Jupyter notebook extension on remote server does not work after VScode downgrade.

[amirhosseindavoody]

Environment data

• VS Code version: 1.85.2
• Jupyter Extension version (available under the Extensions sidebar): v2023.11.1100101639
• Python Extension version (available under the Extensions sidebar): v2023.20.0
• OS (Windows | Mac | Linux distro) and version: Windows 11, using remote devepment on Suse 12
• Python and/or Anaconda version: python 3.9
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): using pixi package manager
• Jupyter server running: This is a remote development environment but the jupyter server is running locally on the remote machine.

Expected behaviour

The jupyter notebook should autocomplete the variable names and show list of live variables.

Actual behaviour

None of the functionalities of jupyter notebook extensions for autocomplete and showing existing variables work.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

I don't have exact instructions, but this happened when I had to revert back from vscode 1.86 release to 1.85.2 because of glibc version incompatibility on my remote machine. Then I found out that the extensions have been upgraded too. So, I reverted back the extensions to some previous version from back in November. The extensions I reverted are Jupyter notebook, pylance, and vscode-python. Now, none of the functionalities for jupyter notebook work. Python extension seems to work for now. I get autocomplete in .py files but nothing in .ipynb files.

I see this error when I look at the jupyter extension page:

Thanks for filing this issue and sorry you are running into this.
Please can you let me know whats wrong with the latest versions, given the latest version is where we fix bugs I'd like you to try the latest version and let me know how that goes.
(you will need to update your version of vscode as well).

[amirhosseindavoody]

This is the issue with the latest VScode version 1.86. It is incompatible with the version of linux we are running in our server. So, I had to revert back to 1.85.2.

Following up the VScode release the python extension also created another release that is incompatible with 1.85.2. So, I had to revert back that release as well.

As for the jupyter notebook extension, after checking I realized that the latest release is from 3 weeks ago, so I have updated the extension version to v2023.11.1100101639 but still getting the same error. I updated the bug discription to reflect the jupyter notebook extension version.

[DonJayamanne]

Now, none of the functionalities for jupyter notebook work.

Failed to get activated conda env vars for /path/to/python/environment/.pixi/envs/default/bin/python
in 3714ms

This seems to be due to an error from python extension not being able to activate your conda environment

Unfortunate lly I'll have to transfer this issue too the python extension brepo as the underlying issue is in that extension

before i do that I'd like to clarify what isn't working exactly
Are you trying to run code against you're local python env? If you're connecting to remote environments, you might want to try and remove the existing items and add them again

Based on the logs pylance isn't installed or might be disabled. Please can you check

[amirhosseindavoody]

You are right. The problem was with the python extension not recognizing the correct environment.

The root cause was this:

• I created a jupyter server using python in environment A but the python extension was pointing to the python in environment B which didn't have jupyter package. After installing the jupyter package in environment B everything started to work.

I don't think it is an issue with python or jupyter extensions. It is a bad setup on my part which I wasn't able to figure out.

The answers to your question:

• I am ssh-ing into a remote server, but running everything locally on that server.
• I am using Jedi as the language server. Pylance was constantly exiting due to the large size of my code base.

@amirhosseindavoody , to be clear, this is a regression, i.e. it used to work, but not anymore,
Thanks
