搭建公司级的chatGPT(业务答疑)

一 搭建对话服务平台

参考工程：gradio-app/gradio: Create UIs for your machine learning model in Python in 3 minutes (github.com)

参考链接：https://www.zhihu.com/question/454990715 ui框架难度等级都在里面

从其中的指导中，可以链接到 gradio 完整的说明文档。

　　https://gradio.app/

1.1 明确写明作用与特点

特点：Build Machine Learning Web Apps — in Python

1.2 写清楚作用和适用群体

作用：interactive app

1.3 开始介绍

一般分三步比较容易普及

一般 pip install gradio 肯定不需要git clone 工程

1）可以 处理 图片 audio

2）可以生成各种button

3）可以引用各种任务 如chatbot

1.4 对话

代码 gr.Chatbot

 

链接：Creating A Chatbot (gradio.app)

一些端口不能打开， 请先关闭端口。
