I am unable to import pylab
using the latest version of Anaconda (Linux 64 bit). Other packages seem to work fine. (Note: I don't have sudo
access)

Any thoughts on why?
Just had this problem and it was related to which qt backend matplotlib was trying to use, try:
If you don't have PyQt4 you probably have PySide
If this is the case you need to set the
matplotlib.rcParams['backend.qt4'] == 'PySide'
not'PyQt4'
. You can also do this in your matplotlibrc file (~/.matplotlib/matplotlibrc)Note: if you don't have the matplotlibrc file you can copy it from the matplotlib source directory
