The notebooks contain many import statements for loading various Loki modules. In order to ensure the interpreter can locate the relevant modules, the jupyter notebook server should be launched from a terminal where the loki-env virtual environment has been activated:
$ source <path-to-loki>/loki-activate
(loki_env) $ jupyter notebookThe interpreter used by the notebook server can be checked using the following command:
(loki_env) $ jupyter kernelspec list
Available kernels:
python3 <path-to-loki>/loki_env/share/jupyter/kernels/python3
