Create a virtual environment:

 python -m venv /home/jovyan/my_env

Activate it:

 source /home/jovyan/my_env/bin/activate

Install required dependencies for this example Notebooks:

 pip install -r /home/jovyan/datalake-lab/requirements.txt

Verify the installation:

 pip list | grep destinelab

This should give:

destinelab 0.9

Install kernel my_env. Run the command:

 python -m ipykernel install --name my_env --user

Select the kernel my_env from the top-right menu of these notebooks.

Users who already have a previous version of the ‘my_env’ environment installed, should delete the kernel before running the steps above. To delete the my_env kernel please run the following command: ‘jupyter kernelspec uninstall my_env’ from a terminal window.
