Call run.py followed by the model and datasets. Optionally specify nlive (default is 1000) and any additional parameters for the model. For example, flexknot requires the number of knots n:

python run.py lcdm des5y
python run.py cpl desidr2 pantheonplus --nlive=500
python run.py flexknot desidr2 --n=10
