Really annoying matplotlib errors when you import peartree
This has to do with the .use('Agg') setting. This should be updated to only be used when not in a repl like a notebook / used in the cl.

This call to matplotlib.use() has no effect because the backend has already
been chosen; matplotlib.use() must be called *before* pylab, matplotlib.pyplot,
