Hi A,

Sorry to disappoint but this package is only compatible with Python 3.4+. Looks like you are running Python 2.7.6.

I am able to reproduce your error when I try to use this package in a Python 2.7.6 environment. I get no errors when I use this package in a Python 3.4+ environment.

Hope this helps.
