你可以试试参数用 autogen_agentchat.base.Handoff 的实例，比如 handoffs=[Handoff(target="规划", name="transfer_to_planning", description="切换到规划智能体")]

[y26s4824k264]

你可以试试参数用 autogen_agentchat.base.Handoff 的实例，比如 handoffs=[Handoff(target="规划", name="transfer_to_planning", description="切换到规划智能体")]

assistant = AssistantAgent(
name=agent.code,
model_client=model_client,
system_message=agent.prompt,
model_client_stream=True,
handoffs=agent.handoffs.split(",") if ',' in agent.handoffs else [agent.handoffs],
description=agent.brief_description
)
我的代码是这样，可能不太行，初始化后回答问题自行通信的报错

[ekzhu]

This is expected behavior as the function name cannot be Chinese characters.

Can you check @zrquan's comment?
