Ethan Welty <ethan.we...@gmail.com> added the comment:
I've tried with additional backends: WX, WXAgg, WXCairo, Qt5Agg (in matplotlib
speak).
With these, I can at least import matplotlib.pyplot, but as soon as say
matplotlib.pyplot.plot is called and the backend is loaded, the code breaks
(error message for WXAgg below). Is multiprocessing in an interactive shell
simply not meant to be supported on MacOS?
Error in atexit._run_exitfuncs:
