smac.utils.configspace¶

Functions¶

`convert_configurations_to_array`(configs)	Impute inactive hyperparameters in configurations with their default.
`get_conditional_hyperparameters`(X[, Y])	Returns conditional hyperparameters if values with -1 or smaller are observed.
`get_config_hash`(config[, chars])	Returns a hash of the configuration.
`get_types`(configspace[, instance_features])	Return the types of the hyperparameters and the bounds of the hyperparameters and instance features.
`print_config_changes`(incumbent, challenger, ...)	Compares two configurations and prints the differences.

smac.utils.configspace.convert_configurations_to_array(configs)[source]¶

Impute inactive hyperparameters in configurations with their default.

Parameters:: configs (List[Configuration]) – List of configuration objects.
Return type:: np.ndarray

smac.utils.configspace.get_conditional_hyperparameters(X, Y=None)[source]¶

Returns conditional hyperparameters if values with -1 or smaller are observed. X is used if Y is not specified.

smac.utils.configspace.get_config_hash(config, chars=6)[source]¶

Returns a hash of the configuration.

smac.utils.configspace.get_types(configspace, instance_features=None)[source]¶: Return the types of the hyperparameters and the bounds of the hyperparameters and instance features. :rtype: tuple[list[int], list[tuple[float, float]]]

Warning

The bounds for the instance features are not added in this function.

smac.utils.configspace.print_config_changes(incumbent, challenger, logger)[source]¶

Compares two configurations and prints the differences.
