[vtkusers] from vtk import * ImportError: (Python VTK 6.2 on ubuntu 14.04)

[Shawn Waldon]

Hi Manjunath,

Please keep discussions on the list so that others can benefit later.

I haven't used an install tree on Linux for a while but according to my
notes you should need the following assuming it is installed to /usr/local:

export
LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib/python2.7/site-packages/vtk:$LD_LIBRARY_PATH

export PYTHONPATH=/usr/local/lib/python2.7/site-packages:$PYTHONPATH

HTH,
Shawn
