[Paraview] [EXT] Re: Using Pandas in Paraview v5.4.1

[Scott Wittenburg]

Hi Dennis,

I'm not sure I understand precisely what you mean when you say "compile
here with an external python".  Do you mean compiling your plugin (which
would imply not a simple xml plugin), or compiling ParaView?  Even if you
compile ParaView on your end with an external python, I don't see how that
will result in something that will allow you to distribute your plugin as
xml.  You could try to distribute a custom ParaView binary (which includes
your new plugin as well as pandas python modules), but for that you would
normally need to use the ParaView superbuild.  Even then I think you would
have to tweak the superbuild to get the python to include pandas.

Hopefully someone out  there with more knowledge can chime in and provide
some hints or suggestions.  Then maybe we'll find out what you want to do
it quite easy, in which case I'll be excited to learn about it :-)

Cheers,
Scott

p.s.  I'm sure you may have read through this before, but just in case (or
for people who come across this later):
