[vtkusers] How to import vtk in python?

[David Thompson]

Hi Lin,

This problem is usually caused because VTK libraries and Python files are not installed in Python's default search paths. Try setting the PYTHONPATH environment variable to include VTK's lib and lib/site-packages directories.

Alternatively, instead of running Python, run the vtkpython program that gets built as part of VTK. It automatically adds the correct search paths and starts up a Python interpreter for you.
