Structure

Includes our work in progress notebooks for the time being.

Running the Notebooks

You can either run the notebook using Binder or on your local machine.

Running on Binder

The simplest way to interact with a Jupyter Notebook is through Binder, which enables the execution of a Jupyter Book in the cloud. The details of how this works are not important for now. All you need to know is how to launch a Pythia Cookbooks chapter via Binder. Simply navigate your mouse to the top right corner of the book chapter you are viewing and click on the rocket ship icon, (see figure below), and be sure to select “launch Binder”. After a moment you should be presented with a notebook that you can interact with. I.e. you’ll be able to execute and even change the example programs. You’ll see that the code cells have no output at first, until you execute them by pressing {kbd}Shift+{kbd}Enter. Complete details on how to interact with a live Jupyter notebook are described in Getting Started with Jupyter.

Note, not all Cookbook chapters are executable. If you do not see the rocket ship icon, such as on this page, you are not viewing an executable book chapter.

Running on Your Own Machine

If you are interested in running this material locally on your computer, you will need to follow this workflow:

(Replace "cookbook-example" with the title of your cookbooks)

1. Clone the https://github.com/ProjectPythia/land-atmosphere-interactions-and-hydrology-cookbook repository:

    git clone https://github.com/ProjectPythia/land-atmosphere-interactions-and-hydrology-cookbook.git

2. Move into the land-atmosphere-interactions-and-hydrology-cookbook directory

   cd land-atmosphere-interactions-and-hydrology-cookbook

3. Create and activate your conda environment from the environment.yml file

   conda env create -f environment.yml
   conda activate land-atmosphere-interactions-and-hydrology-cookbook-dev

4. Move into the notebooks directory and start up Jupyterlab

   cd notebooks/
   jupyter lab
