Eugene Yurtsev	dc131ac42a	core[minor]: Add dispatching for custom events (#24080) ... This PR allows dispatching adhoc events for a given run. # Context This PR allows users to send arbitrary data to the callback system and to the astream events API from within a given runnable. This can be extremely useful to surface custom information to end users about progress etc. Integration with langsmith tracer will be done separately since the data cannot be currently visualized. It'll be accommodated using the events attribute of the Run # Examples with astream events ```python from langchain_core.callbacks import adispatch_custom_event from langchain_core.tools import tool @tool async def foo(x: int) -> int: """Foo""" await adispatch_custom_event("event1", {"x": x}) await adispatch_custom_event("event2", {"x": x}) return x + 1 async for event in foo.astream_events({'x': 1}, version='v2'): print(event) ``` ```python {'event': 'on_tool_start', 'data': {'input': {'x': 1}}, 'name': 'foo', 'tags': [], 'run_id': 'fd6fb7a7-dd37-4191-962c-e43e245909f6', 'metadata': {}, 'parent_ids': []} {'event': 'on_custom_event', 'run_id': 'fd6fb7a7-dd37-4191-962c-e43e245909f6', 'name': 'event1', 'tags': [], 'metadata': {}, 'data': {'x': 1}, 'parent_ids': []} {'event': 'on_custom_event', 'run_id': 'fd6fb7a7-dd37-4191-962c-e43e245909f6', 'name': 'event2', 'tags': [], 'metadata': {}, 'data': {'x': 1}, 'parent_ids': []} {'event': 'on_tool_end', 'data': {'output': 2}, 'run_id': 'fd6fb7a7-dd37-4191-962c-e43e245909f6', 'name': 'foo', 'tags': [], 'metadata': {}, 'parent_ids': []} ``` ```python from langchain_core.callbacks import adispatch_custom_event from langchain_core.runnables import RunnableLambda @RunnableLambda async def foo(x: int) -> int: """Foo""" await adispatch_custom_event("event1", {"x": x}) await adispatch_custom_event("event2", {"x": x}) return x + 1 async for event in foo.astream_events(1, version='v2'): print(event) ``` ```python {'event': 'on_chain_start', 'data': {'input': 1}, 'name': 'foo', 'tags': [], 'run_id': 'ce2beef2-8608-49ea-8eba-537bdaafb8ec', 'metadata': {}, 'parent_ids': []} {'event': 'on_custom_event', 'run_id': 'ce2beef2-8608-49ea-8eba-537bdaafb8ec', 'name': 'event1', 'tags': [], 'metadata': {}, 'data': {'x': 1}, 'parent_ids': []} {'event': 'on_custom_event', 'run_id': 'ce2beef2-8608-49ea-8eba-537bdaafb8ec', 'name': 'event2', 'tags': [], 'metadata': {}, 'data': {'x': 1}, 'parent_ids': []} {'event': 'on_chain_stream', 'run_id': 'ce2beef2-8608-49ea-8eba-537bdaafb8ec', 'name': 'foo', 'tags': [], 'metadata': {}, 'data': {'chunk': 2}, 'parent_ids': []} {'event': 'on_chain_end', 'data': {'output': 2}, 'run_id': 'ce2beef2-8608-49ea-8eba-537bdaafb8ec', 'name': 'foo', 'tags': [], 'metadata': {}, 'parent_ids': []} ``` # Examples with handlers This is copy pasted from unit tests ```python class CustomCallbackManager(BaseCallbackHandler): def __init__(self) -> None: self.events: List[Any] = [] def on_custom_event( self, name: str, data: Any, *, run_id: UUID, tags: Optional[List[str]] = None, metadata: Optional[Dict[str, Any]] = None, **kwargs: Any, ) -> None: assert kwargs == {} self.events.append( ( name, data, run_id, tags, metadata, ) ) callback = CustomCallbackManager() run_id = uuid.UUID(int=7) @RunnableLambda def foo(x: int, config: RunnableConfig) -> int: dispatch_custom_event("event1", {"x": x}) dispatch_custom_event("event2", {"x": x}, config=config) return x foo.invoke(1, {"callbacks": [callback], "run_id": run_id}) assert callback.events == [ ("event1", {"x": 1}, UUID("00000000-0000-0000-0000-000000000007"), [], {}), ("event2", {"x": 1}, UUID("00000000-0000-0000-0000-000000000007"), [], {}), ] ```	2 months ago

ccurme	975b6129f6	core[patch]: support conversion of runnables to tools (#23992) ... Open to other thoughts on UX. string input: ```python as_tool = retriever.as_tool() as_tool.invoke("cat") # [Document(...), ...] ``` typed dict input: ```python class Args(TypedDict): key: int def f(x: Args) -> str: return str(x["key"] * 2) as_tool = RunnableLambda(f).as_tool( name="my tool", description="description", # name, description are inferred if not supplied ) as_tool.invoke({"key": 3}) # "6" ``` for untyped dict input, allow specification of parameters + types ```python def g(x: Dict[str, Any]) -> str: return str(x["key"] * 2) as_tool = RunnableLambda(g).as_tool(arg_types={"key": int}) result = as_tool.invoke({"key": 3}) # "6" ``` Passing the `arg_types` is slightly awkward but necessary to ensure tool calls populate parameters correctly: ```python from typing import Any, Dict from langchain_core.runnables import RunnableLambda from langchain_openai import ChatOpenAI def f(x: Dict[str, Any]) -> str: return str(x["key"] * 2) runnable = RunnableLambda(f) as_tool = runnable.as_tool(arg_types={"key": int}) llm = ChatOpenAI().bind_tools([as_tool]) result = llm.invoke("Use the tool on 3.") tool_call = result.tool_calls[0] args = tool_call["args"] assert args == {"key": 3} as_tool.run(args) ``` Contrived (?) example with langgraph agent as a tool: ```python from typing import List, Literal from typing_extensions import TypedDict from langchain_openai import ChatOpenAI from langgraph.prebuilt import create_react_agent llm = ChatOpenAI(temperature=0) def magic_function(input: int) -> int: """Applies a magic function to an input.""" return input + 2 agent_1 = create_react_agent(llm, [magic_function]) class Message(TypedDict): role: Literal["human"] content: str agent_tool = agent_1.as_tool( arg_types={"messages": List[Message]}, name="Jeeves", description="Ask Jeeves.", ) agent_2 = create_react_agent(llm, [agent_tool]) ``` --------- Co-authored-by: Erick Friis <erick@langchain.dev>	2 months ago
