Note that we fixed these before by adding None checks before instead of checking the optimize flag: #76619
Also this file is not imported when PyTorch is imported? There should have a been a test to detect that!

@albanD thanks for the feedback. Added it to the test and use is None check, which is more Pythonic than sys.flags.optimize < 2

Thanks for the update!
