@pytorchbot merge -f "ci failures are irrelevant"

[pytorchmergebot]

@pytorchbot successfully started a merge job. Check the current status here.
The merge job was triggered with the force (-f) flag. This means your change will be merged immediately, bypassing any CI checks (ETA: 1-5 minutes). If this is not the intended behavior, feel free to use some of the other merge options in the wiki.
Please reach out to the PyTorch DevX Team with feedback or questions!

Hey @ezyang.
You've committed this PR, but it does not have both a 'release notes: ...' and 'topics: ...' label. Please add one of each to the PR. The 'release notes: ...' label should represent the part of PyTorch that this PR changes (fx, autograd, distributed, etc) and the 'topics: ...' label should represent the kind of PR it is (not user facing, new feature, bug fix, perf improvement, etc). The list of valid labels can be found here for the 'release notes: ...' and here for the 'topics: ...'.
For changes that are 'topic: not user facing' there is no need for a release notes label.

Failure is fairly benign but don't know why we didn't catch this in OSS:

stderr: **redacted**/aten/src/ATen/native/metal/mpscnn/MPSImageWrapper.mm:26:10: error: ARC forbids explicit message send of 'dealloc'
