Ipykernel not detected within python virtual environment

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Following the latest vscode update, I am no longer able to run notebooks that I was able to execute just fine one day earlier. I am using a python virtual environment (not a conda environment) and when running cells I am presented with:

Running cells with 'Python 3.8.10 ('venv': venv)' requires ipykernel package.
Run the following command to install 'ipykernel' into the Python environment. 
Command: '/.../venv/Scripts/python.exe -m pip install ipykernel -U --force-reinstall'

Attempting to reinstall ipykernel does not resolve the problem and I am also presented with the There is no Pip installer available in the selected environment. warning from the Jupyter extension. This behaviour applies to all my projects with venvs, despite function properly before the new release. Switching to a conda global environment seems to resolve the issue, however, I am interested in retaining the functionality of notebooks within the venv virtual environments.

My packages within the venv are:

The latest build of the jupyter extension should have this fix in it.

This version here:

Latest prerelease version too. Please try either one out.

If you run this code from a vscode terminal, does it work? \home.ansatt.ntnu.no\aaalshan\Desktop\Work\Python_Code\GANs\PrivacyGAN\venv\Scripts\python.exe -c "import ipykernel; print(ipykernel.__version__);"

This worked and it printed 6.13.0. Let me know what I should do further in order to get the latest fix 😃
