doesn't work out of the box

Hello,

I tried to launch this project locally. I set my keras to use theano, python = 2.7; its ubuntu.

Traceback (most recent call last):

This seems like a potential problem with keras / theano.
Please upgrade both versions and try again.

Also please check the versions of both by:
import tensorflow as tf
print tf.__version__
import keras
print keras.__version__

Actual problem was mismatch between backend and image_dim_ordering; I changed the backend to theano but forgot the image ordering.

A correction to ~/.keras/keras.json solved it:

{
"image_dim_ordering": "th",
"epsilon": 1e-07,
"floatx": "float32",
"backend": "theano"
}
