[Matplotlib-users] Importing pyplot crashes python

[Brendan B. <bre...@br...>]

Hi,

	I decided to upgrade to matoplotlib 0.99.1.  I'm on Windows XP.  I 
downloaded matplotlib-0.99.1.win32-py2.5.exe and ran it.  It seemed to 
install.  Now when I try "from matplotlib import pyplot", Python 
crashes with one of those "pythonw has encountered a problem and needs 
to close" messages.  I tried uninstalling matplotlib, and I also 
uninstalled SciPy and upgraded that to the latest version (0.7.1) and 
then reinstalled matplotlib.  Still crashes.  Importing numpy on its 
own works, as does importing matplotlib on its own.

	How can I fix this problem?

Thanks,

What does the command `python.exe -v -c "from matplotlib import pylab"`
say?

MPL 0.99.1 contains a bug (#2903460) that crashes the _path module on
slow Pentium CPUs (at least when using Python 2.6). A updated installer
is available at <http://www.lfd.uci.edu/~gohlke/pythonlibs/#matplotlib>.

It might help to add the path where python.exe is installed to the
Windows search path. E.g. try `SET PATH=C:\Python25;%PATH%` before
running your program.

	I forgot to mention that I'm using Python 2.5.2.  Has anyone else 
encountered this problem?
