ebafd2aa - Stop warning on .names() access in max_pool2d and max_pool2d_backward (#60059)

Stop warning on .names() access in max_pool2d and max_pool2d_backward (#60059) Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/60059 Fixes #60053. The problem is that `.names()` always triggers the named tensor warning. To not trigger it, one has to guard it with has_names: `x.has_names() ? x.names() : DimnameList{}` This is not the first time this has happened; we should probably make it so that .names() doesn't raise a warning unless it is actually populated with names. That's a little tricky to implement so I'm leaving it for the future. Test Plan: - New test, also run `python test/test_nn.py -v -k "max_pool"` and confirm there are no warnings.
