[Paraview] python scripting

Mon Mar 18 04:09:06 EDT 2013

Please copy the paraview at paraview.org mailing list when you reply.

Are you using python2.5 to run you script?  Does your version of OSX have
python2.6 or python2.7 (in /usr/bin) ?  On my machine, the system version
of numpy for pthon2.5 is only available in i386, while later versions
contains i383 and x86_64 architectures.  ParaView will require the x86_64
arch.  Can you use python2.6 to run the script?  Otherwise, you'll have to
install a newer python and numpy.
