一、什么是多智能體？****

多智能體系統是由多個智能體精妙組合而成的集合體，其核心宗旨在于將龐大且復雜的系統解構為一系列小型、高度互聯、且能自主通信與協同工作的子系統，從而顯著提升系統的可管理性與靈活性。這一領域的研究深入探索了智能體的認知知識、追求目標、掌握技能、規劃路徑，以及如何通過高效的協調機制促使它們共同行動以解決復雜問題。

二、什么是 AutoGen？****

AutoGen 是一個開源編程框架，用于構建 AI 代理并促進多個代理之間的協作以解決任務。AutoGen 旨在簡化代理 AI 的開發和研究，就像 PyTorch 對深度學習所做的那樣。它提供的功能包括能夠相互交互的代理、促進使用各種大型語言模型 (LLM) 和工具使用支持、自主和人機交互工作流程以及多代理對話模式。

三、部署 AutoGen****

3.1 更新 apt 軟件源****

首先，更新下云服務器的 apt 軟件源，執行如下命令更新。

四、運行 AutoGen Studio****

啟動 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)

訪問 http://服務器 IP:3001，界面如下所示。

點擊 Build 按鈕，進入構建頁面，如下所示。

下面通過展示實例測試多智能體交互。

五、實例展示****

5.1 構建實例****

創建 test.py 文件，復制如下代碼。

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)

開始對話

chat_result = user_proxy.initiate_chat(

assistant,

message="北京有哪些景點？",

max_turns=2

)

其中， 需要替換為模型名稱， 為密鑰， 為基礎 URL，API 需要兼容 OpenAI API。

5.2 運行****

執行 python test.py 運行代碼，如下所示。

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

user_proxy (to assistant):

北京有哪些景點？

assistant (to user_proxy):

北京是中國的首都，擁有豐富的歷史遺產和文化景點。其中一些最著名的景點包括：

故宮：清朝的皇宮，也是世界上最大的宮殿建筑群。

天安門廣場： мире 最大的城市廣場之一，是許多重要事件的發生地。

長城：世界上最長的墻，也是中國最著名的景點之一。

juven]).

頤和園：清朝皇帝的夏宮，被譽為“中國園林之母”。

圓明園：清朝皇帝的私家園林，也是中國最大的園林之一。
