There are two main ways to install VTK - 1) as part of Paraview or 2) stand alone. In the following instructions, I've built Paraview and VTK has been installed as part of that process. I have built paraview in '/home/doriad/bin/ParaView3'

To run a vtk python script, simply type: python script.py

If you receive this error: ImportError: No module named vtk

add the following line to ~/.bashrc export PYTHONPATH=$PYTHONPATH:/home/doriad/bin/ParaView3/VTK/Wrapping/Python/

Try to run the script again. If you get something like this: ImportError: libvtkCommonPythonD.so.pv3.7: cannot open shared object file: No such file or directory

Add the following to ~/.bashrc export LD_LIBRARY_PATH=/usr/local/lib:/home/doriad/bin/ParaView3/bin
