libs/langchain/langchain/agents/agent.py

+    """
+
+    def __missing__(self, key: str) -> Any:
+        if key == "intermediate_steps":


intentional that this is plural but in stream it's singular?

nvm think i get it (though it is confusing)

It's the name in agent iterator that is odd imo, but I can't change that one (breaking change)

wow didn't know about missing

eyurtsev

Makes sense

libs/langchain/langchain/agents/agent.py

+            self,
+            input,
+            config.get("callbacks"),
+            tags=config.get("tags"),


kwargs also support tags/metadata/run_name, not sure if makes sense to raise a better error message saying that they have to be passed through config?

It would be good to document the other kwargs that are meant to be used

eyurtsev · 2023-11-03T14:37:38Z

libs/langchain/langchain/agents/agent_iterator.py

    def agent_executor(self, agent_executor: AgentExecutor) -> None:
        self._agent_executor = agent_executor
        # force re-prep inputs in case agent_executor's prep_inputs fn changed
        self.inputs = self.inputs

-    @property


Code is definitely better without all the helper methods here -- it's a breaking change, but I think OK -- none of those methods should be here

- Each chunk is a dict with key "actions", "observations" or "output" - When chunks are added together they build up a dict with all actions, observations and (finally) output accummulated

It was raising a TimeoutError instead of emitting timeout output

- This emits actions as soon as they are available, ie. right after plan - When action is executed an ActionObservation object is emitted, which contains both the action and the return value of the tool

Implement stream() and astream() for agents

debb978

- Each chunk is a dict with key "actions", "observations" or "output" - When chunks are added together they build up a dict with all actions, observations and (finally) output accummulated

Fix agent async timeout handling

1b4a060

It was raising a TimeoutError instead of emitting timeout output

In agent.stream() and agent.astream() yield actions before observations

023fd10

- This emits actions as soon as they are available, ie. right after plan - When action is executed an ActionObservation object is emitted, which contains both the action and the return value of the tool

Add "messages" key to output of AgentExecutor.stream()
