# Moving to the GPU is a single token, `:gpu`, which auto-completes to `(:collocation, :exa, :madnlp, :gpu)`. It requires the `:exa` modeler (hence `@def`, not the macro-free API — cf. the definition section) plus a CUDA-capable GPU.
#
# In a seminar or on Binder there is usually **no functional GPU**, so the call is *expected to fail* — that is the pedagogical point: the `:gpu` token needs a specific setup. We wrap it in a `try/catch` so the tour keeps running and shows the raised exception.
#
# The GPU stack is armed by **three** loads, not two: `MadNLPGPU`, `CUDA` and `CUDSS`. Miss the third and the failure you get is a missing package, not a missing device.
