Compatibility with Notebook 7

[casparvl]

I was trying to install jupyter-matlab-proxy, and saw that it lists a dependency on jupyter-contrib-nbextensions. It turns out that jupyter-contrib-nbextensions is incompatible with Notebook 7 (see here). Furthermore, jupyter-contrib-nbextensions hasn't been updated in 8 months.

I was wondering: does jupyter-matlab-proxy really need jupyter-contrib-nbextensions? I couldn't find any reference to e.g. imports, but I guess it could be used in different ways. In any case, considering the limited maintenance that seems to be happening on jupyter-contrib-nbextensions, it might be good to consider if jupyter-matlab-proxy could somehow be altered to avoid needing that dependency.

Hi @casparvl
Thank you for reporting this issue.

You are right, jupyter-matlab-proxy does not technically depend on jupyter-contrib-nbextensions.

Installing this package seemed to fix issues that some users were facing where the icons related to our integration would not be displayed on their JupyterLab interface.

So we decided to place a dependency on this package to reduce the incidence of this issue.

Given this failure with Notebook 7, I'm convinced that this package has outlived its intended purpose, and will remove it from the dependency list shortly.

Thanks @prabhakk-mw for that response. Until there is a new release: I guess I can just remove this line before installing, and that should be sufficient, right? Or do you know of more places where changes would be needed?

[prabhakk-mw]

That's probably all you need to change.
Let us know if that didn't resolve it, or if there are new issues that come up after you've installed for use with Notebook 7.

I haven't explicitly tested against Notebook 7 yet.

Thanks @casparvl

Ok, thanks again! It might be a while before I get back on this (I have a few other priorities right now), but if I do, I'll definitely let you know here.

Hm, I actually found a minute to try this out, but got a ton of errors:

  note: This error originates from a subprocess, and is likely not a problem with pip.
error: metadata-generation-failed

 Encountered error while generating package metadata.

Then, I checked your pyproject.toml again and saw jupyterhub<4.0.0 ... I'm guessing that is my problem here, I have 4.0.5, right?

I have a different software environment with a JupyterHub 3.X where I could give it a try, but I'll need to look into what dependencies I have available there, so it's a bit more work.

Hi @casparvl

We haven't been able to reproduce the issue at our end. Can you confirm if you are still able to reproduce the issue in a fresh environment and with latest versions of packages?

Here is what I've tried:

1. Created a new python environment using conda create -n jmp-gh-58 python=3.11.
2. Installed Jupyter Notebook and jupyter-matlab-proxy using python -m pip install --no-cache notebook jupyter-matlab-proxy. (using --no-cache flag to force python to download latest packages)
3. Installation of both packages work fine and I was able to launch Jupyter Notebook 7 and use MATLAB from Jupyter.

[prabhakk-mw]

@casparvl , We are closing this issue until we hear from you with responses to @rashedmyt 's questions.
Thank you for using the MATLAB Integration for Jupyter!

[casparvl]

@prabhakk-mw yeah, sorry for not being able to follow up on this. I was looking into this in September, when we got a request from a teacher to facilitate a MATLAB based course in our Jupyter environment. Since then, my priorities have shifted to other things. Sorry I wasn't able to test your suggestion, but in all honesty, it is unlikely that I can do so in the foreseable future. So closing the ticket is fine by me.

If, in the future, I do find the time, I'll report back. Thanks for the help in any case!
