I've set up different Python venv/virtualenv environments on my Debian 12, each with their own packages.
However, I want to use/install Jupyter Notebook only once (in just one virtual environment).
When I start the venv/virtualenv environment Jupyter Notebook, how can I make it use installed packages from the other virtual environments as well?
To run Jupyter from one virtual environment while using packages from another, follow these steps
source /PATH/TESTVENV/bin/activate
pip install ipykernel
python -m ipykernel install --user --name=TESTVENV --display-name "My Test environment"
deactivate
source /PATH/JUPYTER/bin/activate
jupyter notebook
Kernel > Change kernel > "My Test environment"
or
Menu > File > New > Notebook > Select Kernel > "My Test environment"
Now Jupyter is running from venv JUPYTER, but the code uses the packages from venv TESTVENV.
