[Paraview] pvpython and matplotlib

[Adriano Gagliardi]

Hi Aurelian,
 
I'm using a 64-bit build of ParaView 3.10.1 on Centos 5.4. 
 
How did you go about debugging this last time?
 
Thanks,
 
Adriano

Good morning Adriano, 
 
All is working fine for me. 
But I remember that pyplot.show() didn't work from the paraview python sheel
with previous release. 

It looks like you have the 2.4 verions of Python. Which Paraview version do
you use ? 
 
Regards,

Dear All,

I am having issues getting matplotlib to work with a in-house compiled
version of pvpython. Although it imports fine, if I try to plot anything
using pyplot I exit with a segmentation fault. Likewise, when I exit
pvpython, I get a segmentation fault. However, when using matplotlib from
the standard release of Python, it all works fine. Other libraries like
mysql and numpy are working fine too. This is what I'm running:

import matplotlib.pyplot as mp
#import pdb; pdb.set_trace()
mp.plot([1,2,3])
mp.show()

Any suggestions what could be wrong or how to go about solving it? I've
noticed the -v/-vv flags don't work with pvpython, or -h for that matter.
I'm at least finding the point at which I get the segmentation fault, but I
can't make head nor tail of it:

(Pdb) s
> /usr/lib64/python2.4/site-packages/matplotlib/transforms.py(286)zero()
-> def zero(): return Value(0)
(Pdb) s
--Return--
>
/usr/lib64/python2.4/site-packages/matplotlib/transforms.py(286)zero()-><Bin
Op o...1ce469a8> <--- it gives a segmentation fault before this line
-> def zero(): return Value(0)

All suggestions greatly appreciated.

Thanks,

Adriano
