I have two nearly identical machine running Ubuntu 17.10. The both have the latest stable Paraview 5.4.1 from the download page installed in /opt.
I wrote a wrapper script like this: -------------------------------------------------------------------------------------------------------------------- #!/bin/bash # PVHOME=/opt/ParaView-5.4.1-822-g597adef-Qt5-MPI-Linux-64bit PVHOME=/opt/ParaView-5.4.1-Qt5-OpenGL2-MPI-Linux-64bit export PATH=$PVHOME/bin export LD_LIBRARY_PATH=$PVHOME/lib/ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$PVHOME/lib/paraview-5.4/ export PYTHONPATH=$PVHOME/lib/python2.7/bin/ export PYTHONPATH=$PYTHONPATH:$PVHOME/lib/python2.7/site-packages/ export PYTHONPATH=$PYTHONPATH:$PVHOME/lib/python2.7/site-packages/vtk/ export PYTHONPATH=$PYTHONPATH:$PVHOME/lib/python2.7/site-packages/paraview/ $PVHOME/bin/paraview -------------------------------------------------------------------------------------------------------------------- On each machine I start paraview and load a state that has a programmable filter with the line: d0 = inputs[0].PointSet['d'] One one machine, this works just fine. On the other machine, I get the following message in the Output: -------------------------------------------------------------------------------------------------------------------- Traceback (most recent call last): File "", line 24, in File "", line 2, in RequestData TypeError: 'NoneType' object has no attribute '__getitem__' BTW, this is just a test; obviously, my real filter does something. I assume that some module is not being loaded here, but I've tried _everything_ I could think of and I'm not making progress. Any ideas?? -- Martin Weinberg 6 Grass Hill Rd West Whately, MA 010039
