Pull request overview
This PR adds a conditional skip decorator to the TestGQARegressions test class to prevent FlashAttention regression tests from running when FlashAttention is not available on the system. This helps unblock CI build pipelines that may not have the necessary CUDA support or hardware requirements.
Changes:
- Added
@unittest.skipIfdecorator toTestGQARegressionsclass to skip tests when FlashAttention is unavailable
