How about us add some more testing data? for example: ```python def verify_fused_batch_norm(shape): .... def test_fused_batch_norm(): verify_fused_batch_norm(shape=(1, 12, 12, 32)) verify_fused_batch_norm(shape=(1, 24, 24, 64)) ... if __name__ == "__main__": test_fused_batch_norm() ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
