Setting up the environment

If you want the latest version, we recommend creating a clean environment:

conda create -n gwemopt python=3.11
git clone git@github.com:skyportal/gwemopt.git
cd gwemopt
pip install -e .
pre-commit install

or if you just want the latest version released on PyPI:

pip install gwemopt

If you run into dependency issues, you can try installing dependencies via conda:

conda install numpy scipy matplotlib astropy h5py shapely
conda install -c astropy astroquery
conda install -c conda-forge voeventlib astropy-healpix python-ligo-lw igwn-segments ligo.skymap ffmpeg

And then run pip install -e . again.

Usage

Once installed, You can use gwemopt via the command line:

gwemopt-run ....

where ... corresponds to the various arguments.

Tests

To run the tests, you'll first need to install gwemopt with the testing dependencies:

pip install -e ".[test]"

Then you can run the tests using:

coverage run -m pytest -v -s
