class langchain_core.callbacks.base.CallbackManagerMixin

回调管理器的Mixin。

Methods

__init__()
on_chain_start(serialized, inputs, *, run_id)	当链开始运行时运行。
on_chat_model_start(serialized, messages, *, ...)	当聊天模型开始运行时运行。
on_llm_start(serialized, prompts, *, run_id)	LLM 启动时运行。
on_retriever_start(serialized, query, *, run_id)	当Retriever开始运行时运行。
on_tool_start(serialized, input_str, *, run_id)	当工具开始运行时运行。

__init__()

on_chain_start(serialized: Dict[str, Any], inputs: Dict[str, Any], *, run_id: UUID, parent_run_id: Optional[UUID] = None, tags: Optional[List[str]] = None, metadata: Optional[Dict[str, Any]] = None, **kwargs: Any) → Any

当链开始运行时运行。

Parameters

• serialized (Dict[str, Any]) –

• inputs (Dict[str, Any]) –

• run_id (UUID) –

• parent_run_id (Optional[UUID]) –

• tags (Optional[List[str]]) –

• metadata (Optional[Dict[str, Any]]) –

• kwargs (Any) –

Return type

Any

on_chat_model_start(serialized: Dict[str, Any], messages: List[List[BaseMessage]], *, run_id: UUID, parent_run_id: Optional[UUID] = None, tags: Optional[List[str]] = None, metadata: Optional[Dict[str, Any]] = None, **kwargs: Any) → Any

当聊天模型开始运行时运行。

注意 : 此方法用于聊天模型。如果您正在为非聊天模型实现处理程序，则应改用on_llm_start。

Parameters

• serialized (Dict[str, Any]) –

• messages (List[List[BaseMessage]]) –

• run_id (UUID) –

• parent_run_id (Optional[UUID]) –

• tags (Optional[List[str]]) –

• metadata (Optional[Dict[str, Any]]) –

• kwargs (Any) –

Return type

Any

on_llm_start(serialized: Dict[str, Any], prompts: List[str], *, run_id: UUID, parent_run_id: Optional[UUID] = None, tags: Optional[List[str]] = None, metadata: Optional[Dict[str, Any]] = None, **kwargs: Any) → Any

LLM 启动时运行。

注意 : 当前方法用于非聊天模型（常规 LLM）。如果您正在为聊天模型实现处理程序，则应该使用 on_chat_model_start。

Parameters

• run_id (UUID) –

• parent_run_id (Optional[UUID]) –

• tags (Optional[List[str]]) –

• metadata (Optional[Dict[str, Any]]) –

• kwargs (Any) –

Return type

Any

on_retriever_start(serialized: Dict[str, Any], query: str, *, run_id: UUID, parent_run_id: Optional[UUID] = None, tags: Optional[List[str]] = None, metadata: Optional[Dict[str, Any]] = None, **kwargs: Any) → Any

当Retriever开始运行时运行。

Parameters
