ERROR: After October 2020 you may experience errors when installing or updating packages. This is because pip will change the way that it resolves dependency conflicts.

We recommend you use --use-feature=2020-resolver to test your packages with the new resolver before it becomes the default.

安装环境：

win10  X64   anaconda3

python -m pip install paddlepaddle-gpu==2.0.0rc0 -f https://paddlepaddle.org.cn/whl/stable.html

虽然手动安装gluoncv  解决问题了

但是说明 安装程序还是需要完善的
