test_ill_shape` is updated to trigger on shape `2` (was `4`) so it still exercises the spatial-size guard. - A new `TEST_CASES` row covers shape `(1, 3, 3, 3, 3)` of ones (previously rejected by the `> 4` guard) → expected `0.0`, validating the relaxed guard.

Investigation: - Every direct `reader.read(...)` call site in ``tests/utils/enums/test_wsireader.py`` already either uses ``with reader.read(...) as obj:`` or explicitly calls ``obj.close()`` on the returned WSI object. Those sites are not the leak. - The remaining leak comes from ``LoadImage.__call__`` in ``monai/transforms/io/array.py`` (around L256–289), which does: ```python img = reader.read(filename) img_array, meta_data = reader.get_data(img) # ... img_array is wrapped into MetaTensor and returned # the reader-returned `img` is never closed ``` The two ``test_with_dataloader*`` tests in this module use ``LoadImaged(reader=WSIReader, backend=..., ...)`` and inherit that leak. The temp TIFF handles only get closed when the garbage collector eventually runs, frequently after Python has already emitted the warning. This PR keeps the fix at test-hygiene scope: add ``gc.collect()`` to ``tearDown`` of the shared ``WSIReaderTests.Tests`` base class. Each of ``TiffFile.__del__`` / ``OpenSlide.__del__`` / ``CuImage.__del__`` closes the underlying file descriptor, so running gc explicitly at the end of every test invokes those finalizers deterministically and eliminates the warning. ### Why not change ``LoadImage`` / ``BaseWSIReader`` A reader-level or ``LoadImage``-level fix is feasible (e.g. closing ``img`` after ``get_data`` returns) but is broader in scope, affects all readers, and would need to land alongside changes to the public contract of ``BaseWSIReader.read`` (currently documented to return an open WSI object). Happy to follow up with that if a maintainer prefers; this PR was scoped narrowly to the test symptom that the issue raises. ### Verify ```bash python -m pytest tests/utils/enums/test_wsireader.py -W error::ResourceWarning -v ``` Expected: tests pass and no ``ResourceWarning`` escalations. --------- Signed-off-by: Vishnu Kannaujia Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- tests/utils/enums/test_wsireader.py | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/tests/utils/enums/test_wsireader.py b/tests/utils/enums/test_wsireader.py index 2c6498234e..ee6462b579 100644 --- a/tests/utils/enums/test_wsireader.py +++ b/tests/utils/enums/test_wsireader.py @@ -11,6 +11,7 @@ from __future__ import annotations +import gc import os import unittest from pathlib import Path @@ -474,6 +475,21 @@ class WSIReaderTests: class Tests(unittest.TestCase): backend = None + def tearDown(self): + """Force deterministic cleanup of any backend WSI handles. + + ``LoadImage`` calls ``reader.read`` and then discards the returned + object after ``get_data`` (see ``monai/transforms/io/array.py``); + for WSI readers that object is a ``TiffFile`` / ``OpenSlide`` / + ``CuImage`` instance that owns an open file descriptor.

The issue occurs in the segmentation code path (`_get_seg_data`, line 898) where `lastImagePositionPatient` is always set from the frame metadata regardless of the number of frames. For a single-frame segmentation, the first and last positions are identical, producing `0 / 0`. ## Solution Added an `n > 1` guard before computing the z-axis direction vector from `lastImagePositionPatient`. For single-slice volumes, the z-axis column of the affine remains as the identity `[0, 0, 1, 0]` from `np.eye(4)`, which is a correct default — there is no meaningful z-direction for a single slice. ## Verification ```python import numpy as np # Single-slice scenario (n=1) — previously caused ZeroDivisionError n = 1 sx, sy, sz = 0.0, 0.0, 0.0 t1n, t2n, t3n = 0.0, 0.0, 0.0 affine = np.eye(4) if n > 1: affine[0, 2] = (t1n - sx) / (n - 1) affine[1, 2] = (t2n - sy) / (n - 1) affine[2, 2] = (t3n - sz) / (n - 1) print(f'z-axis column: {affine[:, 2]}') # [0, 0, 1, 0] — identity ✓ # Normal multi-slice case (n=10) — still works correctly n = 10 t1n, t2n, t3n = 0.0, 0.0, 45.0 affine2 = np.eye(4) if n > 1: affine2[0, 2] = (t1n - sx) / (n - 1) affine2[1, 2] = (t2n - sy) / (n - 1) affine2[2, 2] = (t3n - sz) / (n - 1) print(f'z-axis column: {affine2[:, 2]}') # [0, 0, 5.0, 0] — correct direction ✓ ``` --- **About the Author:** Raphael Malikian — Clinical AI Solutions Architect.

An absent, out-of-range, or duplicated entry subtracts targets that were never counted, leaving `num_targets` too small. Since `compute_froc_curve_data` divides cumulative true positives by `num_targets`, this inflates the reported sensitivity. The count is now the labels in `[1, max_label]` that are not excluded, computed in the existing loop.

This `VAR=value command` syntax is not supported by Windows `cmd.exe` or PowerShell, so the documented commands fail out of the box on Windows. This adds short cmd.exe and PowerShell snippets to both install flows (Option 1 system-wide and Option 2 editable): set the environment variable first, then run the existing `pip install` command. The `set BUILD_MONAI=1` form is the one confirmed working on Windows 11 in the issue thread. ### Types of changes - [x] Non-breaking change (documentation only). - [x] Documentation updated. ### How tested - Verified the new `bat`/`powershell` fenced blocks use valid Pygments lexers and lex without error tokens, so the strict docs build (`build_docs.yml`) emits no new warnings. - pre-commit markdown hooks (end-of-file, trailing-whitespace, mixed-line-ending) pass on the changed file.

GPU implementations of KDTrees exist, but I did a little benchmarking and found that they are slower than the full EDT since the distance computations are embarrassingly parallel and well-suited to the hardware (gpu goes brrr), so I left that path unchanged. Measured speedups (on my M3 mac, and Intel Cascade Lake) range from 1.5x for small inputs to 16x for larger volumes and noisier data. I think existing test coverage is good enough that we don't need more here - all pass for me, and I've spot checked a few problems to ensure identical output metrics. Edit: have added some more tests per the coderabbit's suggestions. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [ ] New tests added to cover the changes. - [x] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [x] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [x] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder. --------- Signed-off-by: J Berg Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/metrics/utils.py | 25 ++++++++++++++- tests/metrics/test_surface_distance.py | 43 ++++++++++++++++++++++++++ 2 files changed, 67 insertions(+), 1 deletion(-) diff --git a/monai/metrics/utils.py b/monai/metrics/utils.py index bee0d7bf21..443be953b0 100644 --- a/monai/metrics/utils.py +++ b/monai/metrics/utils.py @@ -38,6 +38,7 @@ binary_erosion, _ = optional_import("scipy.ndimage", name="binary_erosion") distance_transform_edt, _ = optional_import("scipy.ndimage", name="distance_transform_edt") distance_transform_cdt, _ = optional_import("scipy.ndimage", name="distance_transform_cdt") +KDTree, has_scipy_kdtree = optional_import("scipy.spatial", name="KDTree") scipy_ndimage, has_scipy_ndimage = optional_import("scipy.ndimage") cupy, has_cupy = optional_import("cupy") @@ -269,7 +270,8 @@ def get_surface_distance( distance_metric: : [``"euclidean"``, ``"chessboard"``, ``"taxicab"``] the metric used to compute surface distance.

Passing `c=True` produced `--c True`, `val=True` produced `--val True`, and likewise for `use_compressed` and `disable_checkpointing`. `nnUNetv2_train` declares these as `store_true`, so the trailing `True` is parsed as a positional argument and the command fails. A falsy `pretrained_weights` was similarly emitted as `-pretrained_weights False` instead of being omitted. The builder now appends `store_true` flags only when their value is truthy and skips them otherwise, and includes `pretrained_weights`/`-p` only when given a real path. Regular value kwargs and the existing `--npz` handling are unchanged. Fixes #8941, originally flagged in a review thread on #8887. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. --------- Signed-off-by: Soumya Snigdha Kundu --- monai/apps/nnunet/nnunetv2_runner.py | 13 +++- tests/apps/nnunet/__init__.py | 10 +++ .../nnunet/test_nnunetv2_runner_command.py | 78 +++++++++++++++++++ 3 files changed, 98 insertions(+), 3 deletions(-) create mode 100644 tests/apps/nnunet/__init__.py create mode 100644 tests/apps/nnunet/test_nnunetv2_runner_command.py diff --git a/monai/apps/nnunet/nnunetv2_runner.py b/monai/apps/nnunet/nnunetv2_runner.py index 547e73332f..db00929e71 100644 --- a/monai/apps/nnunet/nnunetv2_runner.py +++ b/monai/apps/nnunet/nnunetv2_runner.py @@ -596,9 +596,16 @@ def train_single_model_command( if self.export_validation_probabilities: cmd.append("--npz") + store_true_flags = {"c", "val", "use_compressed", "disable_checkpointing"} for _key, _value in kwargs.items(): - prefix = "-" if _key in {"p", "pretrained_weights"} else "--" - cmd += [f"{prefix}{_key}", str(_value)] + if _key in store_true_flags: + if _value: + cmd.append(f"--{_key}") + elif _key in {"p", "pretrained_weights"}: + if _value: + cmd += [f"-{_key}", str(_value)] + else: + cmd += [f"--{_key}", str(_value)] cmd_str: list[str] = [str(c) for c in cmd] @@ -758,7 +765,7 @@ def validate_single_model(self, config: str, fold: int, **kwargs: Any) -> None: kwargs: this optional parameter allows you to specify additional arguments defined in the ``train_single_model`` method.

This adds a `rotate_order` parameter following the convention of `scipy.spatial.transform.Rotation.from_euler`: a string of up to three axes from `{x, y, z}`, where lower case selects extrinsic rotations (about the fixed world axes) and upper case selects intrinsic rotations (about the moving body axes). The default `"XYZ"` reproduces the previous behaviour exactly, so existing pipelines are unaffected. The name avoids collision with the spline interpolation order already selected via `mode`. The parameter is threaded through `functional.rotate`, `Rotate`, `RandRotate`, `AffineGrid`, `RandAffineGrid`, `Affine`, `RandAffine` and their dictionary variants. Invalid sequences raise `ValueError`, and 2D inputs ignore it. A new test module checks that the default matches the legacy matrix, that every supported axis sequence matches scipy for both the numpy and torch backends, that invalid sequences raise, that 2D inputs ignore the order, and that the `Rotate` transform honours it while remaining invertible. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. - [x] In-line docstrings updated. --------- Signed-off-by: Soumya Snigdha Kundu Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/transforms/spatial/array.py | 20 +++- monai/transforms/spatial/dictionary.py | 12 ++- monai/transforms/spatial/functional.py | 9 +- monai/transforms/utils.py | 90 +++++++++++++----- tests/transforms/test_create_rotate_order.py | 99 ++++++++++++++++++++ 5 files changed, 201 insertions(+), 29 deletions(-) create mode 100644 tests/transforms/test_create_rotate_order.py diff --git a/monai/transforms/spatial/array.py b/monai/transforms/spatial/array.py index 1fd6baf09a..2d3edaeed5 100644 --- a/monai/transforms/spatial/array.py +++ b/monai/transforms/spatial/array.py @@ -936,6 +936,9 @@ class Rotate(InvertibleTransform, LazyTransform): the output data type is always ``float32``. lazy: a flag to indicate whether this transform should execute lazily or not.

How to prepare a release

[!NOTE] Relevant for maintainers with write access only.

  1. Switch to a new branch from main.
  2. Run npm test to ensure all tests are passing.
  3. Update the version in https://github.com/actions/cache/blob/main/package.json.
  4. Run npm run build to update the compiled files.
  5. Update this https://github.com/actions/cache/blob/main/RELEASES.md with the new version and changes in the ## Changelog section.
  6. Run licensed cache to update the license report.
  7. Run licensed status and resolve any warnings by updating the https://github.com/actions/cache/blob/main/.licensed.yml file with the exceptions.
  8. Commit your changes and push your branch upstream.
  9. Open a pull request against main and get it reviewed and merged.
  10. Draft a new release https://github.com/actions/cache/releases use the same version number used in package.json
    1. Create a new tag with the version number.
    2. Auto generate release notes and update them to match the changes you made in RELEASES.md.
    3. Toggle the set as the latest release option.
    4. Publish the release.
  11. Navigate to https://github.com/actions/cache/actions/workflows/release-new-action-version.yml
    1. There should be a workflow run queued with the same version number.
    2. Approve the run to publish the new version and update the major tags for this action.

Per #7851, this breaks `DataLoader` collation when the weight map is a separate key and images differ in shape. This documents the behavior on both the array and dict transforms, and notes that `w_key` should be added to `keys` to get a cropped weight map. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] In-line docstrings updated. --------- Signed-off-by: Soumya Snigdha Kundu --- monai/transforms/croppad/array.py | 1 + monai/transforms/croppad/dictionary.py | 6 +++++- 2 files changed, 6 insertions(+), 1 deletion(-) diff --git a/monai/transforms/croppad/array.py b/monai/transforms/croppad/array.py index b23fbac7d9..4b18c74b2d 100644 --- a/monai/transforms/croppad/array.py +++ b/monai/transforms/croppad/array.py @@ -965,6 +965,7 @@ class RandWeightedCrop(Randomizable, TraceableTransform, LazyTransform, MultiSam weight_map: weight map used to generate patch samples.

Subsequent changes will look into re-enabling a subset of tests for macOS. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [ ] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder. --------- Signed-off-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- .github/workflows/cicd_tests.yml | 17 +++++++++++++---- 1 file changed, 13 insertions(+), 4 deletions(-) diff --git a/.github/workflows/cicd_tests.yml b/.github/workflows/cicd_tests.yml index 8510663cd8..e371dac76e 100644 --- a/.github/workflows/cicd_tests.yml +++ b/.github/workflows/cicd_tests.yml @@ -171,7 +171,7 @@ jobs: strategy: fail-fast: false matrix: - os: [windows-latest, ubuntu-latest] # macOS-latest omitted for now for being very slow, see #8864 + os: [windows-latest, ubuntu-latest, macOS-latest] # macOS-latest is very slow (#8864), testing install only timeout-minutes: 120 env: QUICKTEST: True @@ -223,19 +223,28 @@ jobs: cat "requirements-dev.txt" python -m pip install --no-build-isolation -r requirements-dev.txt python -m pip list - python -m pip install -e . # test no compile installation + python -m pip install --no-build-isolation -e . # test no compile installation shell: bash - name: Run compiled (${{ runner.os }}) run: | python -m pip uninstall -y monai - BUILD_MONAI=1 python -m pip install -e . # compile the cpp extensions + BUILD_MONAI=1 python -m pip install --no-build-isolation -e . # compile the cpp extensions shell: bash - - name: Run quick tests + - if: runner.os != 'macOS' + name: Run full tests run: | python -c 'import torch; print(torch.__version__); print(torch.rand(5,3))' python -c "import monai; monai.config.print_config()" python -m unittest -v shell: bash + - if: runner.os == 'macOS' + name: Run min tests + run: | + python -c 'import torch; print(torch.__version__); print(torch.rand(5,3))' + python -c "import monai; monai.config.print_config()" + # TODO: enable large range of macOS tests which don't take a very long time + ./runtests.sh --min + shell: bash packaging: # Test package generation runs-on: ubuntu-latest From eb74488c5be06e97d8ee5d6bdec2488ac3903a1c Mon Sep 17 00:00:00 2001 From: Md Salman Shams <68110323+MDSALMANSHAMS@users.noreply.github.com> Date: Sat, 4 Jul 2026 01:44:19 +0530 Subject: [PATCH 33/72] Add AbsoluteVolumeDifferenceMetric to monai.metrics (#8945) ## Summary Closes #4009. Adds AbsoluteVolumeDifferenceMetric and a standalone compute_absolute_volume_difference() function to monai.metrics. **Why AVD?** Dice score is known to be overly sensitive for small-object segmentation (e.g. retinal fluid sub-types in OCT volumes - SRF, IRF, PED), because small volume differences produce large Dice swings. AVD directly reflects volume size discrepancy, making it the standard evaluation metric in the RETOUCH retinal OCT fluid benchmark (Bogunovic et al., IEEE TMI 2019). ## Changes - **monai/metrics/absolute_volume_difference.py** - new file: - AbsoluteVolumeDifferenceMetric(CumulativeIterationMetric) - cumulative class matching the DiceMetric / MeanIoU interface. Supports include_background, eduction, get_not_nans, ignore_empty. - compute_absolute_volume_difference() - standalone function returning shape [B, C]. - **monai/metrics/__init__.py** - exports both new symbols. - ** ests/metrics/test_absolute_volume_difference.py** - 14 unit tests. ## Test plan - [x] Perfect prediction returns zero - [x] Known volume difference (hand-verified) - [x] ignore_empty=True sets NaN for empty ground-truth channels - [x] ignore_empty=False returns raw absolute difference - [x] include_background=False strips channel 0 - [x] 3D spatial volumes (BCDHW) - [x] Multi-class output shape - [x] Cumulative accumulation across batches - [x] Buffer reset - [x] Shape mismatch raises ValueError - [x] Fewer than 3 dimensions raises ValueError - [x] Top-level import from monai.metrics All 14 tests pass (python -m unittest tests.metrics.test_absolute_volume_difference -v). > This PR was authored with the assistance of an AI coding assistant. --------- Signed-off-by: MDSALMANSHAMS Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- docs/source/metrics.rst | 7 + monai/metrics/__init__.py | 1 + monai/metrics/absolute_volume_difference.py | 180 ++++++++++++++++++ .../test_absolute_volume_difference.py | 161 ++++++++++++++++ 4 files changed, 349 insertions(+) create mode 100644 monai/metrics/absolute_volume_difference.py create mode 100644 tests/metrics/test_absolute_volume_difference.py diff --git a/docs/source/metrics.rst b/docs/source/metrics.rst index 654958bbbf..ebd745e795 100644 --- a/docs/source/metrics.rst +++ b/docs/source/metrics.rst @@ -116,6 +116,13 @@ Metrics .. autoclass:: SurfaceDiceMetric :members: +`Absolute volume difference` +---------------------------- +.. autofunction:: compute_absolute_volume_difference + +.. autoclass:: AbsoluteVolumeDifferenceMetric + :members: + `PanopticQualityMetric` ----------------------- .. autofunction:: compute_panoptic_quality diff --git a/monai/metrics/__init__.py b/monai/metrics/__init__.py index 2265dd3a3f..f55f92db1b 100644 --- a/monai/metrics/__init__.py +++ b/monai/metrics/__init__.py @@ -11,6 +11,7 @@ from __future__ import annotations +from .absolute_volume_difference import AbsoluteVolumeDifferenceMetric, compute_absolute_volume_difference from .active_learning_metrics import LabelQualityScore, VarianceMetric, compute_variance, label_quality_score from .average_precision import AveragePrecisionMetric, compute_average_precision from .calibration import CalibrationErrorMetric, CalibrationReduction, calibration_binning diff --git a/monai/metrics/absolute_volume_difference.py b/monai/metrics/absolute_volume_difference.py new file mode 100644 index 0000000000..92e18acea2 --- /dev/null +++ b/monai/metrics/absolute_volume_difference.py @@ -0,0 +1,180 @@ +# Copyright (c) MONAI Consortium +# Licensed under the Apache License, Version 2.0 (the "License"); +# you may not use this file except in compliance with the License. +# You may obtain a copy of the License at +# http://www.apache.org/licenses/LICENSE-2.0 +# Unless required by applicable law or agreed to in writing, software +# distributed under the License is distributed on an "AS IS" BASIS, +# WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. +# See the License for the specific language governing permissions and +# limitations under the License. + +from __future__ import annotations + +import torch + +from monai.metrics.utils import do_metric_reduction, ignore_background +from monai.utils import MetricReduction + +from .metric import CumulativeIterationMetric + +__all__ = ["AbsoluteVolumeDifferenceMetric", "compute_absolute_volume_difference"] + + +class AbsoluteVolumeDifferenceMetric(CumulativeIterationMetric): + """ + Compute the Absolute Volume Difference (AVD) between predicted and ground-truth + segmentation masks. + + AVD measures the absolute difference in the number of foreground voxels between + prediction and ground truth, per class.

That is equivalent to shifting the image directly, so the `nonzero=False` branch now does `img + factor * std(img)`. Output is bit-for-bit identical and the `nonzero=True` path is untouched. `RandStdShiftIntensity` benefits too, since it also defaults to `nonzero=False`. Measured across 2D/3D, single and multi channel, float32 and float64 on both backends (best-of-3, CPU); output verified equal in every configuration: | shape | dtype | backend | current (ms) | proposed (ms) | speedup | |---|---|---|---|---|---| | 1x256x256 | f32 | numpy | 0.123 | 0.048 | 2.58x | | 1x256x256 | f32 | torch | 0.563 | 0.039 | 14.47x | | 1x1024x1024 | f32 | numpy | 3.016 | 1.294 | 2.33x | | 1x1024x1024 | f32 | torch | 7.040 | 0.274 | 25.66x | | 1x1024x1024 | f64 | torch | 9.644 | 0.601 | 16.04x | | 1x64x64x64 | f32 | numpy | 0.637 | 0.251 | 2.54x | | 1x64x64x64 | f64 | torch | 2.646 | 0.095 | 27.84x | | 1x128x128x128 | f32 | numpy | 7.019 | 2.914 | 2.41x | | 1x128x128x128 | f32 | torch | 41.618 | 0.630 | 66.09x | | 1x128x128x128 | f64 | torch | 44.534 | 1.825 | 24.40x | | 4x96x96x96 | f32 | torch | 68.152 | 1.357 | 50.23x | | 4x160x160x160 | f32 | numpy | 128.429 | 82.662 | 1.55x | | 4x160x160x160 | f32 | torch | 342.641 | 16.727 | 20.48x | | 4x160x160x160 | f64 | torch | 354.009 | 41.652 | 8.50x | numpy ranges 1.55x to 2.65x and torch 8.5x to 66x across the full sweep; the largest gains are on torch, where all-True boolean-mask indexing is especially costly. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). --------- Signed-off-by: Soumya Snigdha Kundu Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/transforms/intensity/array.py | 7 ++----- 1 file changed, 2 insertions(+), 5 deletions(-) diff --git a/monai/transforms/intensity/array.py b/monai/transforms/intensity/array.py index 243355b5e3..d941f43ad7 100644 --- a/monai/transforms/intensity/array.py +++ b/monai/transforms/intensity/array.py @@ -354,17 +354,14 @@ def __init__( self.dtype = dtype def _stdshift(self, img: NdarrayOrTensor) -> NdarrayOrTensor: - ones: Callable std: Callable if isinstance(img, torch.Tensor): - ones = torch.ones std = partial(torch.std, unbiased=False) else: - ones = np.ones std = np.std - slices = (img != 0) if self.nonzero else ones(img.shape, dtype=bool) - if slices.any(): + slices = (img != 0) if self.nonzero else () + if not self.nonzero or (isinstance(slices, (np.ndarray, torch.Tensor)) and slices.any()): offset = self.factor * std(img[slices]) img[slices] = img[slices] + offset return img From 36a6f0b6395377a61dd750dd2241b33ed263710f Mon Sep 17 00:00:00 2001 From: Farhad Ramezanghorbani Date: Fri, 10 Jul 2026 14:00:56 -0600 Subject: [PATCH 36/72] HyenaUnetR (SwinUnetR + HyenaND): subquadratic alternative to windowed self-attention (#8958) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit # HyenaUnetR (SwinUnetR + HyenaND): subquadratic alternative to windowed self-attention Upstreams the four-variant PanTS matrix from NeurIPS 2026 paper id 26539 (*Native Multi-Dimensional Subquadratic Operators via Input Dependent Long Convolutions*). HyenaND replaces windowed self-attention with a gated long convolution backed by FFT global receptive field at O(N log N) cost instead of attention's O(N²)-within-a-window. ## Optional dependency: nvsubquadratic The Hyena operators are backed by [`nvsubquadratic`](https://github.com/NVIDIA-BioNeMo/nvSubquadratic) ([PyPI](https://pypi.org/project/nvsubquadratic/)), NVIDIA's PyTorch-native library of subquadratic attention alternatives. It is **optional** — gated via `optional_import`, installed through the new `hyena` extra: ​```bash pip install 'monai[hyena]' ​``` `monai` core, `requirements-dev.txt`, and `pip install monai[all]` are unaffected. Without the package, `import monai` and `SwinUNETR(use_hyena=False)` behave exactly as before; the Hyena classes raise a clear `ImportError` only when constructed, and the Hyena tests skip via `@skipUnless(is_nvsubquadratic_available(), ...)`. ### Public surface * `monai.networks.blocks`: `HyenaMixer`, `HyenaTransformerBlock`, `DepthwiseFFTConv{2,3}d`. * `monai.networks.nets.SwinUNETR`: new `use_hyena` / `hyena_stages` / `hyena_*` kwargs threaded through `SwinTransformer` → `BasicLayer`. * `monai.networks.nets.HyenaNDUNETR`: thin `SwinUNETR` subclass with `from_paper_variant("HHHH" | "HAHA" | "HHAA")`. * New `[hyena]` extras_require → `pip install 'monai[hyena]'` (`nvsubquadratic` 0.1.0 on PyPI). nvsubquadratic is gated through optional_import; SwinUNETR(use_hyena=False) never imports it. ```python from monai.networks.nets import HyenaNDUNETR net = HyenaNDUNETR.get_variant("HHAA", in_channels=1, out_channels=29, feature_size=48) ``` ## Tests 72 new tests across test_hyena_block.py (40), test_swin_unetr.py (15 Hyena classes), test_hyena_nd_unetr.py (17). ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder. --------- Signed-off-by: Farhad Ramezanghorbani Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Claude Opus 4.7 (1M context) --- .github/workflows/cicd_tests.yml | 49 ++ .github/workflows/pythonapp-hyena-gpu.yml | 74 +++ CHANGELOG.md | 5 + docs/source/installation.md | 9 +- docs/source/networks.rst | 22 + monai/networks/blocks/__init__.py | 7 + monai/networks/blocks/hyena.py | 555 +++++++++++++++++++++ monai/networks/nets/__init__.py | 1 + monai/networks/nets/hyena_nd_unetr.py | 151 ++++++ monai/networks/nets/swin_unetr.py | 278 +++++++++-- setup.cfg | 2 + tests/min_tests.py | 2 + tests/networks/blocks/test_hyena_block.py | 336 +++++++++++++ tests/networks/nets/test_hyena_nd_unetr.py | 137 +++++ tests/networks/nets/test_swin_unetr.py | 209 +++++++- 15 files changed, 1779 insertions(+), 58 deletions(-) create mode 100644 .github/workflows/pythonapp-hyena-gpu.yml create mode 100644 monai/networks/blocks/hyena.py create mode 100644 monai/networks/nets/hyena_nd_unetr.py create mode 100644 tests/networks/blocks/test_hyena_block.py create mode 100644 tests/networks/nets/test_hyena_nd_unetr.py diff --git a/.github/workflows/cicd_tests.yml b/.github/workflows/cicd_tests.yml index e371dac76e..d48e3a02f2 100644 --- a/.github/workflows/cicd_tests.yml +++ b/.github/workflows/cicd_tests.yml @@ -246,6 +246,55 @@ jobs: ./runtests.sh --min shell: bash + hyena-dep: # Optional HyenaND dependency + the no-CUDA Hyena tests. + # nvsubquadratic >= 0.1.1 supports Python >= 3.10 and keeps its CUDA-kernel sdist + # (subquadratic-ops-torch-cu12) plus the megatron / dali / timm packages in opt-in + # extras, so it installs on a CPU runner.

With `padding_mode="zeros"`, even a **zero displacement field** then yields: - `nan` output for 2D single-row/column inputs, and - all-zeros output for 3D single-slice inputs, instead of returning the input image unchanged. #### Fix Clamp the denominator to 1 so the lone voxel maps to `-1`. This mirrors the guard MONAI already applies in `monai.networks.utils.normalize_transform`, which performs the identical `align_corners=True` normalization and clamps the size with `norm[norm <= 1.0] = 2.0` to avoid exactly this division by zero. Non-singleton dimensions are numerically unchanged. ```python grid[..., i] = grid[..., i] * 2 / max(dim - 1, 1) - 1 ``` #### Verification Added `test_singleton_spatial_dim` (2D single-row, 2D single-column, 3D single-slice). With a zero displacement field the warped output now equals the input and contains no `nan`. The test fails on the current code and passes with the fix; the existing `Warp` tests are unaffected. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. - [x] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [x] In-line docstrings updated. --------- Signed-off-by: VenkateswarluNagineni --- monai/networks/blocks/warp.py | 5 ++++- tests/networks/blocks/warp/test_warp.py | 23 +++++++++++++++++++++++ 2 files changed, 27 insertions(+), 1 deletion(-) diff --git a/monai/networks/blocks/warp.py b/monai/networks/blocks/warp.py index ddd3a350d5..a2bfe21c93 100644 --- a/monai/networks/blocks/warp.py +++ b/monai/networks/blocks/warp.py @@ -155,7 +155,10 @@ def forward(self, image: torch.Tensor, ddf: torch.Tensor): if not _use_compiled: # pytorch native grid_sample for i, dim in enumerate(grid.shape[1:-1]): - grid[..., i] = grid[..., i] * 2 / (dim - 1) - 1 + # guard against a singleton spatial dim (e.g. a single-slice volume), where + # ``dim - 1 == 0`` would divide by zero; clamp the denominator to 1 so the lone + # voxel maps to -1, matching ``monai.networks.utils.normalize_transform``. + grid[..., i] = grid[..., i] * 2 / max(dim - 1, 1) - 1 index_ordering: list[int] = list(range(spatial_dims - 1, -1, -1)) grid = grid[..., index_ordering] # z, y, x -> x, y, z return F.grid_sample( diff --git a/tests/networks/blocks/warp/test_warp.py b/tests/networks/blocks/warp/test_warp.py index 93af559790..6ee4230783 100644 --- a/tests/networks/blocks/warp/test_warp.py +++ b/tests/networks/blocks/warp/test_warp.py @@ -12,6 +12,7 @@ import unittest from pathlib import Path +from unittest import mock import numpy as np import torch @@ -138,6 +139,28 @@ def test_ill_shape(self): with self.assertRaisesRegex(ValueError, ""): warp_layer(image=torch.arange(4).reshape((1, 1, 2, 2)).to(dtype=torch.float), ddf=torch.zeros(1, 2, 3, 3)) + @mock.patch("monai.networks.blocks.warp.USE_COMPILED", False) + def test_singleton_spatial_dim(self): + """ + Regression test for a singleton spatial dimension (a single-slice volume or a + single-row/column image), where the grid normalization ``* 2 / (dim - 1)`` previously + divided by zero. + + The native ``grid_sample`` path is forced via ``USE_COMPILED=False`` because only that + branch normalizes the grid; the csrc ``grid_pull`` path is unaffected. ``padding_mode`` + is ``"zeros"`` so an out-of-range (pre-fix ``nan``) coordinate maps to 0 and exposes the + bug, whereas ``"border"``/``"reflection"`` would clamp onto the lone voxel and mask it. + For a zero displacement field the warped output must contain no ``nan`` and must equal + the input image. + """ + for shape, ndim in [((1, 1, 1, 4, 4), 3), ((1, 1, 1, 5), 2), ((1, 1, 5, 1), 2)]: + image = torch.rand(*shape) + ddf = torch.zeros(shape[0], ndim, *shape[2:]) + warp_layer = Warp(mode="bilinear", padding_mode="zeros") + result = warp_layer(image, ddf) + self.assertFalse(torch.isnan(result).any(), f"NaN in warp output for shape {shape}") + np.testing.assert_allclose(result.cpu().numpy(), image.cpu().numpy(), rtol=1e-4, atol=1e-4) + def test_grad(self): for b in GridSampleMode: for p in GridSamplePadMode: From 1a26bc9e282c8817c2e9d5ed6f5cec5c405e83db Mon Sep 17 00:00:00 2001 From: Raphael Malikian Date: Sat, 11 Jul 2026 12:03:01 -0700 Subject: [PATCH 38/72] fix: warn when PydicomReader cannot determine affine from DICOM metadata (Fixes #8468) (#8922) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Fixes #8468 ## Problem `PydicomReader._get_affine()` silently returns an identity matrix when `ImageOrientationPatient` (00200037) or `ImagePositionPatient` (00200032) tags are missing from DICOM metadata. This commonly occurs with multiframe DICOM files (e.g., Enhanced CT) where spatial metadata is stored in `SharedFunctionalGroupsSequence` or `PerFrameFunctionalGroupsSequence` rather than at the top level. The silent fallback to an identity matrix leads to incorrect spatial metadata downstream, causing confusion in downstream processing pipelines. ## Solution Added a `warnings.warn()` call in `PydicomReader._get_affine()` to inform users when the affine matrix cannot be determined from the available metadata. The warning: - Explains which DICOM tags are missing - Notes that the identity matrix may be incorrect - Identifies multiframe DICOM files as a common cause - Suggests using `ITKReader` as an alternative that handles these cases correctly ## Verification ```python import warnings import numpy as np metadata = {} with warnings.catch_warnings(record=True) as w: warnings.simplefilter('always') affine = np.eye(4) if not ('00200037' in metadata and '00200032' in metadata): warnings.warn( "PydicomReader: ImageOrientationPatient (00200037) or " "ImagePositionPatient (00200032) not found in DICOM metadata.

When `ImageOrientationPatient` (0020,0037) and `ImagePositionPatient` (0020,0032) are missing from the metadata (e.g. some multi-frame Enhanced DICOM), `PydicomReader._get_affine` returned `np.eye(4)` with no indication, so downstream orientation and spacing were silently wrong. This adds a `UserWarning` that names the missing tags, states the affine defaults to identity, and suggests `ITKReader` for such files. The fallback behaviour itself is unchanged — this only surfaces it. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. ### Testing Added `tests/data/test_pydicom_reader.py` asserting that `_get_affine` warns (`UserWarning`) and returns identity when the orientation/position tags are absent or only partially present. ``` python -m unittest tests.data.test_pydicom_reader # Ran 2 tests ...

The grid is built from `torch.arange` (integer dtype) and `self.ref_grid` was assigned `grid.to(ddf)` before the jitter block, so `grid += torch.rand_like(grid)` mutated a local that was never returned, and `torch.rand_like` raises `NotImplementedError` on an integer tensor anyway. Separately, `fork_rng(enabled=seed)` disabled RNG forking when `seed` took its default of `0`, leaking the seeded state into the global RNG. The grid is now cast to `ddf` before jittering, the jittered tensor is assigned to `self.ref_grid`, and `fork_rng()` isolates the seeded draw. The non-jitter path is unchanged. A regression test covers the float/non-integer jittered grid, the integer un-jittered grid, and per-seed reproducibility; it fails before this change with `NotImplementedError`. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. --------- Signed-off-by: Soumya Snigdha Kundu Signed-off-by: Soumya Snigdha Kundu Signed-off-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/networks/blocks/warp.py | 5 +++-- tests/networks/blocks/warp/test_warp.py | 15 +++++++++++++++ 2 files changed, 18 insertions(+), 2 deletions(-) diff --git a/monai/networks/blocks/warp.py b/monai/networks/blocks/warp.py index a2bfe21c93..1878662916 100644 --- a/monai/networks/blocks/warp.py +++ b/monai/networks/blocks/warp.py @@ -121,12 +121,13 @@ def get_reference_grid(self, ddf: torch.Tensor, jitter: bool = False, seed: int mesh_points = [torch.arange(0, dim) for dim in ddf.shape[2:]] grid = torch.stack(meshgrid_ij(*mesh_points), dim=0) # (spatial_dims, ...) grid = torch.stack([grid] * ddf.shape[0], dim=0) # (batch, spatial_dims, ...) - self.ref_grid = grid.to(ddf) + grid = grid.to(ddf) if jitter: # Define reference grid on non-integer values - with torch.random.fork_rng(enabled=seed): + with torch.random.fork_rng(): torch.random.manual_seed(seed) grid += torch.rand_like(grid) + self.ref_grid = grid self.ref_grid.requires_grad = False return self.ref_grid diff --git a/tests/networks/blocks/warp/test_warp.py b/tests/networks/blocks/warp/test_warp.py index 6ee4230783..1f23664234 100644 --- a/tests/networks/blocks/warp/test_warp.py +++ b/tests/networks/blocks/warp/test_warp.py @@ -139,6 +139,21 @@ def test_ill_shape(self): with self.assertRaisesRegex(ValueError, ""): warp_layer(image=torch.arange(4).reshape((1, 1, 2, 2)).to(dtype=torch.float), ddf=torch.zeros(1, 2, 3, 3)) + def test_jitter(self): + ddf = torch.zeros(1, 2, 4, 5) + grid = Warp(jitter=True).get_reference_grid(ddf, jitter=True, seed=0) + self.assertTrue(grid.is_floating_point()) + self.assertFalse(torch.equal(grid, grid.round())) + + grid = Warp().get_reference_grid(ddf, jitter=False) + self.assertTrue(torch.equal(grid, grid.round())) + + same = Warp().get_reference_grid(ddf, jitter=True, seed=7) + repeat = Warp().get_reference_grid(ddf, jitter=True, seed=7) + other = Warp().get_reference_grid(ddf, jitter=True, seed=8) + self.assertTrue(torch.equal(same, repeat)) + self.assertFalse(torch.equal(same, other)) + @mock.patch("monai.networks.blocks.warp.USE_COMPILED", False) def test_singleton_spatial_dim(self): """ From 3a458fe790fa41ed30f88f396c39dc2163fa7a25 Mon Sep 17 00:00:00 2001 From: "pre-commit-ci[bot]" <66853113+pre-commit-ci[bot]@users.noreply.github.com> Date: Wed, 15 Jul 2026 17:07:45 +0100 Subject: [PATCH 41/72] [pre-commit.ci] pre-commit suggestions (#8984) MIME-Version: 1.0 Content-Type: text/plain;

Both allocate large transient arrays. This counts labels with a single full-field `lib.bincount` (zeroing index 0 to drop background), and builds the mask with a boolean lookup-table gather (`keep[features]`) instead of `isin`. Output is bit-identical, verified across 2D and 3D at several foreground fractions and component counts, and the numpy and cupy/cucim paths are covered unchanged. The `isin` replacement is the dominant win on both time and peak memory; the `bincount` change removes the redundant `nonzero` index arrays and gathered copy on top. | case | metric | before | after | improvement | |---|---|---|---|---| | 3D 192^3, fg 50% | time | 82.0 ms | 8.6 ms | 9.5x | | 3D 192^3, fg 50% | peak transient mem | 108.0 MB | 7.2 MB | 15x | | 2D 1024^2, fg 60% | time | 21.5 ms | 1.8 ms | 11.7x | | 2D 1024^2, fg 60% | peak transient mem | 18.0 MB | 1.4 MB | 12.9x | | 3D 128^3, fg 5% (48k comps) | time | 10.7 ms | 6.2 ms | 1.7x | ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality).

After the first metric's CSV is written, `class_labels` is no longer `None`. It holds `["class0", ..., "classN", "mean"]`. On every subsequent metric the `else` branch runs and appends another `"mean"`, producing headers like `class0,class1,mean,mean,mean`. This hits any evaluation with two or more metrics in `metric_details`, for example Dice + IoU + Hausdorff. The only real caller `MetricsSaver` always passes `class_labels=None`. The first metric's CSV is correct, but every one after is structurally corrupt with mismatched header and data columns. The fix uses a local `labels` variable per iteration so the original `class_labels` parameter is never modified. The existing test only verified existence of subsequent metric files, not their headers. A regression test is included. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. --------- Signed-off-by: Soumya Snigdha Kundu Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/handlers/utils.py | 10 ++++----- tests/handlers/test_write_metrics_reports.py | 22 ++++++++++++++++++++ 2 files changed, 27 insertions(+), 5 deletions(-) diff --git a/monai/handlers/utils.py b/monai/handlers/utils.py index 02975039b3..47cc94838a 100644 --- a/monai/handlers/utils.py +++ b/monai/handlers/utils.py @@ -122,15 +122,15 @@ class mean median max 5percentile 95percentile notnans # add the average value of all classes to v if class_labels is None: - class_labels = ["class" + str(i) for i in range(v.shape[1])] + labels = ["class" + str(i) for i in range(v.shape[1])] else: - class_labels = [str(i) for i in class_labels] # ensure to have a list of str + labels = [str(i) for i in class_labels] # ensure to have a list of str - class_labels += ["mean"] + labels += ["mean"] v = np.concatenate([v, np.nanmean(v, axis=1, keepdims=True)], axis=1) with open(os.path.join(save_dir, f"{k}_raw.csv"), "w") as f: - f.write(f"filename{deli}{deli.join(class_labels)}\n") + f.write(f"filename{deli}{deli.join(labels)}\n") for i, b in enumerate(v): f.write( f"{images[i] if images is not None else str(i)}{deli}" @@ -164,7 +164,7 @@ def _compute_op(op: str, d: np.ndarray) -> Any: with open(os.path.join(save_dir, f"{k}_summary.csv"), "w") as f: f.write(f"class{deli}{deli.join(ops)}\n") for i, c in enumerate(np.transpose(v)): - f.write(f"{class_labels[i]}{deli}{deli.join([f'{_compute_op(k, c):.4f}' for k in ops])}\n") + f.write(f"{labels[i]}{deli}{deli.join([f'{_compute_op(k, c):.4f}' for k in ops])}\n") def from_engine(keys: KeysCollection, first: bool = False) -> Callable: diff --git a/tests/handlers/test_write_metrics_reports.py b/tests/handlers/test_write_metrics_reports.py index 1013f15d85..07cf46c122 100644 --- a/tests/handlers/test_write_metrics_reports.py +++ b/tests/handlers/test_write_metrics_reports.py @@ -63,6 +63,28 @@ def test_content(self): self.assertTrue(os.path.exists(os.path.join(tempdir, "metric4_raw.csv"))) self.assertTrue(os.path.exists(os.path.join(tempdir, "metric4_summary.csv"))) + def test_multi_metric_details_headers(self): + with tempfile.TemporaryDirectory() as tempdir: + write_metrics_reports( + save_dir=Path(tempdir), + images=["img1", "img2"], + metrics=None, + metric_details={ + "m1": torch.tensor([[1, 2, 3], [4, 5, 6]]), + "m2": torch.tensor([[7, 8], [9, 10]]), + "m3": torch.tensor([[11, 12, 13, 14], [15, 16, 17, 18]]), + }, + summary_ops=None, + deli=",", + output_type="csv", + ) + for name, nclass in [("m1", 3), ("m2", 2), ("m3", 4)]: + path = os.path.join(tempdir, f"{name}_raw.csv") + self.assertTrue(os.path.exists(path)) + with open(path) as f: + header = f.readline().strip().split(",") + self.assertEqual(header, ["filename"] + [f"class{i}" for i in range(nclass)] + ["mean"]) + if __name__ == "__main__": unittest.main() From 8690ae74a8a489d31fe1f9ac8ef0bff63165383e Mon Sep 17 00:00:00 2001 From: Oleksandr_Sanin Date: Thu, 30 Jul 2026 17:57:07 +0200 Subject: [PATCH 48/72] fix(MetaTensor): astype with torch dtype now returns MetaTensor preserving metadata (#8911) ## Summary - `MetaTensor.astype()` called with a torch dtype (e.g. `torch.int32`, `torch.float16`) was silently returning a plain `torch.Tensor`, discarding all metadata (affine matrix, spacing, applied_operations, and any custom keys). - Root cause: `out_type` was hardcoded to `torch.Tensor` instead of `type(self)` (`MetaTensor`), so `convert_data_type` set `track_meta=False` and stripped the metadata. - Fix: use `out_type = type(self)` when `mod_str == "torch"`, so `convert_data_type` receives `output_type=MetaTensor`, sets `track_meta=True`, and the dtype cast is performed while preserving all metadata. - The `auto3dseg/analyzer.py` module already annotated `label_tensor.astype(torch.int16)` as returning a `MetaTensor` (line 493), relying on this contract. Closes #8202 ## Test plan - [ ] Existing `test_astype` test updated to assert `isinstance(result, MetaTensor)` and that metadata keys survive the cast. - [ ] All 96 `tests/data/meta_tensor/` tests pass locally (0 failures). - [ ] Manual verification: ```python import torch from monai.data import MetaTensor t = MetaTensor(torch.tensor([1., 2., 3.]), meta={"fname": "scan.nii"}) result = t.astype(torch.int32) assert isinstance(result, MetaTensor) # was torch.Tensor before assert result.meta["fname"] == "scan.nii" # metadata preserved assert result.dtype == torch.int32 # dtype correctly cast ``` Signed-off-by: Oleksandr Sanin Co-authored-by: Claude Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/data/meta_tensor.py | 5 +++-- tests/data/meta_tensor/test_meta_tensor.py | 8 ++++++-- 2 files changed, 9 insertions(+), 4 deletions(-) diff --git a/monai/data/meta_tensor.py b/monai/data/meta_tensor.py index 965e76cf97..0dc5abb1b2 100644 --- a/monai/data/meta_tensor.py +++ b/monai/data/meta_tensor.py @@ -495,7 +495,8 @@ def astype(self, dtype, device=None, *_args, **_kwargs): _kwargs: additional kwargs (currently unused).

When `LoadImage` is given an explicit reader string whose optional dependency is unavailable, the original `OptionalImportError` is now propagated instead of being converted into a warning and silently falling back to another registered reader. Automatic reader selection with `reader=None` remains unchanged. ### Implementation - Propagate `OptionalImportError` for explicitly requested unavailable string readers. - Add an environment-independent regression test using mock readers. - Update reader initialization tests to reflect the new explicit-reader behavior when optional dependencies are unavailable. ### Compatibility This is an intentional behavior change for explicitly requested unavailable readers. The following behavior remains unchanged: - automatic reader selection with `reader=None` - default registration skipping unavailable optional readers - runtime fallback when an installed reader cannot read a file - public APIs and signatures This PR does not redesign explicit tuple/list reader semantics. ### Validation Executed locally: - `python -m tests.transforms.test_load_image` - `python -m tests.transforms.test_load_imaged` - `python -m tests.data.test_init_reader` - Ruff All executed tests passed. Some optional-backend tests were skipped as expected in the current environment. --------- Signed-off-by: Minsu Kim --- monai/transforms/io/array.py | 4 +- tests/data/test_init_reader.py | 26 +++++++++++-- tests/transforms/test_load_image.py | 57 ++++++++++++++++++++++++++++- 3 files changed, 78 insertions(+), 9 deletions(-) diff --git a/monai/transforms/io/array.py b/monai/transforms/io/array.py index aadd96763d..e5d127c4b9 100644 --- a/monai/transforms/io/array.py +++ b/monai/transforms/io/array.py @@ -210,9 +210,7 @@ def __init__( try: self.register(the_reader(*args, **kwargs)) except OptionalImportError: -

15x faster than mypy, adopted by PyTorch and JAX - Production-proven at Meta on 20M-line codebase - `preset="legacy"` matches mypy laxness for smooth migration - `# type: ignore` comments still respected - `pyrefly init` auto-migrates existing mypy configuration - `pyrefly suppress` establishes zero-error baseline instantly **Changes:** - Remove `[mypy]` config from setup.cfg (migrated to `[tool.pyrefly]`) - Remove `[tool.pytype]` from pyproject.toml (deprecated, no Python >3.12) - Add `[tool.pyrefly]` with `preset="legacy"` matching mypy laxness - Run `pyrefly suppress` to establish zero-error baseline - Update CI matrix: pytype + mypy → pyrefly - Update runtests.sh: --pytype + --mypy → --pyrefly - Update requirements-dev.txt, .gitignore, CONTRIBUTING.md - Update .github/workflows/cron.yml Fixes #8865 (pytype deprecation) --- Open with GitKraken --------- Signed-off-by: R.

Key features: - Patch n' Pack: multiple images concatenated into one sequence per group, with a per-image attention mask preventing cross-image attention - Factorised positional embeddings: separate learnable tables per spatial axis, allowing generalisation to unseen resolutions - Token dropout: configurable fraction of patch tokens dropped during training (float or callable) - Attention pooling: learned query attends over each image's tokens to produce a fixed-size per-image representation - QK normalisation: RMS normalisation on queries and keys (ViT-22B style) - 2D and 3D support: works for (C, H, W) and (C, H, W, D) inputs Changes: - monai/networks/nets/navit.py: new NaViT implementation - monai/networks/nets/__init__.py: export NaViT - tests/networks/nets/test_navit.py: 24 unit tests covering shape, variable resolutions, token dropout, auto-grouping, gradient flow, ill arguments, and forward validation - docs/source/networks.rst: autoclass entry - docs/source/whatsnew_1_5_2.md: feature description - CHANGELOG.md: entry under Unreleased Fixes # . ### Description A few sentences describing the changes proposed in this pull request. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [x] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [x] In-line docstrings updated. - [x] Documentation updated, tested `make html` command in the `docs/` folder. --------- Signed-off-by: Vikash Gupta Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- CHANGELOG.md | 1 + docs/source/networks.rst | 5 + monai/networks/nets/__init__.py | 1 + monai/networks/nets/navit.py | 585 ++++++++++++++++++++++++++++++ tests/min_tests.py | 1 + tests/networks/nets/test_navit.py | 233 ++++++++++++ 6 files changed, 826 insertions(+) create mode 100644 monai/networks/nets/navit.py create mode 100644 tests/networks/nets/test_navit.py diff --git a/CHANGELOG.md b/CHANGELOG.md index c8731ddb42..987a1d3a2e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -5,6 +5,7 @@ The format is based on [Keep a Changelog](http://keepachangelog.com/en/1.0.0/). ## [Unreleased] ### Added +* `NaViT` (`monai.networks.nets.NaViT`): Native Resolution Vision Transformer with Patch n' Pack, supporting variable-resolution 2D and 3D inputs.

3e2ff2b1f98eed7121e6c5860b761275fc63f2a3 Mon Sep 17 00:00:00 2001 From: Rafael Garcia-Dias Date: Mon, 17 Aug 2026 14:30:02 +0100 Subject: [PATCH 54/72] Fix GHSA-873f-pvrv-4x83: warn before executing a bundle's config in load()/run() (#9057) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary Fixes GHSA-873f-pvrv-4x83: https://github.com/Project-MONAI/MONAI/security/advisories/GHSA-873f-pvrv-4x83 `monai.bundle.load()`, with its default `model=None`, builds a bundle's network by parsing the bundle's own config through `create_workflow()`. That parsing resolves any `"_target_"` value to an importable callable with no allow list, and passes any `"$"`-prefixed value to Python `eval()`. `monai.bundle.run()` reaches the same code path via a caller-supplied `config_file`. Either way, this means loading or running a bundle whose config you haven't reviewed can execute arbitrary code. ### Design An earlier version of this fix added an opt-in `trust_remote_code` flag to `load()`. Per review discussion, that was dropped: MONAI has no mechanism to actually establish whether a bundle is trustworthy (unlike, say, a per-repo "has custom code" check), so a flag like that mostly teaches people to set it once and forget about it, without giving them a real basis to decide. Instead: - `create_workflow()` — the shared path both `load()` and `run()` use to parse a config file — now raises a `UserWarning` immediately before doing so, spelling out exactly what `"_target_"`/`"$"`-expression content can do and linking this advisory. - No behavior is blocked. Default behavior is unchanged other than the added warning: `load()`/`run()` still parse and execute the config exactly as before. - The warning applies uniformly to every caller of `create_workflow()`, not just `load()`. ### Changes - `monai/bundle/scripts.py`: warning added in `create_workflow()`; docstrings on `load()`, `run()`, and `create_workflow()` updated to describe the risk and point at the advisory. - `tests/bundle/test_bundle_download.py`: `TestLoadWarnsOnConfigExecution` — default `load()` warns and still executes the config (no flag needed), explicit `model=` still skips config parsing entirely (and warns about nothing), and `run()` warns via the same `create_workflow()` path. ## Test plan - [x] `python3 -m unittest tests.bundle.test_bundle_download.TestLoadWarnsOnConfigExecution -v` - [x] Full `tests/bundle/test_bundle_download.py`, `tests/bundle/test_config_parser.py` — no new failures vs. `dev` (remaining failures are pre-existing environment gaps: missing `requests`/`nibabel`, one `pdb`/`bdb` quirk) 🤖 Generated with [Claude Code](https://claude.com/claude-code) --------- Signed-off-by: R.

A script `print_dependencies.py` is provided to reconstruct a requirements file from the toml file when needed, such as installing dependencies before installing MONAI for technical reasons. Highlights: * Move everything build related into `pyproject.toml`. * Remove the requirements file and the `setup.cfg` file. * Add a script to recreate the requirements files if needed. * Update the version of Versioneer used. * Update actions to use the new installation process in a uniform manner. * Update the Docker files to use the process. * Update installation docs to reflect these changes and clarify some parts. * Adds a test in packaging for uv. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [ ] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. - [x] Documentation updated, tested `make html` command in the `docs/` folder. --------- Signed-off-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> Co-authored-by: pre-commit-ci[bot] <66853113+pre-commit-ci[bot]@users.noreply.github.com> Co-authored-by: YunLiu <55491388+KumoLiu@users.noreply.github.com> --- .github/workflows/build_docs.yml | 2 + .github/workflows/cicd_tests.yml | 57 +- .github/workflows/codeql-analysis.yml | 4 +- .github/workflows/cron-ngc-bundle.yml | 4 +- .github/workflows/cron.yml | 13 +- .github/workflows/docker.yml | 2 -

Installing a broken/hanging onnx (e.g. `onnx==1.18.0` on Windows) makes `import monai` fail with no error message. Root cause: `monai/networks/utils.py` and `monai/bundle/scripts.py` call `optional_import("onnx")` (and `onnx.reference` / `onnxruntime`) at module scope. `optional_import` imports eagerly (`__import__`), and `import monai` auto-loads `monai.networks`, so importing MONAI unconditionally imports onnx — inheriting any onnx import failure/hang. This defers those optional imports into the functions that actually use them (`convert_to_onnx` in `networks/utils.py`, `onnx_export`'s `save_onnx` in `bundle/scripts.py`), matching the lazy pattern already used for `tensorrt` in the same file. After this change, importing MONAI no longer imports onnx; the ONNX conversion code paths are unchanged. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. ### Testing Added `tests/networks/test_lazy_onnx_import.py`, which (in a subprocess, with a meta-path recorder) asserts that `import monai` and `import monai.bundle` do not import onnx/onnxruntime — verified passing with onnx installed. The existing `tests/networks/test_convert_to_onnx.py` continues to exercise the conversion paths in CI.

The cause was in `normalize_tensor`, where `eps` was added *after* the square root — this guarded the forward division but not the `sqrt` gradient, so a zero feature norm produced `1/(2·√0) = inf → NaN` during backprop. This PR moves `eps` inside the sqrt (`sqrt(sum(x**2) + eps)`), keeping the forward output unchanged for normal inputs while ensuring the gradient stays finite. This matches the standard LPIPS normalization pattern. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder.

The fallback then looks `x` up as a **dict attribute** rather than a key, and dot-notation fails on a value that bracket-notation returns happily: ```python parser = ConfigParser(config={"target": {"x": 1, "y": 2}, "alias": "$@target"}, globals={"monai": "monai"}) parser.alias["x"] # -> 1 parser.alias.x # -> AttributeError: 'dict' object has no attribute 'x' ``` This also affects chained refs (`"alias": "$@mid"`, `"mid": "$@target"`). Ref-backed proxies are already treated as first-class elsewhere: `_backing_id()` resolves the full `$@ref` chain for writes, and `test_ref_backed_proxy_write_through` covers `parser.alias["x"]` reads and writes. The dot-notation read is the one path that was not covered, and it diverges. It also contradicts the documented precedence rule on the class ("Config keys take precedence over `dict`/`list` attributes and methods") — here `x` *is* a key of the aliased node, but the dict attribute lookup wins and raises. ### Proposed changes Make `__getattr__`'s fallback mirror the one `__getitem__` already uses: if the chained id is absent but the key exists in the underlying container, return `self._value[key]`. Keys that are *not* in the container still fall through to `getattr`, so container methods (`.keys()`, `.items()`, …) are unaffected, as is the existing "config key shadows a same-named dict method" behaviour. The change is confined to the `except KeyError` fallback, so any id that resolves today keeps resolving through `_chain` exactly as before — no behaviour change for non-ref proxies. ### How did you test it? - Added `test_ref_backed_proxy_attribute_read` and `test_chained_ref_backed_proxy_attribute_read` next to the existing ref write-through tests. Both **fail without the source change** (`AttributeError`) and pass with it; they assert `parser.alias.x == parser.alias["x"]`, and that `.keys()` still resolves. - `tests/bundle/test_config_parser.py`: 34 passed before, 36 passed after (2 new), no regressions. - Whole `tests/bundle/` suite: identical results before and after the change (the only failures are pre-existing network-dependent `test_bundle_download` cases, unchanged by this PR). - `ruff check` / `ruff format --check` (repo-pinned 0.15.20), `black`, `isort` clean on both files; `mypy monai/bundle/config_parser.py` reports the same single pre-existing `yaml.safe_dump` error as `dev`, no new ones. ### Notes for the reviewer The fallback returns the raw value, matching `__getitem__`'s fallback rather than wrapping it in a new proxy — this keeps the two notations exactly consistent and the change minimal. Happy to wrap the result in `_wrap_parsed` instead if you'd prefer deeper dot-chaining through refs, though that would make dot- and bracket-notation diverge again in the other direction. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [x] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`.

Since mlflow>=3.13 hard-errors on the filesystem tracking backend, `MLFlowHandler` now defaults to a local SQLite backend (`sqlite:////mlruns.db`, artifacts under `/mlruns`) and rejects explicit local-path / `file://` tracking URIs with an actionable error. Adds `monai.utils.path_to_sqlite_uri`, an `artifact_location` argument, and SQLite engine disposal on `close()`. | | `transformers` | Bumped floor to `>=5.5.0`, closing two HIGH severity CVEs. `MultiModal` now builds a real `transformers.BertConfig` with `_attn_implementation="eager"` for transformers>=4.48's attention dispatch. | | `setuptools` | Bumped the build-system floor to `>=78.1.1`, closing one HIGH severity CVE. The old `<=79.0.1` cap (#8439) is no longer needed since the legacy `fetch_build_eggs` CLI usage is gone from `setup.py`. | This PR supersedes #8894 (the standalone SQLite migration), which I have proposed closing. ### Test plan - `tests/handlers/test_handler_mlflow.py` — SQLite default, artifact co-location, file-store rejection, remote URI, and a full run flow. - `tests/fl/monai_algo/test_fl_monai_algo.py` and `tests/integration/test_integration_bundle_run.py` — updated to SQLite tracking URIs. - `tests/networks/nets/test_transchex.py` — passes against transformers 4.36-4.40 and 5.5+. - `tests/utils/misc/test_monai_utils_misc.py::TestPathToSqliteUri` — SQLite URI construction and escaping. ### Please re-verify before merging The `transformers>=5.5.0` bump: the original `<5.0` cap (#8912) cited `torch.float8_e8m0fnu` missing from the NGC Docker image's PyTorch 2.7 build. This was not reproducible against PyPI `torch>=2.8.0`, but please re-run the Docker/tutorial CI against the current NGC base image. --------- Signed-off-by: R.

Because FL tasks are dispatched per round and executed with no human in the loop, a malicious or compromised server gets silent code execution on every participating client. The `UserWarning` added in #9057 for GHSA-873f-pvrv-4x83 lives in `create_workflow()`. This path never calls it — `MonaiAlgo` constructs `ConfigWorkflow` directly — so nothing warned here at all. ### Design Executing the config stays unblocked, for the same reason the `trust_remote_code` flag was dropped from #9057: MONAI has no mechanism to establish whether a bundle is trustworthy, so a flag mostly teaches operators to set it once and forget about it. Both `initialize()` methods now warn, naming the trust boundary (`extra[APP_ROOT]`) and the absence of per-round human interaction. The one behaviour change is narrowly scoped, and it targets the sink with no functional role in FL. `ConfigWorkflow` defaults `logging_file` to the bundle's own `configs/logging.conf` and passes it to `logging.config.fileConfig`, which `eval()`s the INI's `class=`/`args=` fields. That is code execution at construction time, before any config is parsed, and it hides in a plain INI rather than the MONAI `$`-DSL — easy to miss when reviewing a bundle. The FL client now treats `extra[ExtraItems.LOGGING_FILE]` as `False` both when the key is absent and when it is explicitly `None`, so a server-written `logging.conf` is never applied. `None` needs the same treatment as absent because it was the pre-PR default and `ConfigWorkflow` reads it as "fall back to the bundle's own `configs/logging.conf`" — exactly the file this change exists to keep away from `fileConfig`. An FL system that wants bundle logging passes an explicit path, through the key that already exists for it. The `fileConfig` warning sits inside the branch that actually calls it, not at the top of `__init__`. That keeps it truthful (nothing runs when the file is absent or logging is disabled, both common) and avoids double-warning callers who already got the `create_workflow()` warning, which is about `_target_`/`$` rather than the INI. ### Changes - `monai/fl/client/monai_algo.py`: warning in both `initialize()` methods; `ExtraItems.LOGGING_FILE` treated as `False` when absent or explicitly `None`; security notes on both class docstrings; both `initialize()` docstrings rewritten for the new default (this also fixes a `diable` typo). - `monai/bundle/workflows.py`: `_warn_logging_file_execution()` called immediately before each of the two `fileConfig` invocations; `logging_file` docstring entries updated on `BundleWorkflow`, `PythonicWorkflow` and `ConfigWorkflow`. - `tests/fl/monai_algo/test_fl_monai_algo.py`: `TestFLMonaiAlgoWarnsOnProvisionedConfig` — stages an app whose `train.json` and `logging.conf` each drop a distinct marker, for both `MonaiAlgo` and `MonaiAlgoStats`. Asserts the config still executes with the advisory warning; that the server's `logging.conf` no longer does, whether the key is absent or explicitly `None`; that an explicit path opts back in; and that no `fileConfig` warning fires when nothing is executed. - `tests/bundle/test_bundle_workflow.py`: `TestConfigWorkflowWarnsOnLoggingConf` — a bundle's default `configs/logging.conf` warns and still applies; `logging_file=False` neither warns nor applies it. Both new test classes snapshot and restore the root logger, closing any handler `fileConfig` installs. The suite runs in one process, so without that they would leak a root handler and formatter into every test that follows. ## Test plan - [x] `python -m unittest tests.fl.monai_algo.test_fl_monai_algo` — 17 passed - [x] `python -m unittest tests.fl.test_fl_monai_algo_stats` — 3 passed - [x] `python -m unittest tests.bundle.test_bundle_workflow.TestConfigWorkflowWarnsOnLoggingConf` — 2 passed - [x] `python -m unittest tests.bundle.test_bundle_download.TestLoadWarnsOnConfigExecution` — 6 passed, no double-warn regression on the #9057 fix - [x] Each new assertion checked against the unpatched code first — the advisory's payload writes its marker via the bundle config and via `logging.conf` before the change, and only via the bundle config after it - [x] Root logger verified identical before and after both new test classes run - [x] `black`, `isort`, `ruff` clean on the changed files ### Types of changes - [ ] Non-breaking change (fix or new feature that would not break existing functionality). - [x] Breaking change (fix or new feature that would cause existing functionality to change). - [x] New tests added to cover the changes. - [x] In-line docstrings updated. The breaking-change box is for the `LOGGING_FILE` default only: an FL deployment relying on the bundle shipping its own `logging.conf` now has to pass the path explicitly. Everything else is additive. --------- Signed-off-by: R.

This adds an opt-in use_flash_attention flag (default False, so existing behaviour is unchanged) that routes attention through torch.nn.functional.scaled_dot_product_attention, folding the relative position bias and, for shifted windows, the attention mask into one additive attn_mask cast to the query dtype. This mirrors the flash-attention option already in MONAI's SelfAttention, CrossAttention and CABlock. Measured on the SwinUNETR encoder (SwinViT) forward, inference, single GPU, best-of-5. Float32 output matches the default path to within 3e-6 and is bit-exact in float64, verified across 2D and 3D, batch sizes 1 to 4, and non-cubic inputs. | ROI | dtype | default | flash | speedup | |---|---|---|---|---| | 96^3 | fp32 | 12.59 ms | 8.34 ms | 1.51x | | 96^3 | bf16 | 10.71 ms | 5.46 ms | 1.96x | | 128^3 | fp32 | 34.27 ms | 21.74 ms | 1.58x | | 128^3 | bf16 | 29.45 ms | 14.12 ms | 2.09x | | 160^3 | fp32 | 59.05 ms | 37.66 ms | 1.57x | | 160^3 | bf16 | 51.25 ms | 25.33 ms | 2.02x | The flag is threaded through SwinTransformer, BasicLayer and SwinTransformerBlock to WindowAttention, exactly as use_v2 and use_checkpoint are. No parameters or buffers change, so pretrained weights load unchanged. The flash path is used only when autograd is disabled and the module is not scripted, so training and TorchScript keep the original path byte-for-byte; this is a deliberate choice to leave training numerics untouched. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [x] New tests added to cover the changes. - [x] In-line docstrings updated. --------- Signed-off-by: Soumya Snigdha Kundu Signed-off-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/networks/nets/swin_unetr.py | 36 ++++++++++++++++++++++++-- tests/networks/nets/test_swin_unetr.py | 13 ++++++++++ 2 files changed, 47 insertions(+), 2 deletions(-) diff --git a/monai/networks/nets/swin_unetr.py b/monai/networks/nets/swin_unetr.py index fa944b0920..7ab55ab396 100644 --- a/monai/networks/nets/swin_unetr.py +++ b/monai/networks/nets/swin_unetr.py @@ -98,6 +98,7 @@ def __init__( hyena_omega_0: float = 10.0, hyena_l_cache: int = 32, hyena_short_conv_fft_chunks: int = 0, + use_flash_attention: bool = False, ) -> None: """ Args: @@ -149,6 +150,7 @@ def __init__( hyena_omega_0: SIREN frequency.

It fails in `Crop.compute_slices` with `The tensor has a non-zero number of elements, but its data is not allocated yet`. The cause is that `compute_slices` ran its start/end math through CPU tensors (`convert_to_tensor(..., device="cpu")`). For `CenterSpatialCrop` the ROI values come from the input shape, so under tracing they're fake tensors with no storage, and moving them to the CPU asks Dynamo for data that isn't there. Since it's just integer math, I moved it to plain Python. A small `_to_int_list` helper handles the input forms (scalar, sequence, tensor, ndarray), with the same clamping and broadcasting as before. `CenterSpatialCrop` now compiles like the rest of the transforms. Added a regression test that compiles `CenterSpatialCrop` and checks the shape (fails before, passes after), guarded for PyTorch versions with `torch.compile`. Fixes #8191. --------- Signed-off-by: Soumya Snigdha Kundu Signed-off-by: Soumya Snigdha Kundu Co-authored-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- monai/transforms/croppad/array.py | 41 ++++++++++++-------- tests/transforms/test_center_spatial_crop.py | 25 ++++++++++++ 2 files changed, 50 insertions(+), 16 deletions(-) diff --git a/monai/transforms/croppad/array.py b/monai/transforms/croppad/array.py index 96175a1499..fc913fa767 100644 --- a/monai/transforms/croppad/array.py +++ b/monai/transforms/croppad/array.py @@ -342,6 +342,24 @@ def compute_pad_width(self, spatial_shape: Sequence[int]) -> tuple[tuple[int, in return spatial_pad.compute_pad_width(spatial_shape) +def _to_int_list(data: Sequence[int] | int | NdarrayOrTensor) -> list[int]: + """Coerce an ROI spec (scalar, sequence, tensor or ndarray) to a list of Python ints.""" + if isinstance(data, (str, bytes)): + raise TypeError("ROI specs must be integers or sequences of integers, not strings.") + return [int(i) for i in ensure_tuple(data)] + + +def _broadcast_int_pair( + a: Sequence[int] | int | NdarrayOrTensor, b: Sequence[int] | int | NdarrayOrTensor +) -> tuple[list[int], list[int]]: + """Coerce a pair of ROI specs to two equal-length int lists, broadcasting a scalar to match.""" + list_a, list_b = _to_int_list(a), _to_int_list(b) + n = max(len(list_a), len(list_b)) + if len(list_a) not in (1, n) or len(list_b) not in (1, n): + raise ValueError(f"ROI specs must have matching lengths or be scalar, got {len(list_a)} and {len(list_b)}.") + return (list_a * n if len(list_a) == 1 else list_a), (list_b * n if len(list_b) == 1 else list_b) + + class Crop(InvertibleTransform, LazyTransform): """ Perform crop operations on the input image. @@ -379,31 +397,22 @@ def compute_slices( roi_slices: list of slices for each of the spatial dimensions.

This should fix formatting in the same way as `runtests.sh --autofix` but automatically, and before other actions run for too long in a PR. Note that the versions of both need to be set in the `.pre-commit-config.yaml` file separately from wherever else they're specified, so when versions are changed they need to be synced between files. The version for isort is left unchanged but the `<6` restriction should be removed shortly. The pre-commit step for `pycln` was removed in favour of checking for unused imports with Ruff by enabling F401 in `pyproject.toml`. ### Types of changes - [x] Non-breaking change (fix or new feature that would not break existing functionality). - [ ] Breaking change (fix or new feature that would cause existing functionality to change). - [ ] New tests added to cover the changes. - [ ] Integration tests passed locally by running `./runtests.sh -f -u --net --coverage`. - [ ] Quick tests passed locally by running `./runtests.sh --quick --unittests --disttests`. - [ ] In-line docstrings updated. - [ ] Documentation updated, tested `make html` command in the `docs/` folder. --------- Signed-off-by: Eric Kerfoot <17726042+ericspod@users.noreply.github.com> --- .pre-commit-config.yaml | 30 ++++++++++++++++++---- pyproject.toml | 56 ++++++++++++++++++++--------------------- runtests.sh | 2 +- 3 files changed, 53 insertions(+), 35 deletions(-) diff --git a/.pre-commit-config.yaml b/.pre-commit-config.yaml index 2d78b08041..ae03b5bae9 100644 --- a/.pre-commit-config.yaml +++ b/.pre-commit-config.yaml @@ -13,11 +13,13 @@ repos: hooks: - id: end-of-file-fixer - id: trailing-whitespace + - id: check-ast - id: check-yaml - id: check-docstring-first - id: check-executables-have-shebangs - id: check-toml - id: check-case-conflict + - id: check-illegal-windows-names - id: check-added-large-files args: ['--maxkb=1024'] - id: detect-private-key @@ -26,8 +28,9 @@ repos: args: ['--autofix', '--no-sort-keys', '--indent=4'] - id: end-of-file-fixer - id: mixed-line-ending + - repo: https://github.com/astral-sh/ruff-pre-commit - rev: v0.15.20 + rev: v0.16.5 hooks: - id: ruff-check args: ["--fix"] @@ -37,8 +40,25 @@ repos: ^monai/_version.py ) - - repo: https://github.com/hadialqattan/pycln - rev: v2.6.0 + - repo: https://github.com/psf/black-pre-commit-mirror + rev: 26.5.1 # Black version, keep synced with MONAI requirements hooks: - - id: pycln - args: [--config=pyproject.toml] + - id: black + language_version: python3 + # black will be given individual file names and so will ignore the excludes in pyproject.toml + exclude: | + (?x)( + ^versioneer.py| + ^monai/_version.py + ) + + - repo: https://github.com/pycqa/isort + rev: 9.0.1 # isort version, keep synced with MONAI requirements + hooks: + - id: isort + name: isort (python) + exclude: | + (?x)( + ^versioneer.py| + ^monai/_version.py + ) diff --git a/pyproject.toml b/pyproject.toml index fcd57adac5..684d905002 100644 --- a/pyproject.toml +++ b/pyproject.toml @@ -130,7 +130,8 @@ mlflow = ["mlflow>=3.15.2"] nibabel = ["nibabel"] nni = [ "nni;

Pass `weights_only=True` to pretrained weight loaders in `senet`, `densenet`, `efficientnet`, and `text_embedding` so a substituted `.pth` cannot unpickle code (GHSA-vm9c-7j6g-c7mm). - `check_hash`: emit a `UserWarning` when no hash value is provided instead of silently passing, and default `check_hash`/`download_url` to `sha256` (GHSA-hhh4-h52m-fqh6). - `download_large_files`: confine large-file targets to the bundle directory, rejecting absolute and `../` traversal (GHSA-x4pc-gj5h-3pq7). Note: SENet pretrained URLs remain `http://` because the upstream host does not serve the files over HTTPS (verified unreachable); `weights_only=True` closes the code-execution vector, leaving only a transport-integrity gap. ### Types of changes - [ ] Non-breaking change - [x] Breaking change (default hash type changes from md5 to sha256 for `check_hash`/`download_url`; callers that relied on the md5 default now pass `hash_type` explicitly) - [x] New tests added to cover the changes. --------- Signed-off-by: R.
