training error no attribute 'outbound_nodes'

[slajar]

I ran the training but it gives me the error below. Actually, I have tensorflow 1.13.1. Does this cause the issue? I had to change the requirements.txt file to get this running. If this may be the problem, I'll consider downgrading. Thanks for any help.

Hi @slajar,

The previous version of tensorflow was causing some issues.
I just update a new version of the project in commit e3f5eba.
I updated the packages (including tensorflow), the architecture and a lot of conceptual details that was wrong, but the performance is similar. Please check out and contact me if something goes wrong.

Cheers,
