Fix Plan

The fix involves lowering the tolerances in the test_remove_no_ops test to account for the differences introduced by enabling native_matmul with torch._inductor.config.native_matmul.

Step-by-Step Solution

• Identify the test file containing test_remove_no_ops and locate the assertions that check for tensor equality.
• Lower the tolerances in these assertions by using the torch.testing.assert_close function with a smaller rtol and atol value.
• Example code:

import torch

# Before
self.assertEqual(tensor1, tensor2)

# After
torch.testing.assert_close(tensor1, tensor2, rtol=1e-4, atol=1e-5)

• Update the test to use the new tolerance values and verify that the test passes with native_matmul enabled.

Verification

• Run the updated test with native_matmul enabled and verify that it passes.
• Check that the resulting tensors are still correct and unchanged by the operations being performed.

Extra Tips

• Be cautious when lowering tolerances, as it may mask other issues in the code.
• Consider adding additional tests to verify the correctness of the operations being performed.
