my environment is Theano (1.0.1) , Keras (2.1.1) ubuntu 16.04, here is the specific error
Traceback (most recent call last):

Thanks a lot , I solved it, after reading your code, I have a problem, Here is the specific description .

The weight matrix Wu(1) is the same for all user? is it right ? Thank you very much!

[librahu]

Yes, this expression may be confusing. The meaning of W_u^(1) is that the weight matrix of first layer for user, not for specific user u.
