Issue showing implicit_plot3d in Sage using anything other than tachyon

JupyterLab
1

I’m having an issue with Jupyter Lab where 3D graphs I try to render in Sage do not show up. The viewer backends I have tried to force are: threejs, canvas3d, jsmol, and java3d. My graphs are able to render when I force the viewer to be tachyon, but the graphs are not interactive. I think this is related to an issue with nodejs, though I’m not sure how to resolve it. Below is what is returned in the terminal when I attempt to run a Lab notebook.

Very relevant edit: I should mention that this works fine in a regular Jupyter notebook.

Here is a link the my question on the Sage forum.

That error is harmless and not relevant. It’s just saying you can’t do jupyter lab build as an informational message.

These errors indicate that something is trying to load classic notebook extensions, which would not work in JupyterLab. That may be the problem.
