Hi, I am new in this community. I try to read a vtp file, it is a DTC hull which can be read by Paraview.
I write a python script to read this file 🙂
```auto
import vtk
filename = "hull.vtp"
reader = vtk.vtkXMLPolyDataReader()
reader.SetFileName(filename)
reader.Update()
polydata = reader.GetOutput()
```
but I have an error :
```auto
ERROR: In vtkXMLReader.cxx, line 341
vtkXMLPolyDataReader (000001949E6459B0): Error opening file hull.vtp
ERROR: In vtkExecutive.cxx, line 730

Maybe someone can help me please ! Thanks a lot

In any case, it is probably too big to share here, you can use [wetransfer.com](http://wetransfer.com) instead 🙂

It works well here. How did you install VTK ?

Understood, more investigation needed to understand why this is happening on your side.
