Can't train network, basveeling's branch of Keras didn't help

I wanted to train the network on my own .wav files. I downloaded all the .py files, put the .wav files in the data/test and data/train directories, and ran wavenet.py without any arguments (as is shown in the readme). However, it apparently tried to predict using a nonexistent model:

WARNING (theano.configdefaults): g++ not detected ! Theano will be unable to exe
cute optimized C-implementations (for both CPU and GPU) and will default to Pyth
on implementations. Performance will be severely degraded. To remove this warnin
g, set Theano flags cxx to an empty string.
Using Theano backend.

(the last line says it can't find the path) After a bit of trial and error, I decided to install basveeling's branch of Keras (I installed the official one previously). However, that only worsened the situation:
