Thanks for posting this. Looks like this is a `vtk` and `tensorflow` issue. I see that there's a similar issue posted on VTK's GitLab: [vtk #19777](https://gitlab.kitware.com/vtk/vtk/-/issues?show=eyJpaWQiOiIxOTc3NyIsImZ1bGxfcGF0aCI6InZ0ay92dGsiLCJpZCI6NTMxMzA3fQ%3D%3D ), I'm guessing that's...

If we can figure out how to make labels, we can also use ``matplotlib`` to display equations. I'm leaning towards approach A, but it's going to require more work.

Looks like `vtk==9.5.0` will have VTK wheels according to https://discourse.vtk.org/t/vtk-9-5-0-release/15018/2 Also, you may want to disable 32-bit Linux wheels. Looks like we're attempting to build for `i686` architecture.

> @akaszynski can you merge it? Not quite yet. Looks like ARM builds are still failing.

I'm seeing this bug in linux, but with `vtk==9.0.1`. Could you try upgrading `vtk` and see if the issue persists?

Sorry. Helps if I read these issues completely. Does this occur on vanilla python and just on iPython? I'm trying to think if it's due to our last release where...
