[Neuroimaging] Problem with from dipy.viz.fvtk

Mon Jun 13 07:39:17 EDT 2016

Hi Samuel,

thank you for the reply!
Finally there is solution for arch linux (also manjaro)!
So, in case someone has the same problem, he needs to install *vtk-qt4
7.0.0-2 *(here: https://aur.archlinux.org/packages/vtk-qt4/)
and it works!

Cheers,
Vassia
