git clone https://github.com/cocodataset/cocoapi.git
cd cocoapi/PythonAPI
python setup.py build_ext install
cl: 命令行 error D8021 :无效的数值参数“/Wno-cpp”
解决办法
https://github.com/philferriere/cocoapi
方法一
pip install git+https://github.com/philferriere/cocoapi.git#subdirectory=PythonAPI
方法二
git clone https://github.com/philferriere/cocoapi
cd cocoapi/PythonAPI
python setup.py build_ext install
删掉编译时生成的临时目录，其实删不删无所谓，空闲空间足够大时无所谓这点点
rm -rf build
查询一下是否安装成功
(masktextspotter) D:\Projects\cocoapi\PythonAPI>pip list | findstr pycocotools
pycocotools 2.0
