The utils.nullcontext() appears in line 257 of the script train.py. But I can't find the definition. What is this? I would appreciate it if you could get back to me!

Hi,

Oops, sorry, I forgot to include this function after refactoring the code. It should be like this:

from contextlib import contextmanager

@contextmanager
def nullcontext(enter_result=None):
    yield enter_result

Now it's fixed in https://github.com/tml-epfl/understanding-fast-adv-training/commit/ceed49440bfc35a676375b783eaba5940e583bcc. Thanks for letting us know about the problem!

Best, Maksym
