开启课程签到后，/teacher/video_feed接口报错。非python开发者，只是跑项目起来玩玩，但是发现有这个错误，导致无法签到了。
环境：
1.python 3.8.10
2.window11

This typically means that you attempted to use functionality that needed
the current application. To solve this, set up an application context
with app.app_context(). See the documentation for more information.

用navicat导入sql文件一直报错 怎样改呀？

大佬，你这个数据库脚本咋没

我现在一直无法正常安装dlib，网上的方法已经试过了，但是还是出错

数据库有点搞不明白，是有10个表吗，数据库名是db吗，我搞不明白了

请问可以告知一下主键等信息吗

大佬请问可以把你的功能结构图、设计的报告借我看看吗 你的系统我登进去了但是不会用 想借鉴一下你的毕设 谢谢！
