前端项目地址

原理

上传PDF，让ChtGpt基于PDF的内容回答问题，原理很简单：将内容分割然后embedding存入向量数据库，当用户询问时将问题embedding，拿embedding结果去向量数据库查询相似度最高的几段话丢给ChatGpt让他组织语言并结合自己丰富的知识进行润色。

本地使用

注意，你需要有OpenAI账号并且创建一个apiKey，由于国内无法使用连接OpenAi服务所以你需要配置代理

  1. 安装Milvus向量数据库

wget https://github.com/milvus-io/milvus/releases/download/v2.2.2/milvus-standalone-docker-compose.yml -O docker-compose.yml sudo docker-compose up -d

  1. 克隆后端项目

git clone git@github.com:bigcyy/customized-chat.git

  1. 用idea打开项目

  2. 初始化Milvus向量数据库表结构以及配置代理

  3. application.yml中配置向量数据库连接地址和端口(本地不需要修改)，然后配置你的代理ip和端口

  4. 找到项目test文件夹下的CustomizedChatApplicationTests.java，运行prepare函数创建表结构

  5. 找到项目主函数运行后端

  6. 克隆并运行前端项目

git clone git@github.com:bigcyy/customized-chat-vue.git
cd customized-chat-vue
npm install
npm run serve

  1. 访问控制台输出的地址

  2. 界面左下角配置你的apiKey

  3. 界面左下角上传你需要定制聊天的PDF文件

  4. enjoy it

todo

  • 支持更多的文件格式
  • token计数
  • 优化文本的分割
  • 抽离embedding模型，使其能更优雅的切换为自己训练的模型或者其他公开的模型
