AttributeError: 'module' object has no attribute '_VARSCOPE_KEY'

When I run the stageI/run_exp.py. I meet the problem as follows:
Traceback (most recent call last):

AttributeError: 'module' object has no attribute '_VARSCOPE_KEY'
Why ?
Maybe the number of lines are different to yours. Someone can help me? Thank you

I had a similar issue and solved it using pip install tensorflow==1.7.0. This is because of PrettyTensor incompatibility in some functions with Tensorflow's latest versions.

For more details: google/prettytensor#62

Let me know if it doesn't work.

Well, it still doesn't work for me. The error stays with tensorflow versions 1.7.0, 1.4.0, 1.0 and 0.12.

If you are using tensorflow 0.12 I had to downgrade PrettyTensor to version 0.7.1 from 0.7.4 to get it to run. pip install prettytensor==0.7.1

i am facing the same issue and cannot install tensorflow 1.7.0 on windows
