[MayaVi-users] Problem loading data file

[david w. <dav...@gm...>]

I am using mayavi2 on Linux platform.

Even though creating parametric surface and builtin images seem to work,
loading a vtk or vtu file gives errors and nothing is displayed.
Here is a typical log after loading heart.vtk (the example file):

Any help appreciated.
