An environment variable PYTISSUE_NO3DDISPLAY can be defined to bypass any Mayavi 3D display. This appears necessary due to the difficulty to install Mayavi on all platforms: sometimes, traitsui fails, sometimes vtk fails, etc... By defining it in your environment, you can avoid bugs and run the code reagardless.

I think your installation issues were related to mayavi being pinned to 4.8.1, which is not compatible with the latest vtk (default on fresh installs). Considering the new mayavi release, removing the pin on |

This appears necessary due to the difficulty to install Mayavi on all platforms: sometimes, traitsui fails (8.0.0 has broken things apparently, and forcing old version not always possible), sometimes vtk fails (must be installed via mayavi, which does not always recognize it), etc... By defining in your environment:
you can avoid any buggy Mayavi install and run the code regardless, but without 3D visualization which is not required for the code to run.
