Actually, the best way to solve this would be to get rid of Jupyter as a
part of Sage the distribution.
Then one can install these kernels in a normal Jupyter way - without it
being a kind of
afterthought 2nd class citizen way.
No project I know, apart from Sage, vendors Jupyter. Vendoring Jupyter is
just a needless bloat.

[sage-support] Re: Is there a way to use Sage's Jupyter outside the sage shell ?

[Nils Bruin]

If you run `jupyter --paths` and  `sage -sh <<<"jupyter --paths"` you see 
the difference in paths. The relevant ones for you are probably the 
sage-specific ones
$SAGE-LOCAL/var/lib/sage/venv-python3.10/share/jupyter
Whatever is there will get picked up by sage's jupyter but, naturally, not 
by your standard jupyter.
So the kernels that live there could be copied to a location that is 
accessed by your system jupyter:
$HOME/.local/share/jupyter
or something like that.

Note that the files there might need some surgery, because starting those 
kernels probably needs to happen through sage's python (or at least its 
venv); similar to how to get the sage kernel working in a system jupyter.

[sage-support] Is there a way to use Sage's Jupyter outside the sage shell ?

[Emmanuel Charpentier]

Setup : Sage 10.4.beta1 running on Ubuntu 22.04 LTS under WSL2 in Windows 
11 (don’t get me started…). I also installed emacs and its juyter 
 package, which is able to use 
Sage-installed kernels … when emacs is started from the Sage shell. [ Yes, 
there is a point to this…]

What I want to do is to be able to use these Sage-installed kernels from 
outside the Sage shell environment, thus avoiding to duplicate the Sage 
Jupyter installation. In other words, I want a jupyter command that is able 
to finfd the Sage-instaled kernels in their correct environment.

Is there any way to do that ?
