It seems like you're experiencing an issue with weights reloading... Have you deleted the weights somehow? Maybe your OS requires a different paths for the weights / your python/tf install is kind of broken :(
In case that helps, my environment is

I am using Mac. The weights are there in the correspond directory. I am using python 3.6. Let me check with Python 3.6.4 and corresponding config.
