[Paraview] pvpython and matplotlib

Wed Dec 14 11:28:48 EST 2011

Paul, 

I did so and it continued to work fine. I'm wondering whether it is related
to the TCL_LIBRARY variable not being set. Off to recompile it to find out.

Thanks,

Adriano

Does the system python also crash if you set the library path to have the
paraview directories?  If this is the case you probably gave a conflicting
lib in paraview.

System version is identical. The environment variables are identical with
the exception of those relating to window ids. LD_LIBRARY_PATH has changed,
but when running ParaView two directories, the paths to the ParaView root
and lib directories, have been added to the start. Nothing else is
different.

Aurelian, TCL_LIBRARY path is set, but I didn't configure this option when
compiling ParaView itself. I have numpy in the correct directory location.

Thanks,

Adriano

Try comparing environment variables (import os and compare os.environ) 

In order to check the version print sys.version (after import sys)

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, 

Aurelien

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
