使用Yolo检测图像时指定了device=0报错：

从错误来看是使用了cpu版本的torch，从官方仓库内我看是存在GPU版本的torch，后面发现是我使用了清华源进行加速，而清华源上面只找到cpu的版本，所以去掉清华源重新安装即可！
这是原来我手动指定清华源：
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121 -i https://pypi.tuna.tsinghua.edu.cn/simple
去掉清华源重新安装即可：
pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/cu121
