TypeError(('TensorType does not support iteration. '

[homink]

Hello

I am new to machine learning and love to experiment deepspeech. Thanks for letting me use this. I have encountered the following error and would like ask some help.

I have installed all dependencies and have switched to the Theano backend. Nothing more than these has been changed nor configured. I found that the type running in the iteration loop of _tensor_py_operatiors is <class 'theano.tensor.sharedvar.TensorSharedVariable'>. I have no idea why this is not <class 'theano.tensor.var.TensorVariable'>. Could anyone take a look?

Thanks in advance,

The following helped me out. :)

pip install Keras==1.1.0
