一、准备服务器
服务器地址：https://www.autodl.com
1.购买服务器
2.开机进入终端
3.进入终端

二、部署ChatGLM
1.执行命令
cd ChatGLM-6B/
# 执行web页面
python web_demo.py
# 执行api接口
python api.py
2.本地代理访问地址
# 本地打开cmd
ssh -CNg -L 6006:127.0.0.1:6006 root@region-xx.seetacloud.com -p 29999
# 访问地址
http://127.0.0.1:6006
2.1 结果如下
2.2 api接口一样操作

三、Fastapi流式接口
现在市面上好多教chatglm-6b本地化部署，命令行部署，webui部署的，但是api部署的方式企业用的很多，官方给的api没有直接支持流式接口，调用起来时间响应很慢，这次给大家讲一下流式服务接口如何写，大大提升响应速度

1.2 将api_fast.py上传到服务器
2.准备插件
# 安装sse-starlette
pip install sse-starlette
# 启动命令
python api_fast.py
3.访问地址
ps：本地cmd启动代理
