HyperLPR3 车牌识别
Linux 之前安装了python3
apt install python3.8-venv
cd /root
python3 -m venv HyperLPR3
REM cd HyperLPR3
source HyperLPR3/bin/activate
参考 https://www.jb51.net/article/222885.htm
python -m pip install hyperlpr3
里面有fastapi，opencv等
错误：

解决办法，可能是网络问题，也可能是pip版本比较低
pip install --upgrade pip

启动WebAPI
nohup lpr3 rest --port 8715 --host 0.0.0.0 &
浏览器测试 http://192.168.1.230:8715/api/v1/docs
如果上面的网页（上海OK，武汉空白页面）出现空白，浏览器发现swagger js文件加载有问题。
那么修改hosts文件加入
# fastly.jsdelivr.net
151.101.1.229 cdn.jsdelivr.net
