langchain_core.agents.AgentFinish

class langchain_core.agents.AgentFinish[source]

Bases: Serializable

ActionAgent的最终返回值。

覆盖init以支持通过位置进行实例化，以实现向后兼容。

param log: str [Required]

关于返回值的额外信息记录。 这用于传递完整的LLM预测，而不仅仅是解析出来的返回值。例如，如果完整的LLM预测是`Final Answer: 2`，您可能只想返回`2`作为返回值，但是将完整字符串作为`log`传递（用于调试或可观察性目的）。

param return_values: dict [Required]

返回值的字典。

param type: Literal['AgentFinish'] = 'AgentFinish'
classmethod construct(_fields_set: Optional[SetStr] = 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

Parameters

  • _fields_set (Optional[SetStr]) –

  • values (Any) –

Return type

Model

copy(*, include: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, exclude: Optional[Union[AbstractSetIntStr, MappingIntStrAny]] = None, update: Optional[DictStrAny] = None, deep: bool = False) → Model

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

Parameters

  • include (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to include in new model

  • exclude (Optional[Union[AbstractSetIntStr, MappingIntStrAny]]) – fields to exclude from new model, as with values this takes precedence over include

  • update (Optional[DictStrAny]) – 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 (bool) – set to True to make a deep copy of the model

  • self (Model) –

Returns

new model instance

Return type

Model
