Unable to pass a variable to Paraview script

I have the following bash script

for f in C:/folder/inside/my_stuff/*; do
    cd "$f" && 
    for file in *.ply; do
        "C:\\Program Files\\ParaView 4.4.0\\bin\\paraview.exe" --script="C:\\folder\\inside\\my_stuff\\screens2.py" $file
    done
done

The script is supposed to load .ply files into Paraview and then execute a number of commands, but I need to pass $file to the Python script so it would know which file to open.

The beginning of my script looks like this:

#### import the simple module from the paraview
from paraview.simple import *
import numpy as np
import glob
import sys
#### disable automatic camera reset on 'Show'
paraview.simple._DisableFirstRenderCameraReset()

files = sys.argv[1]

But when I run the script I get an error:

File "<string>", line 9, in <module>
AttributeError: 'module' object has no attribute 'argv'

So the variable is not passed to the script. Oddly, the .ply file does load into Paraview but none of the commands are executed. I tried sys.argv[0], sys.argv[2], sys.argv[3], sys.argv[file], sys.argv['file'], but nothing works.

ParaView does not forward arguments to script. Unknown command line arguments are interpreted as file to open in ParaView.

Depending on what you want to do, you should either:

  • use pvpython executable instead of paraview one (if you don't need to use the GUI by yourself)
"C:\\Program Files\\ParaView 4.4.0\\bin\\pvpython.exe" "C:\\folder\\inside\\my_stuff\\screens2.py" $file
  • put the for loop inside your script and reset session between each file
