[Paraview] problems using pvbatch in frozen build

[Burlen Loring]

Hi All,

I'm encountering some issues when trying to use pvbatch from a frozen 
build(PARAVIEW_FREEZE_PYTHON=ON). Seems that certain key python modules 
are missing.ie math. However, I can use Python shell feature in the GUI 
from the same build. Do we have any idea about what may be wrong with 
pvbatch?


here is output from a simple test:

    nid00048:~$pvbatch pvbatch-test.py
    started
    Traceback (most recent call last):
       File "pvbatch-test.py", line 3, in <module>
         from paraview.simple import *
       File
    "/usr/common/graphics/ParaView/builds/PV-4.4.0/lib/site-packages/paraview/simple.py",
    line 40, in <module>
         import lookuptable
       File
    "/usr/common/graphics/ParaView/builds/PV-4.4.0/lib/site-packages/paraview/lookuptable.py",
    line 21, in <module>
         from math import sqrt
    ImportError: No module named math

I tried this as well:

    nid00048:~$pvpython
    Python 2.7.9 (default, Jan  8 2015, 22:29:31)
    [GCC 4.9.1 20140716 (Cray Inc.)] on linux2
    Traceback (most recent call last):
       File "/etc/pythonstart", line 7, in <module>
         import readline
    ImportError: Excluded frozen object named readline
     >>> import math
    Traceback (most recent call last):
       File "<stdin>", line 1, in <module>
    ImportError: No module named math
     >>>

Thanks
Burlen
