[vtkusers] Errors in "vtkpython" interpretor (vtkpython 6.3.0.rc1 and pyQt5.2.1 )

[Shawn Waldon]

Hi Manjunath,

I think it may be easier to just get your system python to import vtk.  The
paths in the vtkpython executable are compiled in and cannot be
overridden.  I think you just need to add $vtk_install/lib and
$vtk_install/lib/python2.7/site-packages to your PYTHONPATH environment
variable to import vtk from the system's python.

HTH,
Shawn
