[Matplotlib-users] TkAgg won't plot - how to debug?

Wed Nov 8 17:43:07 EST 2017 

i'll take a look @ conda. Thank you.

Meanwhile. i resolved the problem with "missing" plot, backend packages
from matplot in pycharm - the /usr/lib64/python3.5 was absent from the
pycharm's config.
now i don't have any warnings from from pycharm - "what a charm!" (sorry,
couldn't resists) . But the example still won't work.

// another Tito's shot maybe due...
