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

TL;DR

The test test_wrapper_subclass_aliasing_out_op_cpu in test_python_dispatch.py is failing intermittently and has been disabled in CI, requiring investigation and potential fixes to resolve the flakiness.

Guidance

• Investigate the workflow logs linked in the issue to identify patterns or commonalities among the 36 failures and 18 successes of the test over the past 6 hours.
• Follow the provided debugging instructions to find relevant log snippets by grepping for test_wrapper_subclass_aliasing_out_op_cpu in the expanded Test step of the job.
• Review the test code in test_python_dispatch.py to understand its logic and potential sources of flakiness, such as dependencies on external factors or race conditions.
• Consider re-enabling the test in CI with additional logging or debugging statements to gather more information about the failures.

Notes

The issue lacks specific technical details about the test or its failures, making it challenging to provide a precise fix or workaround. Further investigation and analysis of the logs and test code are necessary to determine the root cause of the flakiness.

Recommendation

Apply workaround: Temporarily re-enable the test with additional logging to gather more information about the failures, as the root cause of the flakiness is not yet understood.
