Python version specific matplotlibrc #10376
Description
Bug report
Bug summary
There should be a way to use different config files for different python versions, or at least specify different backends for different versions. I have PyQt5 installed for python3, so I prefer to set my backend to Qt5Agg. But occasionally I want to run something in python2 for testing or compatibility purposes. I don't want to waste time and space installing PyQt5 on python2, so I want the backend to stay TkAgg. A workaround is to change the config files in the matplotlib installation, but these will be overwritten on the next install.

You could use the
MPLBACKENDenvironment variable to do that, e.g., if you're using bash, thenalias pympl2='MPLBACKEND=TkAgg python2'could work.rmccampbell commentedon Feb 4, 2018
I'm on windows (I could accomplish the same with a bash script) but I would much rather avoid using aliases if possible. By the time I remember I forgot to use the alias I might as well just call mpl.use('TkAgg').

This would fit with in @anntzer 's advocacy to have the configuration just be a python script.
With our current system this would be a pretty big jump in complexity.

The original use-case has become obsolete due to dropping of Python 2 support. Please reopen if this is still a desirable feature.
