python error: no module named pylab
You'll need to install numpy, scipy and matplotlib to get pylab. In ubuntu you can install them with this command:
sudo apt-get install python-numpy python-scipy python-matplotlibIf you installed python from source you will need to install these packages through pip. Note that you may have to install other dependencies to do this, as well as install numpy before the other two.
That said, I would recommend using the version of python in the repositories as I think it is up to date with the current version of python (2.7.3).
I installed python-numpy python-scipy python-matplotlib, but it didn't work for me and I got the same error. Pylab isn't recognized without matplotlib. So I used this:
from matplotlib import pylabfrom pylab import *and worked for me.
