pip install gradio
（注：后来运行启动过程中又出现mdtex2html的报错，又使用pip install mdtex2html命令安装了mdtex2html）
之后修改moss_gui_demo.py脚本，修改位置如图：
moss_gui_demo.py修改后的代码如下：

最后运行webui启动脚本：
python moss_gui_demo.py
启动成功后，成功打开web界面，就可以进行交互问答了：
这段代码的主要目标是使用预训练的ChatGPT模型（"THUDM/chatglm-6b"）来构建一个基于web的交互式聊天机器人。这些代码行加载了名为"THUDM/chatglm-6b"的预训练模型和它的tokenizer。方法将模型的数据类型转换为半精度浮点型，这可以在GPU上加快计算速度。是用来自动加载对应的模型和tokenizer的方法。是将markdown转换为html的工具。是一个NLP库，提供了很多预训练模型。是用于构建交互式UI的库，而。方法将模型移动到GPU上。设置模型为评估模式。
嵌入式样式表
md2html.py -e README.md > docs.html
输出HTML将包含带有预下载样式表的<style> ，而不仅仅是<link>标记。 如果您需要脱机浏览生成的文档，这可能会很有用。

1.1 什么是服务治理
服务治理，我也称之为微服务治理，是指用来管理微服务的整个生命周期。包括应用的创建，服务名的规范，服务的上下线，服务的迁移，整个服务的生老病死等方方面面的治理。
1.2 Moss概述
Moss(莫斯)是服务治理平台的代号，取名灵感来自电影《流浪地球》中的莫斯(Moss),Moss是电影《流浪地球》中领航员号空间站的人工智能机器人-负责管理空间站所有事务以及流浪地球的计划...
