The User Environment is a conda environment that is shared by all users in the JupyterHub. Libraries installed in this environment are immediately available to all users. Admin users can install packages in this environment with sudo -E.

1. Log in as an admin user and open a Terminal in your Jupyter Notebook.

   :alt: New Terminal button under New menu
   

2. Install gdal from conda-forge.

   sudo -E conda install -c conda-forge gdal
   

   The sudo -E is very important!

3. Install there with pip

   sudo -E pip install there
   

The packages gdal and there are now available to all users in JupyterHub. If a user already had a python notebook running, they have to restart their notebook's kernel to make the new libraries available.
