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

TL;DR

The test test_vmap_over_vmap_captured is failing intermittently in CI, and to fix it, we need to investigate the logs and identify the root cause of the flakiness.

Guidance

• To start debugging, follow the provided instructions to find relevant log snippets by clicking on the workflow logs, expanding the Test step, and grepping for test_vmap_over_vmap_captured.
• Study the logs from multiple instances of the test run to identify any patterns or common errors that may be causing the flakiness.
• Review the test file inductor/test_compiled_autograd.py to understand the test case and potential areas where the issue may be occurring.
• Check the list of disabled tests at https://hud.pytorch.org/disabled to see if there are any related issues or known problems that may be contributing to the flakiness.

Notes

The issue is specific to the Linux platform, and the test is failing intermittently, which suggests that the problem may be related to environmental or timing issues.

Recommendation

Apply workaround: Since the test is flaky and the CI is green, it's likely that the issue is not consistently reproducible, and a workaround may be necessary to stabilize the test. Further investigation is needed to determine the root cause and develop a permanent fix.
