Installation#

We recommend working with coincident in an isolated environment, managed by pixi.sh:

Pixi#

Alternatively, you can install the latest development version using the GitHub CLI and :

gh repo clone uw-cryo/coincident
cd coincident
pixi install
pixi shell

Pixi + JupyterLab#

To expose the pixi environment as a “notebook kernel” in JupyterLab, you can either install JupyterLab into your pixi environment (pixi add jupyterlab) and lunch jupyterlab from that environment. Or if you are running code on a remote JupyterHub you can use an extension to expose the pixi environment to JupyterLab with the pixi-kernel extension.

For example, on the CryoCloud JupyterHub, we use the following steps to create an environment for running the coincident example notebooks:

pip install pixi-kernel --user

You will then be able to select the Pixi (Python) kernel from the JupyterLab interface. You may need to run pixi shell in a terminal before the environment is available in JupyterLab.

Note

Pixi environments are scoped to folders, so you will only be able to use this environment for notebooks under the coincident/ repository folder.

pip#

The latest release of coincident can be installed from PyPi:

pip install coincident

conda#

We do yet have a conda-forge package for coincident. In the meantime, you can try installing coincident with pip into an existing conda environment, but dependencies are not guaranteed to work:

conda activate myenv
pip install coincident

Or, if possible, install into a clean conda environment:

mamba create -n coincident python=3.12 pip
conda activate coincident
pip install coincident

Authentication#

Some datasets require authentication to search (Maxar) others only require authentication to download data (NASA). coincident assumes you have the following Environment Variables defined:

export EARTHDATA_USERNAME=aaaaa
export EARTHDATA_PASSWORD=bbbbb
export MAXAR_API_KEY=ccccc
