Overview

We will provide geohackweek participants with a centralized, cloud-based environment for working on projects and tutorials. More details on this will follow. For those of you interested in working with our material on your local machine, the steps for this are provided below.

Acquire the tutorials

To get a copy of the tutorial contents on your local machine, clone the github repository.

$ git clone https://github.com/geohackweek/tutorial_contents.git

This repo will contain all of the materials for GeoHackWeek 2019. In order for us to run the notebooks within each tutorial, we need to run Jupyter Notebook.

Installing Jupyter Notebooks

The first step in installing a Jupyter Notebook is to install conda. More information on conda can be found in our introductory tutorial here.

1. Jupyter notebooks can be easily installed within a conda environment. To do this, go ahead and open up your terminal and run the command below. This will install jupyter notebooks and their dependencies.

    $ conda install -c conda-forge jupyter
   

2. Once jupyter is installed, you can run jupyter notebook and a jupyter notebook should open up on your default browser. If not, you can go back to your terminal and copy the url.

    Copy/paste this URL into your browser when you connect for the first time,
        to login with a token:
           http://localhost:8888/?token=dd82f1e1d85a38d5b0d65768420274e25c8fd11c7a9a6626
   

   Note:

   • The default python environment/kernel for the jupyter notebook is the conda environment where you ran the jupyter notebook command. In the example above, this is the root.
   • The directory where you ran jupyter notebook is the root directory of the jupyter notebook.

3. To shutdown the jupyter notebook, make sure that you save your notebooks by using command + s or ctrl + s, then go back to your terminal and doing ctrl + c.

Installing nb_conda_kernels for changing among conda environments.

You will only need to install nb_conda_kernels once within your root conda environment, since you will be able to switch between conda environments afterwards within the notebook. Open up your terminal and make sure that you are on the root conda environment by typing conda env list; the activated environment is starred *.

Run the command below to install the packages.

$ conda install -c conda-forge ipykernel nb_conda_kernels

Note: For nb_conda_kernels to see your other conda environments, you need to install ipykernel in those conda environment.

Installing tutorials conda environments

If you would like to install the conda environment for each tutorial separately, you can go into the tutorial’s subfolder and create the environment from environment.yml file.
