Hello everyone,  
I created a basic trace which creates a sphere with a simple half-plane clip. The trace runs fine with the python shell within the GUI framework. However, when I try to run the file using PvPython as instructed in [https://www.paraview.org/Wiki/PvPython\_and\_PvBatch](https://www.paraview.org/Wiki/PvPython_and_PvBatch), an attribute error throws up:

Help in this regard would be appreciated.  
Thanks,
