[Paraview] Importing paraview.simple with Python 3

[Cory Quammen]

Nick,

One can indeed compile ParaView with Python 3. However, the binaries
available on paraview.org are built with Python 2.7. If you wish to
use Python 3, you will need to compile ParaView yourself against
Python 3.

How exactly are you attempting to use the ParaView binary in a Python
3.6 environment?

Best,
Cory
