Ignore cudf's __dataframe__ deprecation.

[bdice]

Currently CI is failing due to rapidsai/cudf#17736.

The __dataframe__ protocol appears to be used internally by scikit-learn: https://github.com/scikit-learn/scikit-learn/blob/311bf6badd74bb69081eb90e2643f15706d3473c/sklearn/utils/validation.py#L389

Errors look like:

FAILED test_metrics.py::test_sklearn_search - FutureWarning: Using `__dataframe__` is deprecated

This PR ignores the FutureWarning to allow CI to pass.

Help on this PR is welcome! Please feel free to push if you can fix any of the remaining test failures.

This makes sure we only ignore the dataframe warning and not all FutureWarnings. Also remvose the need for the comment I'd say

Suggested change

	@pytest.mark.filterwarnings("ignore::FutureWarning")
	@pytest.mark.filterwarnings("ignore:Support for loading dataframes via the `__dataframe__` interchange protocol is deprecated")

(same for the other occurrence)

Looking at the failed CI jobs I see a lot of:

ConftestImportFailure: FutureWarning: The `rmm._cuda.stream` module is deprecated in 25.02 and will be removed in a future release. Use `rmm.pylibrmm.stream` instead. (from /__w/cuml/cuml/python/cuml/cuml/tests/conftest.py)

Which makes me think that somewhere in strings_udf.pyx there is an old import. However looking at https://github.com/rapidsai/cudf/blob/a4bbd0930a0e4922f69586560b064a0bd9e6aedc/python/cudf/cudf/_lib/strings_udf.pyx I can't immediately see it and the last edit is a few days ago. Maybe compiling locally with more debugging turned on so we can see which line in strings_udf.pyx is causing this can shed light on this

rapidsai/rmm#1775 would cause this warning, but we searched the RAPIDS code base extensively to make sure there were no internal uses of this that would trigger deprecations... I am looking now to see what we might have missed.

[bdice]

I still don't see anything and can't reproduce locally. I am trying to rerun.

[Matt711]

I'm taking a look too.

Seems like rerunning CI has fixed the problem. I suspect there was some intermediate state where the RMM PR had been merged but not all artifacts / dependencies agreed on how it was supposed to be used until the dependency tree (notably cudf) was rebuilt? Not sure.
