[Matplotlib-users] Import error: Cannot import pylab modules

[Benjamin Root]

Can you do the following (from the python interpreter)

import pylab
print pylab.__file__

There has been a rogue package on pypi called "pylab" that we have been
trying to get taken off of the listing, since it conflicts with our
long-standing package and trademark. Nothing nefarious, just some person's
collection of dependencies that he decided to call pylab and uploaded to
pypi for his personal use.
