tensorflow has no attribute GraphKeys

Hi, not urgent, but I am attempting to reproduce the results by running the 'run.sh' script and hitting the error 'tensorflow' has no attribute 'GraphKeys'.

I think this was handled in the quick_eval_cifar.py tensorflow.compat.v1 import but not in the clever_hans scripts from which the error originates. Not sure how to best proceed. Traceback as follows. Any help would be appreciated.

Traceback (most recent call last):
