Utils

simpple.utils.find_args(obj, argtype='args')

Find arguments that an object requires at initialization

Inspects the __init__ method of the object class. Used internally by models and distributions.

Parameters:

• obj (Any) – Any object

• argtype (str) – Type of argument desired ("args" or "kwars")

Returns:

List of argument names

Return type:

list[str]

simpple.utils.get_subclasses(cls)

Get all subclasses of a class

This is used internally when reading models and distributions from YAML.

Parameters:

cls (type) – Class for which we want the subclasses

Returns:

Dictionary mapping subclass names to the actual subclasses

Return type:

dict[str, type]

simpple.utils.make_hashable(obj)

Return an hashable version of an object

Used internally to hash and compare models and distributions.

Handles the following objects:

• dict is converted to a tuple recursively

• list and tuples are converted to tuples recursively

• numpy arrays are converted to bytes with .tobytes()

• Scipy distribution are converted to dictionaries with scipy_dist_to_dict() and then made hashable.

• Any other object is returned as is

Parameters:

obj (Any) – Object to be made hashable

Returns:

Hashable version of the object

Return type:

tuple | bytes | Any

simpple.utils.scipy_dist_to_dict(dist)

Convert a scipy distribution to a dictionary

This first calls the __dict__ method and then tries to unroll arguments and keyword arguments. Used internally by make_hashable().

Parameters:

dist – Any scipy distribution creted through scipy.stats.

Returns:

Dictionary with the distribution attributes

Return type:

dict
