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

[Benjamin Root]

Yup, I think that is your problem. You will want to do a "sudo pip
uninstall pylab". By the way, it is really a bad idea to do any pip
installs with sudo. Pip installs execute arbitrary code, and you don't want
to give arbitrary code sudo access. Furthermore, it is probably best to
maintain a distinction between the "user's python" and the "system's
python". This is why virtual environments or anaconda has been so valuable
because it helps with maintaining that distinction.

I hope that helps!
