[OpenFOAM.org] set up python path for python in paraview compiled with openfoam

seanread · October 18, 2015, 07:22

I'm trying to get paraview working in external python environments such as idle, from what I've read it's simply a matter of adding a couple of bits to the python path.

I'm using linux mint 17.2.

How do I locate the directories that need to be added to the python path?

I am using OpenFOAM 2.4

Quick answer: If you are using the "paraviewopenfoam410" Debian package, it does not have Python support built into it

Edit:

WAIT! I was wrong! This package already has it! The folder that needs to be added the PYTHON search path is this:

Code:

/opt/paraviewopenfoam410/lib/paraview-4.1/site-packages

hey Bruno,

Thanks for getting back to me,

I didn't use the debian package - it wouldn't install on linux mint - I compiled myself, python is working fine in pvpython. Where would be the equivalent directory as compiled according to the instructions at http://www.openfoam.org/download/git.php?

Quick answer: Mmm... that reminds me that we can use a more generic path that should give us the path in any installation of OpenFOAM with ParaView 4.1.0:

Code:

$ParaView_DIR/lib/paraview-4.1/site-packages

And when in doubt, double-check it with these commands:

Code:

echo $ParaView_DIR/lib/paraview-4.1/site-packages
ls -l $ParaView_DIR/lib/paraview-4.1/site-packages

If by any change it doesn't work as intended, the path in 64-bit installation for 2.4.x with the system's GCC is:

Code:

$HOME/OpenFOAM/ThirdParty-2.4.x/platforms/linux64Gcc/ParaView-4.1.0/lib/paraview-4.1/site-packages

thanks Bruno, That did the trick just fine!

wait, check that, so now I can import paraview no worries, but paraview.simple is still giving an error "No module named vtkCommonCorePython". I checked the site-packages/vtk directory, there is a binary file called vtkCommonCorePython.so, but no .py file. Does this mean that my lib is missing files?

Quick answer: Googled:

Code:

ImportError: No module named vtkCommonCorePython

Got this: http://stackoverflow.com/a/24412030
Therefore, the solution is this:

Code:

export PYTHONPATH=$ParaView_DIR/lib/paraview-4.1/site-packages:$ParaView_DIR/lib/paraview-4.1/site-packages/vtk

Thanks Bruno, that got it working, I saw this thread but didn't think to change to the site-packages in the paraview path
