"TypeError: TensorType does not support iteration." error while running train.py

Hi,

I am training the model with keras 1.2 version and Theano 0.8.2 version and I am getting the following error.

Can you please help me in solving this error.

TypeError: TensorType does not support iteration. Maybe you are using builtin.sum instead of theano.tensor.sum? (Maybe .max?)

Probably a duplicate of #12 . The solution was: pip install Keras==1.1.0
