[Paraview] ParaviewWeb Examples | Python Libraries | Import Error

[Sebastien Jourdain]

Hi Leo,

the documentation has been updated to match paraview/master from maybe 2
weeks ago.
If you have an older version of ParaView, you would have to look at an
older version of the ParaViewWeb documentation of that example.
Or update your ParaView to the current master.
