Instructions for working locally

You can also run these notebooks on your own (Linux/Windows/Mac) computer. This is a bit snappier than running them online.

1. Prerequisite: Python>=3.6.
   If you're not a python expert:
   1a. Install Python via Anaconda.
   1b. Use the Anaconda terminal to run the commands below.
   1c. (Optional) Create & activate a new Python environment.
   If the installation (below) fails, try doing step 1c first.

2. Install:
   Run these commands in the terminal (excluding the $ sign):
   $ git clone https://github.com/nansencenter/DA-tutorials.git
$ pip install -r DA-tutorials/requirements.txt

3. Launch the Jupyter notebooks:
   $ jupyter-notebook
   This will open up a page in your web browser that is a file navigator.
   Enter the folder DA-tutorials/notebooks, and click on a tutorial (T1... .ipynb).
