shash29-dev commented 2 years ago

while using any function of mlab module e.g. quiver3d, points3d, a trait error is thrown.

traits.trait_errors.TraitError: The 'stereo_type' trait of a XOpenGLRenderWindow instance must be 'red_blue' or 'anaglyph' or 'checkerboard' or 'crystal_eyes' or 'dresden' or 'emulate' or 'fake' or 'interlaced' or 'left' or 'right' or 'split_viewport_horizontal' (or any unique prefix) or 1 or 10 or 11 or 2 or 3 or 4 or 5 or 6 or 7 or 8 or 9, but a value of 'red_blue' <class 'str'> was specified.

I also have this issue, if you find a solution please let me know!

This results from an incompatibility between the recently released Traits 6.3.0 and the most recent release of Mayavi. Either upgrade to Traits 6.3.1, or use Traits 6.2.0 for now.

I'll close here; this should be fixed at this point. @shash29-dev Thanks for the report; please do comment if you find that the issue persists with Traits 6.3.1. Confirmation that Traits 6.3.1 fixes the issue for you would also be appreciated, if that's the case.

Thanks for the response. Downgrading to traits 6.2.0 works!!

Also, I would like to point out the following: With vtk version: 9.0.3, which is automatically installed by pip as a dependency of mayavi, the import from mayavi import mlab stucks. I built vtk version 9.0.0 from the source and now mayavi is working fine.

Thanks; this is a known issue, tracked in #1073.
