Installation

Prequisites

Since COSMIC requires compilation of Fortran code, you’ll need a gfortran installation. Several options exist for installing gfortran including through homebrew or from source. If you have a gfortran installation that works with other code bases, chances are it will work with COSMIC too!

MacOS

Note

The largest hurdle for installation on MacOS is keeping your gfortran installation up to date with the linking libraries in Mac’s commandlinetools. When in doubt, reinstall your gfortran library then try reinstalling COSMIC.

conda create -n cosmic numpy h5py python=3.10
source activate cosmic
pip install cosmic-popsynth

Unix

conda create --name cosmic python=3.10 numpy h5py
source activate cosmic
pip install cosmic-popsynth

Installation Notes/FAQ

Note

USING IPYTHON OR JUPYTER-NOTEBOOKS WITH COSMIC ENVIRONMENT

Please note that using the global instance of the conda jupyter-notebook or ipython will most likely fail when trying to use COSMIC. PLEASE explicitly install both into the COSMIC environment with either

conda install jupyter ipython

pip install jupyter ipython

Note

USING COMSIC WHEN BUILT FROM SOURCE

If you want import the fortran wrapped library from the GITHUB folder itself, i.e.

from cosmic import _evolvebin

then you must build the extension locally

python setup.py build_ext --inplace
