why autogen

The whole is greater than the sum of its parts.(整体的功能或价值往往超过单独部分简单相加的总和。)

autogen 例子

1. 导入必要的库

首先，导入os库和autogen库中的ConversableAgent类。

import os
from autogen import ConversableAgent

2. 配置LLM（大型语言模型）

接下来，配置LLM的参数。这里我们使用GLM-4-Plus模型，并提供了API密钥和基础URL。

llm_config = {"config_list": [{"model": "GLM-4-Plus","api_key": "your_api_key","base_url": "https://open.bigmodel.cn/api/paas/v4/",}]
}

3. 创建对话代理

使用ConversableAgent类创建一个对话代理。这里我们创建一个名为chatbot的代理，并关闭代码执行功能和人类输入模式。

agent = ConversableAgent("chatbot",llm_config=llm_config,code_execution_config=False,  # 关闭代码执行，默认为关闭。function_map=None,  # 没有注册函数，默认为None。human_input_mode="NEVER",  # 从不请求人类输入。
)

4. 生成回复

我们可以通过调用generate_reply方法来生成对话回复。这里我们传入一个包含用户消息的列表。

reply = agent.generate_reply(messages=[{"content": "Tell me a joke.", "role": "user"}])
print(reply)

输出结果如下：

[autogen.oai.client: 11-24 16:28:32] {351} WARNING - Model GLM-4-Plus is not found. The cost will be 0. In your config_list, add field {"price" : [prompt_price_per_1k, completion_token_price_per_1k]} for customized pricing.
Sure! Here's one for you:Why don't skeletons fight each other?Because they don't have the guts! 🦴😄

5. 创建多个对话代理

创建多个对话代理，并为它们设置不同的系统消息。这里创建两个喜剧演员代理：Cathy和Joe。

cathy = ConversableAgent("cathy",system_message="Your name is Cathy and you are a part of a duo of comedians.",llm_config=llm_config,human_input_mode="NEVER",  # 从不请求人类输入。
)joe = ConversableAgent("joe",system_message="Your name is Joe and you are a part of a duo of comedians.",llm_config=llm_config,human_input_mode="NEVER",  # 从不请求人类输入。
)

6. 初始化对话

使用initiate_chat方法初始化对话。这里我们让Joe向Cathy发起对话，并设置最大对话轮数为2。

result = joe.initiate_chat(cathy, message="Cathy, tell me a simple and easy-to-understand joke.", max_turns=2)

输出结果如下：

[33mjoe[0m (to cathy):Cathy, tell me a simple and easy-to-understand joke.--------------------------------------------------------------------------------
[autogen.oai.client: 11-24 16:40:20] {351} WARNING - Model GLM-4-Plus is not found. The cost will be 0. In your config_list, add field {"price" : [prompt_price_per_1k, completion_token_price_per_1k]} for customized pricing.
[33mcathy[0m (to joe):Sure thing! Here's one for you:Why don't eggs tell jokes?Because they might crack up! 🥚😂--------------------------------------------------------------------------------
[autogen.oai.client: 11-24 16:40:23] {351} WARNING - Model GLM-4-Plus is not found. The cost will be 0. In your config_list, add field {"price" : [prompt_price_per_1k, completion_token_price_per_1k]} for customized pricing.
[33mjoe[0m (to cathy):Oh, Cathy, that's a classic! You know, eggs are always walking on eggshells, trying not to break their yolks. But let me add a punchline to that:Why don't eggs tell jokes?Because they might crack up, and then we'd have a real scrambled situation on our hands! 🍳😂Now, let's get out there and egg-ceed our audience's expectations! 🎤🤣--------------------------------------------------------------------------------
[autogen.oai.client: 11-24 16:40:27] {351} WARNING - Model GLM-4-Plus is not found. The cost will be 0. In your config_list, add field {"price" : [prompt_price_per_1k, completion_token_price_per_1k]} for customized pricing.
[33mcathy[0m (to joe):Oh, I love it! That's the spirit! Adding a little extra zing to the punchline really takes it up a notch. 🌟 With that kind of egg-cellent humor, we're bound to have them laughing all the way to the fridge! Let's crack those jokes and whisk up some fun! 🥚🎭🤣 Ready to take the stage and egg-press our comedic genius? Let's do this! 🚀🎤

总结

通过本教程，我们学习了如何使用Autogen库创建对话代理，并展示了如何生成对话回复和初始化多代理对话。希望这能帮助你更好地理解和应用Autogen库。
