I think you would be better off running your script with

./pvpython <name of script>

pvpython comes with the ParaView binary and is located in the same
directory as the 'paraview' executable. pvpython uses the same Python
as ParaView is, so compatibility with some local Python on your system
is not a problem. Further, pvpython sets up Python environment to
provide access to the ParaView and VTK Python modules without having
to set up any environment variables.

python3 definitely won't work with the official ParaView binaries,
which are built against Python 2.7.
