test_dataframe_shuffle: (CuPy's?) CUB emits warning: cuda_runtime_api.h [jitify] File not found

[jakirkham]

Am seeing the following warning on CI

tests/test_explicit_comms.py::test_dataframe_shuffle[True-tcp-cudf-1] cub/detail/detect_cuda_runtime.cuh(39): warning: cuda_runtime_api.h: [jitify] File not found
../util_type.cuh(42): warning: cuda.h: [jitify] File not found
cupy_jitify_exercise(10): warning: cooperative_groups.h: [jitify] File not found
cupy_jitify_exercise(11): warning: cooperative_groups/memcpy_async.h: [jitify] File not found
PASSED

It looks like this may be related to how CuPy uses CUB. Though it could easily be something else

Note: The test does pass. However the warning looks odd. Like something is misconfigured

As pointed out by @leofang offline, this looks similar to this SO question

[leofang]

The noise should be suppressed by cupy/cupy#8235 and will be available starting CuPy v13.1.0. Question: Is this something that dask-cuda CI can help validate?

Thanks for the heads up @leofang !

We can do a human validation when 13.1.0 is out, we don't make any automatic warning validation because several exist from Dask, which are also not suppressed to support debugging when something goes wrong.
