When I execute plot3d(lambda u,v:(u^2+v^2)/4-2,(-2,2),(-2,2))
The Edge browser(firefox deb also) shows a blank space, only an ‘i‘ in the lower right corner. The browser console reports an error.
three.min.js:1
Failed to load resource: net::ERR_FILE_NOT_FOUND

jmol works well
plot3d(lambda u,v:(u^2+v^2)/4-2,(-2,2),(-2,2)).show(viewer='jmol')
I use sagemath9.5 installed by 'sudo apt install sagemath' on ubuntu23.04
How can I solve it?
