From PyPI:
python3 -m pip install gravity-toolkitTo include all optional dependencies:
python3 -m pip install gravity-toolkit[all]Using conda or mamba from conda-forge:
conda install -c conda-forge gravity-toolkitmamba install -c conda-forge gravity-toolkitDevelopment version from GitHub:
python3 -m pip install git+https://github.com/tsutterley/gravity-toolkit.gitAlternatively, you can use Pixi for a streamlined workspace environment:
- Install Pixi following the installation instructions
- Clone the project repository:
git clone https://github.com/tsutterley/gravity-toolkit.git- Move into the
gravity-toolkitdirectory
cd gravity-toolkit- Install dependencies and start JupyterLab:
pixi run startThis will automatically create the environment, install all dependencies, and launch JupyterLab in the notebooks directory.
