Hi developers,
I am trying to load my t2 images map with different TEs and python interactor gives this message:

Loading with imageIOName: GDCM
Window/level found in DICOM tags (center=3602.0, width=7204.0) has been applied to volume 8: SAG T2MAP
Failed to read a multivolume: module ‘vtkmodules.all’ has no attribute ‘VTK_MAJOR_VERSION’
Traceback (most recent call last):

if vtk.VTK_MAJOR_VERSION <= 5:
