when I run "python3 main.py -e dqn_epsilon" I can see the animation but I don't get the graphs. I get the following error :

I fixed the issue by downgrading matplotlib to version 1.4.3
Thanks!
We'll test this on a few more machines to confirm then release a version lock. Let's leave this issue open until a fix is merged.
Addressed in release v1.0.3
