[Matplotlib-users] DLL not found when importing pylab on Windows

[Paul R. <pau...@nr...>]

Hi,

A colleague of mine uses Python on Windows.  When he upgraded to  
matplotlib 0.90 (from 0.82, I think) he started getting an import  
error when importing pylab.  We tried many combinations and the only  
thing that fixed it was downgrading back to 0.82.

We tried:
python2.4 and python2.5
numpy 1.0.1 and 1.0.2
matplotlib 0.90 and 0.87.7

We got the same error with all of those combinations.  The error  
message was an "ImportError: DLL load failed", when doing "from  
matplotlib._ns_transforms import *".  It is the same problem that  
others reported earlier:

msg02841.html
All of our installs were from the .exe Windows binaries, not source  
compilations, and in all cases import numpy, numpy.test(1), and  
import matplotlib produced no errors.
Note that we have not installed either Numeric or numarray, but we  
tried adding Numeric and it didn't help.

Has anyone found a solution?  We'd like to upgrade to a matplotlib  
later that 0.87.5 to get matplotlib.patches.Ellipse().

Thanks,
