No I don’t get the error when I remove `Interact()`.

I’ll also add that when I do `from paraview.simple import *`, I get this error many times:  
`#osp: INITIALIZATION ERROR --> could not open module lib ospray_module_ispc: The specified module could not be found.`  
and I think the error also generates in other parts of the code. I couldn’t find a solution for it and the functions seemed to work fine so I ignored it for now.

I’m also using Anaconda Prompt and Spyder to edit my script. Perhaps my paths are not configured correctly? I’m not too sure.
