Root Cause

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

RAW_BUFFERClick to expand / collapse

Platforms: asan, linux

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 19 workflow(s) with 38 failures and 19 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_opcheck_opinfo_NumpySortCustomOp_cpu_float32
  4. There should be several instances run (as flaky tests are rerun in CI) from which you can study the logs.

Test file path: test_custom_ops.py

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

extent analysis

TL;DR

  • Investigate and address the flakiness of the test_opcheck_opinfo_NumpySortCustomOp_cpu_float32 test in the test_custom_ops.py file.

Guidance

  • Review the provided recent examples and workflow logs to understand the test failures.
  • Follow the Debugging instructions to find relevant log snippets and study the logs for the test_opcheck_opinfo_NumpySortCustomOp_cpu_float32 test.
  • Analyze the test file test_custom_ops.py to identify potential causes of the flakiness.
  • Consider re-enabling the test and running it locally to reproduce and debug the issue.

Example

  • No specific code snippet is provided due to the lack of detailed information about the test implementation.

Notes

  • The issue is related to a flaky test, which may be caused by various factors such as environmental conditions, test dependencies, or test implementation.
  • The provided debugging instructions and logs should help identify the root cause of the issue.

Recommendation

  • Apply workaround: Investigate and address the flakiness of the test to prevent it from causing CI failures and to ensure the reliability of the test suite.
  • Reason: The test is currently disabled due to its flakiness, and addressing the issue will help maintain the overall quality and stability of the project.
