What does this PR do?

Updates push_tests_mps to separate tests by category and fix some environment issues. For now a lot of failures are due to a problem with GitHub's runners so we also disable the workflow.

Who can review?

Anyone in the community is free to review the PR once the tests have passed. Feel free to tag
members/contributors who may be interested in your PR.

Does removing them help launch the tests? Could we maybe trigger it manually?

I don't know if we can trigger it manually. Currently the tests launch on push to main and eventually segfault after some scheduler tests

https://github.com/huggingface/diffusers/actions/runs/12588771861/job/35087350062#step:7:8211

Most pipeline tests seem to be failing and there are some warnings

There was a problem when trying to write in your cache folder (/System/Volumes/Data/mnt/cache/hub). You should set the environment variable TRANSFORMERS_CACHE to a writable directory.
There was a problem when trying to write in your cache folder (/System/Volumes/Data/mnt/cache/hub). Please, ensure the directory exists and can be written to.

It suggests some pipeline tests are failing because of it, but there are no tracebacks for individual test failures, probably due to the segfault.

Sorry should have been clearer.

What we could do to ensure the MPS stuff runs successfully:

  • Temporarily have a workflow in this PR with the same contents as the one in .github/workflows/push_tests_mps.yml.
  • Have the temporary workflow triggered on PRs so that we can verify it.
  • Once we confirm things are working as expected, we delete the temporary workflow.

Does this sound good?

Nice seems like the tests are getting picked up? We can let them run and fix anything in a follow-up PR? WDYT?

There are still some failures so far, I'll compare to one of the last runs to check if anything is fixed. I think priority is fixing the segfault but I see no indication of anything that could be causing it. We could separate the tests like models, pipelines, schedulers, might help break it down as there are a lot of FAILED and a lot of SKIPPED.

Makes sense and okay for me to tackle that in this PR. Thanks! Let me know if I can help.

Won't it cause any numerical problems or qualitative problems?

Should be ok but I'll cherry-pick this + the other fix (64553b3) and review with @yiyixuxu. Edit: this PR can replace the current mps workflow as discussed.

PR is now only workflow changes, we may want to just disable it until we get the new runner though.
