Hi, first of all thanks for the implementation, very useful to understand the paper and compare with own implementation ! I have the following error in the training data. Can you help me to solve it? Thanks！

I can reproduce this error when I'm using tensorflow 1.0.0, but using tensorflow 1.4.0 and keras 2.1.1 it works for me. Try using a more recent version of keras and tensorflow and tell me how it goes.

Thank you very much for your answer. Through your hint, I've updated tensorflow 1.4.0, and now I can run this code. Then,I have a small request. Can you give me a look at your trained weight file? Because of the longer training time, I want to get into the next section of the code faster. Thank you again for your help.
