Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/55385 This renames `assert_tensors_(equal|close)` to `_check_tensors_(equal|close)` and exposes two new functions: `assert_(equal|close)`. In addition to tensor pairs, the newly added functions also support the comparison of tensors in sequences or mappings. Otherwise their signature stays the same.
