Root Cause

This test was disabled because it is failing on main branch (recent examples).

extent analysis

TL;DR

Enable the disabled test test_c10d_nccl.py and investigate the failure cause on the main branch.

Guidance

  • Investigate the recent examples of test failures on torch-ci.com to understand the failure patterns.
  • Review the test_c10d_nccl.py test code, specifically the ProcessGroupNCCLGroupTest and test_resume test case, to identify potential issues.
  • Check the test environment and configuration on the main branch to ensure it matches the expected setup.
  • Consider re-enabling the test and running it locally or on a CI environment to reproduce and debug the issue.

Notes

The issue lacks specific technical details about the failure, so a thorough investigation of the test code and environment is necessary to determine the root cause.

Recommendation

Apply workaround: Re-enable the test and investigate the failure cause, as the test was disabled due to failures on the main branch, and understanding the cause is essential to resolving the issue.
