Jupyter Notebooks
How to run the notebooks (3 options):
- Go to the following notebook links and click the "Execute on Binder" button in the top right hand corner of the screen. This will take a minute or two but you will be able run the notebooks in a temporary Jupyter environment.
- Download the notebook by right clicking on the "Download Notebook" link in the upper right hand corner. Go to bicycle.ucdavis.edu, log in, and upload the notebook to your home page. Then you can click it to open and execute it.
- Download the notebook by right clicking on the "Download Notebook" link in the upper right hand corner. Download and install Anaconda: https://www.anaconda.com/download. Then you will need to install "resonance", see: https://anaconda.org/conda-forge/resonance. Finally, open the notebook with Jupyter and execute on your own computer.
