I couldn't get it to run until I commented out L21 and L22. Then I get:

blink(1) found
fading to #ffffff
Traceback (most recent call last):

I understand the python lib is supported by someone else, but if you look at their fork, you can't even create a issue there.

It seems like you should probably pull python from marketing materials until someone gets the time to clean up all the python issues. :\

Are you on Python2 or Python3? The library in PyPi is only for Python3 I believe.

But I agree. I'm working with Salim to get the PyPi library transferred over. For now with Python2 you may have more luck with one of these libraries: https://github.com/todbot/blink1/tree/master/python/alternative_libraries

Version 2, which is the default for OSX and Ubuntu 14.04LTS at the very least. Having it only work with 3 and not be backwards compatible seems like a dis service?
