I am still having the same problem with PyPlot. I couldn't get it to work
in .3.10 for more than one session, before it broke.
LoadError: LoadError: InitError: Failed to pyimport("matplotlib"): PyPlot will
not work until you have a functioning matplotlib module. PyError
(:PyImport_ImportModule) <type 'exceptions.ImportError'>
ImportError('cannot import name scimath',)
