[Paraview] pvbatch vs python shell (3.6.1): pvbatch crashes

[Weirs, V Gregory]

Hi Jonathan,
As you have probably gathered, there are two interfaces to the python scripting - servermanager, which was in 3.4, and simple, which is in 3.6. I haven't had any success with backwards compatibility, despite the "compatibility mode", and you are mixing and matching servermanager and simple. I don't know exactly why you get different results in pvbatch and the GUI, but I would try to replace the servermanager commands by the simple commands. (Note that servermanager is still in 3.6 and later, and sometimes you need it, but mostly you get to it through simple.) In particular:
1.) I don't think you need the connection line
2.) Remove the CreatRenderView line, an equivalent will be added in 4
3.) rep = Show(contour)  # replace the CreateRepresentation line
4.) view = Render() # replace the ResetCamera and StillRender lines
5.) WriteImage("./foo.png")  # replace the view.WriteImage line

Under the hood, some key changes are that paraview is using the active filter, representation, or view when you don't specify it; and is creating a representation or view if you don't have one but you need it. This is why you don't have to create a view or representation directly, Show() and Render() are creating them.

I am not sure if these changes will actually fix the errors you list, but that is where I would start.
Later, eh.

Hi:

I'm just starting to try to learn the python scripting interface to
ParaView 3.6.1, taking bits and pieces from various tutorial slides
scattered over the web.   I've managed to put together something that
works fine in the python shell on the client side, but when I try using
the same script with pvbatch it crashes.  What am I doing wrong?

I cut down the script; the following is what I've been trying to run
with pvbatch.

from paraview.simple import *

sm = servermanager

connection = sm.Connect()
view = sm.CreateRenderView()

reader =
XMLPartitionedRectilinearGridReader(FileName="draping.0030.bin.pvtr")
pointData = CellDatatoPointData(Input=reader)
contour = Contour(pointData)
contour.ContourBy='density'
contour.Isosurfaces=[100]
rep = sm.CreateRepresentation(contour,view)

view.ResetCamera()
view.StillRender()
view.WriteImage("./foo.png", "vtkPNGWriter")

When I run this (modulo the sm.Connect()) in the python shell on the
client (server launched with mpirun -np 80 pvserver
--use-offscreen-rendering) it produces what I'd expect.

But run with pvbatch, it dies pretty convincingly:

$  mpirun -np 80 pvbatch --use-offscreen-rendering ../foo.py
