Problem with "tensorflow_backend" #2

I get the below massage when I try to run model_message.py for subtask A;

Traceback

I wonder if you help me with this problem!

cbaziotis commented 7 years ago

The issue has to do with K.dot and Tensorflow backend. I pushed a fix. Run:

pip install keras-utilities -U

Let me know if this fixes the issue.

Lastly, i want to note that the project was developed using Theano as a backend and i suggest that you switch to Theano, as it has better RNN performance.

pip install keras-utilities -U solved the problem thanks.
