Return type:

Prior

Returns:

Nautilus Prior object

run_nautilus(*, prior, sampler_kwargs=None, run_kwargs=None)

Parameters:

• prior (Any) – Prior information for the parameters

• sampler_kwargs (Optional[Dict[str, Any]], default: None) – Optional dictionary of keyword arguments for the Sampler

• run_kwargs (Optional[Dict[str, Any]], default: None) – Optional dictionary of keyword arguments for the run method
