As a heads up, there is now a pyplot and a pylab packages on pypi.
I have created an issue with the pypi folks
https://sourceforge.net/p/pypi/support-requests/512/
and with both projects
https://github.com/javipalanca/pylab/issues/1
https://github.com/sirrice/pyplot/issues/2
I found both of these via SO questions so I suspect that there is a coming wave of confused new users who did pip install pyplot or pip install pylab.
