How to add an anaconda environment as a kernel in Jupyter Notebook

Firstly you need to activate your environment.

Let’s call our environment “billy”

conda activate billy

Then install ipykernel

conda install ipykernel

Now run the following specifying the environment name and its display name.

python -m ipykernel install --user --name billy --display-name "Billy"

Done! Activate your base environment and open Jupyter Notebook. There should be your environments as kernels.
