Good morning,

I am trying to integrate some arrays within a .VTK, and found about the “vtkIntegrateAttributes”, but on python that module seems to not exist. I am using vtk8.1 with python2.7. What could be the problem?

“”  
import vtk  
vtk.vtkIntegrateAttributes()

‘module’ object has no attribute ‘vtkIntegrateAttributes’

“”

Kind regards.

The `vtkIntegrateAttributes` was added to VTK in 8.2.0, so 8.1 won’t have it.
