Please help for plot3D on colab

[AlbLRC]

There is always error when using "sim.plot3D()" on Colab.
I have install the "vispy" and "PyQt6" according to "Gemini's" suggestion, but still won't work.
Could any one please help?
Thanks a lot!

Hi AlbLRC, since Meep's plot3D() relies on vispy, I suggest first making sure it works:
https://vispy.org/
If you need further troubleshooting, it would help to post more details about the error and what code causes it.

Hope this helps!
