It would be nice to have a requirements.txt file for this project. The Keras and Lasagne APIs are constantly changing, and it seems that the current version of Keras on pip (Keras 0.3.2) doesn't work with this tutorial's code anymore.

For example, in FixedEmbedding.py, keras.utils.theano_utils no longer exists in Keras. A workaround to this issue is here.

Dear Nils,
First of all thanks a lot for the great tutorial. I'm learning a lot watching your videos and reading through your code.
I naively wanted to run our implementation of the SENNA model with Keras and cannot make it work even after trying many things and spending of lot of time on forums dedicated to Theano and Keras.
For the record, I think it has something to do with The FixEmbedding layer and/or my version of Keras==1.0.3. I'm running Python 3.5 but I fixed all print and unicode trivial issues in the code so it should not be a pb with compatibility with Python 3.

Here is the traceback:

Traceback (most recent call last):

Thanks for your help.
