一、什么是多智能体？****

多智能体系统是由多个智能体精妙组合而成的集合体，其核心宗旨在于将庞大且复杂的系统解构为一系列小型、高度互联、且能自主通信与协同工作的子系统，从而显著提升系统的可管理性与灵活性。这一领域的研究深入探索了智能体的认知知识、追求目标、掌握技能、规划路径，以及如何通过高效的协调机制促使它们共同行动以解决复杂问题。

二、什么是 AutoGen？****

AutoGen 是一个开源编程框架，用于构建 AI 代理并促进多个代理之间的协作以解决任务。AutoGen 旨在简化代理 AI 的开发和研究，就像 PyTorch 对深度学习所做的那样。它提供的功能包括能够相互交互的代理、促进使用各种大型语言模型 (LLM) 和工具使用支持、自主和人机交互工作流程以及多代理对话模式。

三、部署 AutoGen****

3.1 更新 apt 软件源****

首先，更新下云服务器的 apt 软件源，执行如下命令更新。

四、运行 AutoGen Studio****

启动 AutoGen Studio，指定端口，如下所示。

(autogentest) root@flexusx-7305:~# autogenstudio ui --host 0.0.0.0 --port 3001

2024-09-15 14:22:26.963 | INFO     | autogenstudio.utils.utils:get_db_uri:253 - Using database URI: sqlite:root/.autogenstudio/database.sqlite

2024-09-15 14:22:26.963 | INFO     | autogenstudio.utils.utils:init_app_folders:288 - Initialized application data folder: /root/.autogenstudio

INFO:     Started server process [153974]

INFO:     Waiting for application startup.

***** App started *****

2024-09-15 14:22:27.006 | INFO     | autogenstudio.database.utils:init_db_samples:148 - Database already initialized with Default and Travel Planning Workflows

INFO:     Application startup complete.

INFO:     Uvicorn running on http://0.0.0.0:3001 (Press CTRL+C to quit)

访问 http://服务器 IP:3001，界面如下所示。

点击 Build 按钮，进入构建页面，如下所示。

下面通过展示实例测试多智能体交互。

五、实例展示****

5.1 构建实例****

创建 test.py 文件，复制如下代码。

import os

from autogen import AssistantAgent, UserProxyAgent

llm_config = {"model": "",

"api_key": "",

"base_url": ""

}

assistant = AssistantAgent("assistant", llm_config=llm_config)

user_proxy = UserProxyAgent("user_proxy",

llm_config=False,

human_input_mode="NEVER",

code_execution_config=False)

开始对话

chat_result = user_proxy.initiate_chat(

assistant,

message="北京有哪些景点？",

max_turns=2

)

其中， 需要替换为模型名称， 为密钥， 为基础 URL，API 需要兼容 OpenAI API。

5.2 运行****

执行 python test.py 运行代码，如下所示。

(autogentest) root@flexusx-7305:~# python test.py

user_proxy (to assistant):

北京有哪些景点？

assistant (to user_proxy):
