As said in the comments, the problem lies in your script. Actually, there are 2 problems:

• There is a matplotlib error, I guess that you're passing an argument as None somewhere. Maybe due to the defaultdict ?
• You call show() after each subplot. show() should be called once at the end of your script. The alternative is to use interactive mode, look for ion in matplotlib's documentation.
