Error when running RemoteView example with Paraview pv_server.py

Charliebrowne · December 21, 2020, 1:28pm

Hi there I tried to run the default RemoteView live example but it fails when launching the server script (using Paraview as a backend 2nd script on this example page) -
Running ParaView 5.9.0-RC1-MPI-Windows-Python3.8-msvc2017-64bit on Windows 10 32GB Ram & NVIDIA GeForce GTX 670.
any clue ? I couldnt find any reference to this error type anywhere
Thanks a lot
Charlie
Here is the error thrown on server side :

Does Visualizer fail the same way with your ParaView bundle?

jourdain · December 21, 2020, 6:17pm

It looks like the latest twisted logger has a different API. Since the error seems to come from that line

You should try with ParaView 5.8

Hi, same story with Visualizer, please below:

Try to edit the python code by passing disableLogging=True to the start_server call.

Charliebrowne · December 27, 2020, 5:57pm

Hi Sébastien,

yes the disableLogging=True workaround did the trick with PV 5.9.0 RC1 (at least no more errors in window at server launch) - Though I have not tested functionally yet, thanks for the tip! Charlie

We’re following up in an issue: https://gitlab.kitware.com/paraview/paraview/-/issues/20419
Looks like there are some additional problems, too.
