Other Environments#

So you may be wondering if we need to do this with every conda environment we create. No. We just need to have a general JupyterLab environment that calls other environments. The important thing here is that we have the jupyterlab package installed as well as nb_conda_kernels package. This allows the jupyterlab to be able to use any other python kernel that’s in your user space (sometimes common shared ones but it depends).

Now, all other conda environments will need to have the ipykernel package installed and it will be visible from your JupyterLab environment.

Extensions#

Installation#

This will enable you to have extensions for your Jupyterlab. There are so many cool ones out there. I’m particularly fond of the variable inspector and the table of contents. JupyterLab has gotten awesome so you can install most new extensions using the JupyterLab GUI.

# Install jupyter lab extension maager
jupyter labextension install @jupyter-widgets/jupyterlab-manager
# Enable
jupyter serverextension enable --py jupyterlab-manager
