  Theano deprecation warning
  I have started running my code with warnings as errors.  Theano trips the deprecation warning:
  
  ```
    File "/opt/local/Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5/configparser.py", line 1209, in __init__
      DeprecationWarning, stacklevel=2
  DeprecationWarning: The SafeConfigParser class has been renamed to ConfigParser in Python 3.2. This alias will be removed in future versions. Use ConfigParser directly instead.
