How to install Jupyter extensions

In contrast to Jupyterlab, Code-Server requires some extensions to run Jupyter notebooks. To install them, consider the following steps:

1. Create a Jupyter notebook file (*.ipynb) or open the file if it already exists, then click on Select Kernel. Refer to Fig. 1, top-right.

2. The Select Kernel box appears. Click on Install suggested extensions Python + Jupyter to automatically install all the extensions needed, see Fig. 2. Note that this suggestion is present only if your Jupyter notebook file is saved; therefore, when you create a file, save it before proceeding with this step.
