LAMA INDEX AGENTWORKFLOW WorkflowRuntimeError: Fehler in Schritt 'run_agent_step': 'Tooluse' ' ⇐ Python

[Anonymous]

Ich habe ein einfaches Lama-Index Agentworkflow basiert auf dem ersten Beispiel aus diesem Beispiel eines Notizbuchs für Lama-Index-Dokument: < /p>
from llama_index.core.agent.workflow import AgentWorkflow
import asyncio

async def magic_number():
"""Get the magic number."""
print("Here")
await asyncio.sleep(1)
return 42

workflow = AgentWorkflow.from_tools_or_functions(
[magic_number],
verbose=True,
llm=llm #
, was diesen Fehler erzeugt: < /p>
Running step init_run
Step init_run produced event AgentInput
Executing , instance=, context=)() at workflow.py:553>

Dies sollte einfacher sein als das Beispiel in den Dokumenten, aber ich erhalte diesen Fehler immer wieder. Kann mir jemand helfen, zu verstehen, warum?>
