functorch 1.13 release tracker

[zou3519]

Here are the remaining items we should do before the PyTorch 1.13 release. Note that PyTorch 1.13 has cut a release branch, so if we are going to find bugs, we should find and fix them soon. The absolute deadline is 10/21.

P0

• AOTAutograd tutorial is broken. It doesn't run and appears to give silently incorrect results. @Chillee
• Functorch memory_efficient_fusion gives wrong output batch size pytorch#86020 @Chillee
• cross @samdow
• TorchBench microbenchmark regression suite, test new release for regressions @zou3519
• functorch 1.13 docs (this is separate from pytorch docs...) @zou3519
• PyTorch release notes and release blurb @zou3519
• check version numbers @zou3519
• Test functorch 1.13.0 pip binary (pip install functorch, see if torch of correct version gets installed) @zou3519
• Publish functorch 1.13.0 binary
• Publish functorch 1.13.0 release notes

P1 (Nice to have, especially if they catch critical bugs):

• Test functorch over torchbench models @kshitij12345 Tests do not need to go into the release; we should try to fix any hi-pri bugs we find as a result of this.
• Better contiguity testing in functorch opinfo testing #1029 . Tests do not need to go into the release; we should try to fix any hi-pri bugs we find as a result of this.
