problem with import pylab

Hello:

I am having problem with “import pylab”. I attached the traceback below. I have googled on the web but haven’t found a solution. Can someone here help?

I have ActivePython 2.5, numpy-1.4.0-win32, and matplotlib-0.99.1.win32-py2.5.exe, and Windows XP SP3.

Traceback (most recent call last):
File “”, line 1, in
File “C:\Python25\lib\site-packages\pylab.py”, line 1, in
from matplotlib.pylab import *

Thanks.

Just based on the traceback, the problem seems to be in Tk - does anything in tk work for you? (e.g. any of the builtin python gui stuff) You might try installing wx and changing your matplotlibrc file to have the line “backend:WxAgg” in it. I’ve never tried using the wx backend on windows (anyone done this?), but presumably it should work…
