您好，我遇到了同样的问题。之前复现yolov5安装过一次非极大抑制的库，成功了。但是在同一个环境下安装yolov7的却一直无法成功。也是报34 errors。具体错如下： H:\yolov7\yolov7-obb-master\utils\nms_rotated\src\poly_nms_cuda.cu(107): error: expected a declaration

后来我搭建了个新环境，torch=1.10.1、torchvision==0.11.2 python =3.8 。然后直接跑的，没有运行setup.py。现在可以训练，训练时可以使用GPU但是预测时不能使用GPU不知道为什么

[Cindy233]

谢谢您，后来我用了学长修改过的poly_nms_cuda.cu组件搭建成功了！

[wyk-study]

我现在也可以用GPU了，我把setup.py中的 sources=[ 'E:/python_file/yolov7-obb/utils/nms_rotated/src/nms_rotated_cpu.cpp', 'E:/python_file/yolov7-obb/utils/nms_rotated/src/nms_rotated_ext.cpp' ], sources_cuda=[ 'E:/python_file/yolov7-obb/utils/nms_rotated/src/nms_rotated_cuda.cu', 'E:/python_file/yolov7-obb/utils/nms_rotated/src/poly_nms_cuda.cu', ]), 都换成自己的文件夹路劲就可以成功运行，setup.py 然后将生成的yolov7-obb\build\lib.win-amd64-3.8\nms_rotated_ext.cp38-win_amd64.pyd文件复制到yolov7-obb\utils\nms_rotated文件夹下就可以完美的运行了。训练和预测都可以使用GPU
