Fix Keras >0.3 compatibility

[sashank06]

Hi,
When I try to run the example.py file I run into this error.
from keras.models import Graph
ImportError: cannot import name Graph
I heard Keras removed Graph function. So is there any alternative to do this and make this work ?

Hi,

Yes currently, there the code is only compatible with Keras 0.3 and not the newer versions. I am hoping to fix this, but I am quite busy with other projects at the moment. I've relabelled this issue as an enhancement to make the code work with Keras > 0.3.

If you have insight on what is necessary, or even feel motivated to make the changes, I would happily support that though (e.g., via a pull request).
