Root Cause

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

extent analysis

TL;DR

  • Re-enable and re-run the disabled test test_lazy_compile_kernel_name_collision_across_modules in test_gpu_cpp_wrapper.py to assess if the issue persists.

Guidance

  • Review the recent failure examples on torch-ci.com to understand the nature of the test failures.
  • Investigate potential kernel name collisions across modules that could be causing the test to fail.
  • Consider updating the test or the kernel naming strategy to prevent collisions.
  • Check if any recent changes in the main branch might be contributing to the test failure.

Notes

  • The issue seems to be related to a specific test failure on the main branch, and the cause is not explicitly stated.
  • Without more information about the test or the kernel naming strategy, it's difficult to provide a more specific solution.

Recommendation

  • Apply workaround: Re-enable the test and investigate the cause of the failure to determine the best course of action.

FAIL-SAFE: Given the lack of detailed information, the guidance provided is minimal and focused on investigating the issue further rather than applying a specific fix.
