ValueError: None values not supported. On executing the main.py file, i'm getting the following error:

• If you think the result is wrong - what result did you expect instead?
• How to reproduce the issue?
• Provide all necessary data

never tried it with TF 1.0 - I tested it with TF 1.3 So the first thing I would try is to switch to 1.3 and see what happens.
