Root Cause

This test was disabled because it is failing in CI. See recent examples and the most recent trunk workflow logs.

Platforms: inductor

This test was disabled because it is failing in CI. See recent examples and the most recent trunk workflow logs.

Over the past 6 hours, it has been determined flaky in 17 workflow(s) with 68 failures and 17 successes.

Debugging instructions (after clicking on the recent samples link): DO NOT ASSUME THINGS ARE OKAY IF THE CI IS GREEN. We now shield flaky tests from developers so CI will thus be green but it will be harder to parse the logs. To find relevant log snippets:

  1. Click on the workflow logs linked above
  2. Click on the Test step of the job so that it is expanded. Otherwise, the grepping will not work.
  3. Grep for test_template_epilogue_fusion_static_analysis_test_case_spills_reject_use_async_compile_False
  4. There should be several instances run (as flaky tests are rerun in CI) from which you can study the logs.

Test file path: inductor/test_max_autotune.py

For all disabled tests (by GitHub issue), see https://hud.pytorch.org/disabled.

extent analysis

TL;DR

The test test_template_epilogue_fusion_static_analysis_test_case_spills_reject_use_async_compile_False in inductor/test_max_autotune.py is failing intermittently and has been disabled, requiring investigation and potential fixes to stabilize it.

Guidance

  • Investigate the workflow logs linked in the issue to identify patterns or common errors in the failed test runs by following the provided debugging instructions.
  • Study the test file inductor/test_max_autotune.py to understand the test case test_template_epilogue_fusion_static_analysis_test_case_spills_reject_use_async_compile_False and potential reasons for its flakiness.
  • Check the list of disabled tests at https://hud.pytorch.org/disabled for any related issues or patterns that might help in resolving this test's flakiness.
  • Consider re-enabling the test temporarily in a controlled environment to gather more detailed logs or run it multiple times to observe if the failure is reproducible.

Notes

The issue lacks specific technical details about the failures, making it challenging to provide a direct fix. The debugging instructions and links to workflow logs are crucial for understanding the nature of the failures.

Recommendation

Apply workaround: Temporarily re-enable the test in a controlled environment to gather more detailed logs and run it multiple times to observe if the failure is reproducible, which can help in identifying the root cause.
