Arch Linux

Package versions:

* community/mayavi 4.5.0-4
* community/vtk6 6.3.0-5
* community/vtk 7.1.1-1


Description:

I cannot get Mayavi to work at all, and it doesn't play well with vtk 7. First, if I run the following command from a python2 console:

from tvtk.api import tvtk

I get either a segfault (see attachment) if vtk 7 in installed, or the following message if vtk 7 is not installed:

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.7/site-packages/tvtk/api.py", line 11, in <module>
from tvtk.tvtk_access import tvtk
File "/usr/lib/python2.7/site-packages/tvtk/tvtk_access.py", line 43, in <module>
raise ImportError(msg)
ImportError: No module named vtk

Do you have vtk installed properly?
VTK (and build instructions) can be obtained from http://www.vtk.org


Not that in both cases, vtk6 is installed (as it is a dependency of mayavi).


Moreover, no matter whether vtk 7 is installed or not, I cannot start mayavi2, as I get the following error:

Traceback (most recent call last):

I also can't get 'import vtk' to work even without mayavi installed, but that probably warrants another bug report.
