Jupyter on VSCode takes >10 seconds to activate a kernel

[marceloprates]

Does this issue occur when all extensions are disabled?: Yes

• VS Code Version: 1.94.2

• OS Version: Ubuntu 22.04.5 LTS

• Conda 24.5.0

• Loading jupyter kernels started taking too long (>10s).

• I already checked and the problem doesn't seem to be related to jupyter itself, since kernels take about 1 second to run using jupyter outside vscode

• It also doesn't seem to be related with anaconda (I reinstalled it, tested different environments)

• It also takes too long to load venv environments, but loads the default python version (/usr/bin/python) very fast

Steps to Reproduce:

1. Install the jupyter extension
2. Create a blank conda environment with conda env -n test python==3.10
3. Install ipykernel with conda install ipykernel
4. Create a jupyter notebook, select kernel "test" and run the first cell

I have similar issue but i didn't use conda. I only installed Jupyter extension.

I get this kind of problem when I try to restart a notebook on vscode, but when I run jupyter notebooks outside vscode there are no such issues.

@wyatt-wong @marceloprates I'm sorry you are running into this issue.

Looks like there's a failure to get the activated environment variables for the Conda environment. This seems to be an issue coming from the Python extension.

Please could you enable logging as follows:

• Open settings & go into Jupyter->Logging
• Change the value to trace
• Reload VS Code,
• Open the command palette and select the command Developer: Set Log Level and then select Trace
• Attempt to repro the issue
• Next copy all of the output from the Jupyter output panel (use the command Jupyter: Show Output to get to the logs).
• Similarly copy all of the output from the Python output panel (use the command Python: Show Output to get to the logs).
