Assistance with switching to Theano from TensorFlow backend

Hi,

I've just purchase the liveVideo. I was trying to move to theano and i'm getting an error. Before i show my error here how my json file looks like

{
    "floatx": "float32",
    "backend": "theano",
    "image_data_format": "channels_first",
    "epsilon": 1e-07
}

Then i change the backend to "theano" and image_data_format to "channels_last".

This is the error i'm getting.

/Users/brendamainye/anaconda/envs/py35/lib/python3.5/site-packages/h5py/__init__.py:36: FutureWarning: Conversion of the second argument of issubdtype from `float` to `np.floating` is deprecated. In future, it will be treated as `np.float64 == np.dtype(float).type`.

You can find the C code in this temporary file: /var/folders/rd/xmt7lsxs4j95cdrp1ddl62v00000gn/T/theano_compilation_error_j055tq63
