pytorch - 💡(How to fix) Fix DISABLED test_transforms_dont_support_saved_tensor_hooks_transform_jacrev_cpu (__main__.TestComposabilityCPU) [2 comments, 1 participants]

TL;DR

The most likely fix involves investigating and addressing the flakiness in the test_transforms_dont_support_saved_tensor_hooks_transform_jacrev_cpu test by analyzing the workflow logs and debugging the test in functorch/test_eager_transforms.py.

Guidance

• Investigate the workflow logs by following the provided debugging instructions to identify patterns or clues that could explain the test flakiness.
• Focus on the test_transforms_dont_support_saved_tensor_hooks_transform_jacrev_cpu test in functorch/test_eager_transforms.py to understand the test's logic and potential failure points.
• Consider rerunning the test locally or in a controlled environment to reproduce and debug the issue.
• Review the test's dependencies and environment to ensure that there are no external factors contributing to the flakiness.

Notes

The provided information suggests that the test is flaky, but the root cause is unclear. Further investigation and debugging are necessary to determine the cause and develop a fix.

Recommendation

Apply workaround: Temporarily disable the flaky test or implement a retry mechanism to mitigate the issue until a permanent fix can be developed. This will allow the CI pipeline to proceed while the root cause is being investigated.
