Root Cause

  • Flaky test
  • Can reproduce locally
  • Caused by external libraries (e.g. bug in transformers)

Name of failing test

pytest -s -v tests/compile/passes --ignore tests/compile/passes/distributed

Basic information

  • Flaky test
  • Can reproduce locally
  • Caused by external libraries (e.g. bug in transformers)

🧪 Describe the failing test

This is a new test group that we are trying to enable. There are a lot of failures there, most of them related to silu, rmsnorm, and rope.

I know you have been working on fusions, is this TG supposed to be in your TODO list, or we should go ahead and triage it?

Fix Plan

The fix involves updating the test group to handle silu, rmsnorm, and rope failures.

  • Identify and update the failing test cases:
    • Check the test files in tests/compile/passes for silu, rmsnorm, and rope related tests.
    • Update the test cases to correctly handle these operations.
  • Example code snippet to update a test case:
import pytest

@pytest.mark.parametrize("operation", ["silu", "rmsnorm", "rope"])
def test_compile_passes(operation):
    # Update the test logic to handle the operation
    if operation == "silu":
        # Add silu specific test logic
        pass
    elif operation == "rmsnorm":
        # Add rmsnorm specific test logic
        pass
    elif operation == "rope":
        # Add rope specific test logic
        pass
    # Rest of the test logic
  • Run the updated test group to verify the fixes:
    • Use the command pytest -s -v tests/compile/passes --ignore tests/compile/passes/distributed

Verification

To verify the fix, run the test group and check for any remaining failures.

Extra Tips

  • Make sure to update the test cases to handle any edge cases for silu, rmsnorm, and rope operations.
  • If the failures persist, try to isolate the issue by running individual test cases.
