I just installed MaxFEM on Windows 10. I follow the tutorial and when I try any option in Visualization, I get this error message in the black screen: "ImportError: No module named vtk". I then installed VTK-8.0.0, and it did not change anything. I cannot see any of the following windows: 4. Visualization bar 5. Visualization menu 6. Scale 7. Visualization window 8. Scale bar 9. Time bar What should I do? Thanks
