"""This module exists since the `torch.testing` exposed a lot of stuff that shouldn't have been public. Although this
was never documented anywhere, some other internal FB projects as well as downstream OSS projects might use this. Thus,
we don't internalize without warning, but still go through a deprecation cycle.
