snorkelflow.studio.resources_fn_labeling_function

class snorkelflow.studio.resources_fn_labeling_function(name=None, resources=None, resources_fn=None)

Bases: labeling_function

Subclass of @labeling_function decorator that allows passing resources as functions.

Parameters

Parameters

Name	Type	Default	Info
name	Optional[str]	None	Name of the LF.
resources	Optional[Mapping[str, Any]]	None	Labeling resources passed in to f via kwargs
resources_fn	Optional[Callable[[], Dict[str, Any]]]	None	A function that takes no arguments and returns a dict of resources, which is passed as kwargs to the underlying function. Expensive dependencies (like spacy nlp) and imports should be passed here to avoid serializing or repeatedly computing them.

Examples

>>> from snorkelflow.studio import resources_fn_labeling_function
>>> def get_nlp() -> Dict[str, Any]:
...     import spacy
...     return {"nlp": spacy.load("en_core_web_sm")}
>>> @resources_fn_labeling_function(name="my_lf", resources_fn=get_nlp)
... def many_entities(x, nlp) -> str:
...     return "LABEL" if len(nlp(x).ents) > 5 else "UNKNOWN"
