<p>Do you still get an error if you remove the call to Connect() near the top of the script?</p>

Hi,<br>
<br>
I'm wondering if the behaviour below is a bug. I have a pvbatch test<br>
script that runs fine under PV 3.10.1 and is actually based on an older<br>
PV tutorial:<br>
<br>
paulmlocal@sara11006:~/examples/paraview$ cat pvbatch_sphere.py<br>
# spherepic.py<br>
from paraview.simple import *<br>
<br>
sm = servermanager<br>
sm.Connect()<br>
<br>
sphere = Sphere()<br>
sphere.ThetaResolution = 100<br>
sphere.PhiResolution = 100<br>
<br>
pidscal = ProcessIdScalars(sphere)<br>
<br>
view = sm.CreateRenderView()<br>
rep = Show(pidscal, view)<br>
<br>
nbprocs = sm.ActiveConnection.GetNumberOfDataPartitions()<br>
lt = MakeBlueToRedLT(0, nbprocs-1)<br>
lt.NumberOfTableValues = nbprocs<br>
<br>
rep.LookupTable = lt<br>
rep.ColorAttributeType = 'POINT_DATA'<br>
rep.ColorArrayName = "ProcessId"<br>
<br>
bar = CreateScalarBar(LookupTable=lt, Title='PID')<br>
<br>
view.Representations.append(bar)<br>
view.ResetCamera()<br>
view.StillRender()<br>
view.WriteImage("Sphere.0.png","vtkPNGWriter", 0)<br>
<br>
<br>
When running this with the binary distro of 3.12.0 on a Linux x86_64<br>
system I get:<br>
<br>

Looking at the stack trace this seems to be something in the<br>
