Hi,
I had a quick look and it's just import statements in pytrainer. matplotlib is
doing something during construction (building a font cache?), so I checked the
history on github:
https://github.com/matplotlib/matplotlib/commit/d5403fb6e5210b071810a6492114e51e9aa0d635
…where they're doing something with Python 3 or some unicode issue. My guess
would be the font metrics contain characters beyond ASCII (pretty much as the
error describes!). Can't find a bug/issue for it though.
Probably worth mentioning to them.
