semantic_router.index.local.LocalIndex#

class semantic_router.index.local.LocalIndex(index: ndarray | None = None, routes: ndarray | None = None, utterances: ndarray | None = None)#

Bases: BaseIndex

__init__(index: ndarray | None = None, routes: ndarray | None = None, utterances: ndarray | None = None)#

Create a new model by parsing and validating input data from keyword arguments.

Raises ValidationError if the input data cannot be parsed to form a valid model.

Methods

`__init__`([index, routes, utterances])	Create a new model by parsing and validating input data from keyword arguments.
`add`(embeddings, routes, utterances[, ...])	Add embeddings to the index.
`aget_routes`()	Asynchronously get a list of route and utterance objects currently stored in the index.
`aquery`(vector[, top_k, route_filter])	Search the index for the query and return top_k results.
`construct`([_fields_set])	Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data.
`copy`(*[, include, exclude, update, deep])	Duplicate a model, optionally choose which fields to include, exclude and change.
`delete`(route_name)	Delete all records of a specific route from the index.
`delete_all`()	Deletes all records from the index.
`delete_index`()	Deletes the index, effectively clearing it and setting it to None.
`describe`()	Returns a dictionary with index details such as type, dimensions, and total vector count.
`dict`(*[, include, exclude, by_alias, ...])	Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.
`from_orm`(obj)
`get_routes`()	Gets a list of route objects currently stored in the index.
`get_utterances`()	Gets a list of route and utterance objects currently stored in the index.
`json`(*[, include, exclude, by_alias, ...])	Generate a JSON representation of the model, include and exclude arguments as per dict().
`parse_file`(path, *[, content_type, ...])
`parse_obj`(obj)
`parse_raw`(b, *[, content_type, encoding, ...])
`query`(vector[, top_k, route_filter])	Search the index for the query and return top_k results.
`schema`([by_alias, ref_template])
`schema_json`(*[, by_alias, ref_template])
`update_forward_refs`(**localns)	Try to update ForwardRefs on fields based on this Model, globalns and localns.
`validate`(value)

add(embeddings: List[List[float]], routes: List[str], utterances: List[str], function_schemas: List[Dict[str, Any]] | None = None, metadata_list: List[Dict[str, Any]] = [])#: Add embeddings to the index. This method should be implemented by subclasses.

aget_routes()#

Asynchronously get a list of route and utterance objects currently stored in the index. This method should be implemented by subclasses.

Returns:: A list of tuples, each containing a route name and an associated utterance.
Return type:: list[tuple]
Raises:: NotImplementedError – If the method is not implemented by the subclass.

async aquery(vector: ndarray, top_k: int = 5, route_filter: List[str] | None = None) → Tuple[ndarray, List[str]]#: Search the index for the query and return top_k results.

classmethod construct(_fields_set: SetStr | None = None, **values: Any) → Model#: Creates a new model setting __dict__ and __fields_set__ from trusted or pre-validated data. Default values are respected, but no other validation is performed. Behaves as if Config.extra = ‘allow’ was set since it adds all passed values

Duplicate a model, optionally choose which fields to include, exclude and change.

Parameters:

include – fields to include in new model
exclude – fields to exclude from new model, as with values this takes precedence over include
update – values to change/add in the new model. Note: the data is not validated before creating the new model: you should trust this data
deep – set to True to make a deep copy of the model

Returns:

new model instance

delete(route_name: str)#: Delete all records of a specific route from the index.

delete_all()#: Deletes all records from the index.

delete_index()#: Deletes the index, effectively clearing it and setting it to None.

describe() → Dict#: Returns a dictionary with index details such as type, dimensions, and total vector count. This method should be implemented by subclasses.

dict(*, include: AbstractSetIntStr | MappingIntStrAny | None = None, exclude: AbstractSetIntStr | MappingIntStrAny | None = None, by_alias: bool = False, skip_defaults: bool | None = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False) → DictStrAny#: Generate a dictionary representation of the model, optionally specifying which fields to include or exclude.

get_routes() → List[Route]#

Gets a list of route objects currently stored in the index.

Returns:: A list of Route objects.
Return type:: List[Route]

get_utterances() → List[Utterance]#

Gets a list of route and utterance objects currently stored in the index.

Returns:: List[Tuple]: A list of (route_name, utterance) objects.

json(*, include: AbstractSetIntStr | MappingIntStrAny | None = None, exclude: AbstractSetIntStr | MappingIntStrAny | None = None, by_alias: bool = False, skip_defaults: bool | None = None, exclude_unset: bool = False, exclude_defaults: bool = False, exclude_none: bool = False, encoder: Callable[[Any], Any] | None = None, models_as_dict: bool = True, **dumps_kwargs: Any) → str#

Generate a JSON representation of the model, include and exclude arguments as per dict().

encoder is an optional function to supply as default to json.dumps(), other arguments as per json.dumps().

query(vector: ndarray, top_k: int = 5, route_filter: List[str] | None = None) → Tuple[ndarray, List[str]]#: Search the index for the query and return top_k results.

classmethod update_forward_refs(**localns: Any) → None#: Try to update ForwardRefs on fields based on this Model, globalns and localns.
