ImportError: DLL load failed while importing vtkIONetCDF: The specified procedure could not be found.

Hi,

I am currently working through the VertexWiseR tutorial and have encountered persistent VTK-related errors that I have been unable to resolve. I am reaching out for assistance in troubleshooting this issue.

it seems the most recently released vtk 9.4.0 python package is causing the problem. We will fix this in the next CRAN release. In the meantime, you can simply install an older version of VTK with

reticulate::py_install("vtk==9.3.1",pip = T)

and then restart R/RStudio

I performed it correctly after installing VTK 9.3.1. The issue was resolved. Thank you very much!
