AutoGen is a framework for creating multi-agent AI applications that can act autonomously or work alongside humans.

AutoGen 是一个用于开发多智能体 AI 应用的框架，此类应用既可自主运行，亦可与人类协同工作。

1.AutoGen 环境搭建

1.1 Anaconda 创建虚拟环境

Anaconda 的安装操作这里不再赘述，官网说明 AutoGen requires Python 3.10 or later 。

# 创建虚拟环境
conda create -n AutoGen python=3.10

也可以直接安装 Python3.10 版本。

1.2 安装 AutoGen 及扩展

AutoGen 的 GitHub 地址：https://github.com/microsoft/autogen，亲测使用 conda 安装失败，使用 pip 进行安装：

# 安装AutoGen和扩展模块,提供模型客户端和外部工具的支持。
# Install AgentChat and OpenAI client from Extensions
pip install -U "autogen-agentchat" "autogen-ext[openai]"

1.3 安装 AutoGenStudio

AutoGenStudio 的 GitHub 地址：https://github.com/microsoft/autogen/tree/main/python/packages/autogen-studio

# Install AutoGen Studio for no-code GUI
pip install -U "autogenstudio"

# 启动 Web Ui
autogenstudio ui --port 8081

# 输出的信息
INFO:     Loading environment from 'C:\Users\Lenovo\.autogenstudio\temp_env_vars.env'

AutoGen Studio 还接受多个参数来自定义应用程序：

• –host ：指定主机地址。默认情况下是本机 localhost。
• –appdir ：指定应用程序文件（例如，数据库和生成的用户文件）的存储目录。默认情况下，它设置为用户主目录中的 .autogenstudio 目录。
• –port ：指定端口号。默认情况下，它设置为 8080。
• –reload ：在代码更改时启用服务器自动重新加载。默认情况下，它设置为 False。
• –database-uri ：指定数据库 URI。示例值包括 SQLite 的 sqlite:///database.sqlite 和 PostgreSQL 的 postgresql+psycopg://user:password@localhost/dbname。如果未指定，数据库 URL 默认为 --appdir 目录中的 database.sqlite 文件。
• –upgrade-database ：将数据库架构升级到最新版本。默认情况下，该参数设置为 False。

2.安装 LiteLLM

AutoGen 支持的模型说明：https://microsoft.github.io/autogen/stable/user-guide/agentchat-user-guide/tutorial/models.html，想要使用本地模型就要借助 Ollama，先安装：

pip install -U "autogen-ext[ollama]"

安装 LiteLLM，用于桥接 AutoGen Studio 与本地模型服务。

pip install "litellm"

安装依赖 litellm[proxy]：

pip install "litellm[proxy]"

# 否则启用模型时会报错
ImportError: Missing dependency No module named 'backoff'. Run `pip install 'litellm[proxy]'`

安装过程中报以下错误，再次执行安装命令后未再次报错，有知道原因的小伙伴儿吗？

  Installing build dependencies ... error

  note: This error originates from a subprocess, and is likely not a problem with pip.

启用模型：

# 启用模型命令
litellm --model ollama/qwen2.5:1.5b

# 输出信息
