hello, I tried to train your data with your code, I use the tensorflow as the backend and I meet a problem. how can i solve it? I’d like to receive your answer, thanks!

 raise TypeError("'Tensor' object is not iterable.")

Oh that should be an issue with the new keras version. Try downgrade the keras version to 1.0.1.

Yang507 commented 7 years ago

sorry, i've tried some methods but i didn't solve the keras' downgrade problem, could you give me some suggestions?my keras' version is 1.1.1, thank you!

Okay I'll look into this problem and get back after fixing it. A temporary solution is to comment those lines, which means opting out the batch normalization layers. That might lead to slower convergence or poorer optimum.

I used the keras version 1.0.4( https://testpypi.python.org/pypi/Keras) can run, the problem had been solved.

I just updated a version which supports the latest tensorflow and keras. However, it might not be able to run on the older version tensorflow and keras. The original implemenation is in branch old.
