Bug#823529: paraview-python: Cannot import vtk inside pvpython

[Ganesh Vijayakumar]

Package: paraview-python
Version: 5.0.1+dfsg1-4
Severity: important

Dear Maintainer,

   * What led up to the situation?

I'm unable to import the vtk module inside pvpython. I would like to be able to use the vtk.numpy_interface.dataset_adapter module/package. Strangely, this works when using just python instead of pvpython.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
