implicit_plot3d not rendering in Jupyter Lab [closed]

edit

I'm unable to see any 3D plots in Jupyter Lab. I have tried forcing viewer="threejs"in the argument of a similar object, and have the same issue. Here's a screenshot of what it looks like: https://imgur.com/a/K8R3pZr. Any suggestions?

Edit: I'm running Ubuntu 20.10.

Update: I'm able to plot in Jupyter Notebook, so it's probably an issue with Jupyter Lab.

Update: forcing viewer = "java3d",viewer = "canvas3d", viewer = "jsmol" doesn't work either.

Update: I ran sage -n jupyterlab in the terminal. Everything seems to work fine until this:

Update: Forcing viewer = "tachyon" works, but is not interactive.

Update: There must have been something wrong with how I installed Sage. I reinstalled using Anaconda and it works fine now.
