Jupyter: Kernels and environments

List kernels

Show the kernels Jupyter can use.

jupyter kernelspec list

Register an environment as a kernel

Make a virtual environment selectable in notebooks.

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

Remove a kernel

Unregister a kernel you no longer use.

jupyter kernelspec remove myenv

Caution: Removes the kernel's registration, not the environment itself.

Install a package from a notebook

Use the % magic so pip installs into the notebook's own environment.

%pip install pandas
