[Paraview] Paraview Python scripting

Tue Nov 1 10:13:01 EDT 2011

Sta.py is a Python state file I have created using "Save state" in the GUI.
Yes, it needs to open the GUI and load the whole pipeline saved in the
Python State file.

What does sta.py do that it needs to open the GUI? Do you mean an X11
window?

Hello Utkarsh,

The Python Shell works fine.

On the other hand, if you mean using  pvpython this way:

>> /home/david/ParaView-3.12.0-RC2-Linux-x86_64/bin/pvpython ./sta.py

It doesn't work... The GUI will   flash  (open partially and shutdown
quickly) and we cannot see anything...

Thanks again!

David

Have you tried using the pvpython executable? It's sets up the environment
correctly for you. Alternatively, from the GUI, you can open the Python
Shell and and then use the "Load Script" button to load the script.

Hello,

I'm manipulating different dataset and for each of them I have a different
setup (pipeline). I saved the state as a python file and plan to re-use the
python state file to re-open the whole pipeline for each dataset. It seems
that only *.psvm files can be loaded via   File -> Load state  in Paraview.
Is there a way to load a python state file?

Here is what I tried to do so, but didn't succeeded.

1- I followed the procedure for Paraview/Python scripting, and added
PYTHONPATH in .bashrc:

export
PYTHONPATH="/home/david/ParaView-3.12.0-RC2-Linux-x86_64/lib/paraview-3.12/site-packages/:/home/david/ParaView-3.12.0-RC2-Linux-x86_64/bin"

* The only thing I can't do is adding the path to
="/home/david/ParaView-3.12.0-RC2-Linux-x86_64/Utilities/VTKPythonWrapping/site-packages 
since I don't have any  Utilities  folder in my Paraview directory. I
believe this is required, but don't know what to install and where to get
it to have it...

2- I tried to load the python state file via python with the setup
described at step 1, but got the following error:

>> python ./sta.py

Traceback (most recent call last):

  File "/home/david/CADv2/Patients/P1/Prone/sta.py", line 2, in <module>

    except: from paraview.simple import *

  File

line 39, in <module>

    import servermanager

  File
"/home/david/ParaView-3.12.0-RC2-Linux-x86_64/lib/paraview-3.12/site-packages/paraview/servermanager.py",
line 43, in <module>

    import paraview, re, os, os.path, new, sys, vtk

  File
"/home/david/ParaView-3.12.0-RC2-Linux-x86_64/lib/paraview-3.12/site-packages/paraview/vtk/__init__.py",
line 1, in <module>

    from vtkCommonPython import *

ImportError: No module named vtkCommonPython

I have taken a look and there is no vtkCommonPython module on my machine.
Is it part of the VTKPythonWrapping in Utilities?

Thanks for helping me with this one.

David
