Windows - Unable to import Pylab. Pb with Polar

Sorry i have ever post this message in the support section of Maybe it was bad.
I try another time here :slight_smile:

I have Python 2.3
Pygtk 2.4.1
gtk runtime environnement 2.6.2 rc1
I tryied with every version of Matplotlib since 0.63. Same error is happening: ImportError: cannot import name POLAR.

I decided to edit files:
- C:\Python23\Lib\site-packages\matplotlib\
l.36 put , NonSeparableTransformation in comment
l.37 put ,Polar in comment

- C:\Python23\Lib\site-packages\matplotlib\
l.189 put ,Polar in comment
l.190 put , NonSeparableTransformation in comment

After that, it works well.
But i have no idea why this problem happened.
A colleague of mine hadn't to do it and it works perfectly.

Does someone have any idea?
