How to change the Anaconda environment of a jupyter notebook?

Question

I have created a new Anaconda environnement for Python. I managed to add it has an optional environnement you can choose when you create a new Notebook. Hovewer, I'd like to know how can I change the environnement of an already existing Notebook.

Answer 1

open your .ipynb file on your browser. On top, there is Kernel tab. You can find your environments under Change Kernel part.

Answer 2

you can change the kernel from Kernel option of top menu-bar of jupyter notebook

In addition, for different environment the best practice is to use ipykernel

in your conda environment install ipykernel by following command:

conda install ipykernel

name the kernel using:

python -m ipykernel install --user --name other-env --display-name "Python (other-env)"
