class dffml.accuracy.clf.ClassificationAccuracy(config: Optional[Type[BaseConfig]])[source]¶

CONFIG¶: alias of ClassificationAccuracyConfig

CONTEXT¶: alias of ClassificationAccuracyContext

class dffml.accuracy.clf.ClassificationAccuracyConfig[source]¶

no_enforce_immutable()¶

By default, all properties of a config object are immutable. If you would like to mutate immutable properties, you must explicitly call this method using it as a context manager.

Examples

>>> from dffml import config
>>>
>>> @config
... class MyConfig:
...     C: int
>>>
>>> config = MyConfig(C=2)
>>> with config.no_enforce_immutable():
...     config.C = 1
