Hi,

This sounds like something I could use to run Jupyter notebooks inside an Android app for testing and benchmarking. But I had trouble getting it to work:

  1. pip install https://github.com/davidbrochart/jupyter_server/archive/kernels_extension.zip this does not work. It seems to try to install a jupyter_server that's a few year old? Could this work with upstream jupyter_server?
  2. It seems the dependency list is missing pip install jupyter_server_kernels
  3. From the README I am not sure which part is the "remote part" which only runs the kernels. My guess would be that the fps_uvicorn part runs the kernels but the comment on the bottom ("Kernels should now be served from http://127.0.0.1:8000/.") seems to suggest otherwise?

Thanks for all your work modularizing and updating the Jupyter core stack.

Hi @jpc,

  1. pip install https://github.com/davidbrochart/jupyter_server/archive/kernels_extension.zip this does not work. It seems to try to install a jupyter_server that's a few year old? Could this work with upstream jupyter_server?

I just pushed a commit that should fix it.

2. It seems the dependency list is missing pip install jupyter_server_kernels

Actually it is jupyter-server that will require jupyter-server-kernels, see https://github.com/jupyter-server/jupyter_server/pull/1106#issue-1468297606.

3. From the README I am not sure which part is the "remote part" which only runs the kernels. My guess would be that the fps_uvicorn part runs the kernels but the comment on the bottom ("Kernels should now be served from http://127.0.0.1:8000/.") seems to suggest otherwise?

No, you are right, fps_uvicorn runs the kernels, and it's running at http://127.0.0.1:8000. JupyterLab is running at http://127.0.0.1:8888. Both are actually running locally, and we are imagining that fps_uvicorn runs on another machine.

  1. Thanks. I initially missed that it's referencing the kernels_extension branch.
  2. :+1: works now.
  3. I've drafted a quick pull request that hopefully would make it a bit clearer in the README.

I got it to start on Chaquopy (Python distro for Android but I am getting 404s everywhere.

Unfortunately I don't have enough time to debug this properly right now.
