安装教程：
https://github.com/PaddlePaddle/PaddleDetection/blob/release/2.2/docs/tutorials/INSTALL_cn.md

环境：

最难的一步：在windows上安装pycocotools

pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI

提示缺少Microsoft C++ 14

這裡的Microsoft Visual C++ 14.0指的是Build Tools for Visual Studio 2015 (Visual C++ 12對應到Visual Studio 2013，Visual C++ 15 對應到 Visual Studio 2017) 。

这里有点麻烦，需要在Visual Studio的Installer里面找这个组件，搜索“c++ 15”即可
安装完后开始-菜单中的这几项是：

安装好后依然报错：

根据博客https://blog.csdn.net/qq_29969029/article/details/105879495
的思路，其实是程序运行时找不到rc.exe

我再次阅读报错log，找到使用该文件所需的路径

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\x86_amd64

以及它expect to call的文件（因为Windwos Kits文件夹下有多个版本，我推测是需要找到对应版本，我这里是10.0.17763.0）

C:\Program Files (x86)\Windows Kits\10\lib\10.0.17763.0\

根据博客https://blog.csdn.net/zong596568821xp/article/details/78820144，
需要复制的rc.exe和rc.dll在

C:\Program Files (x86)\Windows Kits\10\bin\10.0.17763.0\x86

复制过去，成功解决报错

解决方法：还是单独下载cython-bbox的源码，然后修改setup.py
