using latest keras and theano, I am getting a different error

Actually, the issue was related to Keras and not about your code. Latest version of Keras is now using tensorflow by default--I just had to modify the keras,json file to use theano backend and theano dimension ordering as follows: { "floatx": "float32", "image_dim_ordering": "th", "backend": "theano", "epsilon": 1e-07 }
Thanks for letting us know. At the very least, we will mention this in the README. Ideally we should modify the code to work with either Tensorflow and Theano as soon as we have time.
I upgraded to latest keras (1.1.0), and looks fine for both backend: Theano and TensoFflow. The only problem is related to the dimension settings, so "image_dim_ordering" must be set to "th", as you pointed out. Thank you!
Hi,
Thanks for making this code available. I wanted to give this a quick look. I am on Mac OS, installed latest Keras and Tensorflow. Tried on python 3.5 after 2to3 for mostly the print statements.
Here is the error I am getting:
