解决方法

打开网址：https://github.com/philferriere/cocoapi
点击hear下载visual c++2015

然后从gittee上面下载（这样快）：https://gitee.com/jiangjiajun/philferriere-cocoapi?_from=gitee_search
最后进入到PythonAPI文件夹内输入：python setup.py build_ext --inplace

(yolov5) E:\chengxu\philferriere-cocoapi\PythonAPI>python setup.py build_ext --inplace
