Root Cause

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

Platforms: linux, slow

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 6 workflow(s) with 12 failures and 6 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_grad_has_aux
  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_compiled_autograd.py

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

extent analysis

TL;DR

The test test_grad_has_aux in inductor/test_compiled_autograd.py is failing intermittently in CI, and debugging is required to identify the root cause.

Guidance

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

Notes

The issue is specific to the Linux platform and has been observed in multiple workflow runs, indicating a potential environmental or test-specific issue.

Recommendation

Apply workaround: temporarily enable the test and run it locally to reproduce the issue and gather more information, as the CI logs may not provide enough context due to the shielding of flaky tests.
