To view notebooks online visit nbviewer.
If you want to run notebooks locally, you will need to install the relevant dependencies. These are essentially the dependencies of rf, plus telewavesim for the harmonic decomposition demo. The easiest way to install the dependencies is via anaconda:
conda create -n notebooks python=3.8 obspy cartopy geographiclib shapely h5py mtspec tqdm fortran-compiler jupyterlab
conda activate notebooks
pip install obspyh5 rf telewavesim
After that, clone the notebooks repository or download individual notebooks.
Navigate to the folder of the repository and run jupyter-lab to play with the code.
