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

[Dennis Conklin]

Scott,

I assume that if I compile a ParaView executable with pandas included, then I 
could distribute my plugin as xml and everyone could access it.I’m a little 
unsure but I assume I would also have to recompile the server that we are using 
on an HPC cluster to include pandas.   I’m beginning to see why adding pandas 
to ParaView has been delayed a few times.

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

Scott,

Interesting idea and I was not aware of any of that.

I should be specific that I need to make an xml Server side plugin for general 
distribution that needs to call pandas to execute.   So I don’t think I can get 
everyone here to load up that virtual environment and install pandas.

I think I’m hearing that pandas for everyone is not available unless I compile 
here with an external python, right?

Thanks

Hello Dennis,

Depending on how you want to use pandas within ParaView, one approach that 
could work involves creating a virtual environment and installing pandas there. 
 Then a couple of lines of python can make modules installed in that virtualenv 
available from pvpython.  See this blog post for more information:

Hope this helps,
Scott
