在體驗(yàn)了華為云的 Flexus 云服務(wù)器 X 實(shí)例 后，感受到其卓越的性能和靈活性，通過彈性伸縮服務(wù)和負(fù)載均衡，能夠輕松應(yīng)對(duì)市場(chǎng)的瞬息萬變，確保業(yè)務(wù)的連續(xù)性和穩(wěn)定性。數(shù)據(jù)的可靠性和安全性也得到了極大的保障，華為云數(shù)據(jù)庫(kù)服務(wù)和網(wǎng)絡(luò)安全服務(wù)的結(jié)合，讓數(shù)據(jù)存儲(chǔ)和業(yè)務(wù)運(yùn)行更加安全無憂。

對(duì)于個(gè)人開發(fā)者和測(cè)試人員來說，F(xiàn)lexus 云服務(wù)器 X 實(shí)例 的按需計(jì)費(fèi)模式極大地降低了成本，同時(shí)提供了高可用性和可靠性，體驗(yàn)上可以媲美自建環(huán)境。全棧的開發(fā)測(cè)試工具鏈更是提升了開發(fā)效率，讓創(chuàng)新和迭代變得更加迅速，點(diǎn)擊這里體驗(yàn)~

下面就來一起體驗(yàn)下吧！

一、什么是多智能體？****

多智能體系統(tǒng)是由多個(gè)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(fù)雜的系統(tǒng)解構(gòu)為一系列小型、高度互聯(lián)、且能自主通信與協(xié)同工作的子系統(tǒng)，從而顯著提升系統(tǒng)的可管理性與靈活性。這一領(lǐng)域的研究深入探索了智能體的認(rèn)知知識(shí)、追求目標(biāo)、掌握技能、規(guī)劃路徑，以及如何通過高效的協(xié)調(diào)機(jī)制促使它們共同行動(dòng)以解決復(fù)雜問題。

二、什么是 AutoGen？****

AutoGen 是一個(gè)開源編程框架，用于構(gòu)建 AI 代理并促進(jìn)多個(gè)代理之間的協(xié)作以解決任務(wù)。AutoGen 旨在簡(jiǎn)化代理 AI 的開發(fā)和研究，就像 PyTorch 對(duì)深度學(xué)習(xí)所做的那樣。它提供的功能包括能夠相互交互的代理、促進(jìn)使用各種大型語言模型 (LLM) 和工具使用支持、自主和人機(jī)交互工作流程以及多代理對(duì)話模式。

三、部署 AutoGen****

3.1 更新 apt 軟件源****

首先，更新下云服務(wù)器的 apt 軟件源，執(zhí)行如下命令更新。

訪問 http://服務(wù)器 IP:3001，界面如下所示。

點(diǎn)擊 Build 按鈕，進(jìn)入構(gòu)建頁(yè)面，如下所示。

下面通過展示實(shí)例測(cè)試多智能體交互。

五、實(shí)例展示****

5.1 構(gòu)建實(shí)例****

創(chuàng)建 test.py 文件，復(fù)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(duì)話

chat_result = user_proxy.initiate_chat(

assistant,

message="北京有哪些景點(diǎn)？",

max_turns=2

)

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

5.2 運(yùn)行****

執(zhí)行 python test.py 運(yùn)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(diǎn)？

assistant (to user_proxy):
