This failure in CI appears suddenly without any code changes to related files. It is likely due to different test case run order. The test code was badly written such that test class TestModels_new_jit_API, if called first, will assign TestModels.onnx_shape_inference = True, circumventing this problem. On the other hand, if TestModels is called first, AttributeError will be raised. Should be fixed by #72350.
