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

TL;DR

The test test_retain_grad_inside_transform_cpu in functorch/test_eager_transforms.py is failing intermittently in CI and needs to be debugged by analyzing the workflow logs.

Guidance

• To debug the issue, follow the provided debugging instructions: click on the recent samples link, expand the Test step in the workflow logs, and grep for test_retain_grad_inside_transform_cpu to find relevant log snippets.
• Study the logs from multiple instances of the test run to identify patterns or common errors that may be causing the flakiness.
• Check the test file functorch/test_eager_transforms.py for any potential issues or recent changes that could be contributing to the failures.
• Review the list of disabled tests at https://hud.pytorch.org/disabled to see if there are any other related issues or tests that may be relevant to this problem.

Notes

The debugging process may require careful analysis of the logs and test code to identify the root cause of the issue, and it's possible that the fix may involve modifying the test or the underlying code.

Recommendation

Apply workaround: temporarily enable the test and run it locally or in a controlled environment to gather more information and reproduce the issue, which can help in identifying the root cause and developing a fix.
