Operating system: Win 10  
Slicer version: 4.13.0 (Latest)  
Expected behavior: Loading multivolume data  
Actual behavior:

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):

AttributeError: module ‘vtkmodules.all’ has no attribute ‘VTK\_MAJOR\_VERSION’
