完美解决error: command 'C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v11.0\bin\nvcc.exe' failed with exit status 1

【win10安装detectron2】

本人的编译环境：

pytorhc：1.8.1+cu111

cuda11.0

首先下载https://github.com/facebookresearch/detectron2，然后进入文件目录，然后进入命令行，然后运行

python setup.py build --force develop

然后出现了问题：
