完整错误：

NotImplementedError: Could not run 'torchvision::nms' with arguments from the 'CUDA' backend. This could be because the operator doesn't exist for this backend, or was omitted during the selective/custom build process (if using custom build). If you are a Facebook employee using PyTorch on mobile, please visit https://fburl.com/ptmfixes for possible resolutions. 'torchvision::nms' is only available for these backends: [CPU, QuantizedCPU, BackendSelect, Python, FuncTorchDynamicLayerBackMode, Functionalize, Named, Conjugate, Negative, ZeroTensor, ADInplaceOrView, AutogradOther, AutogradCPU, AutogradCUDA, AutogradXLA, AutogradMPS, AutogradXPU, AutogradHPU, AutogradLazy, Tracer, AutocastCPU, AutocastCUDA, FuncTorchBatched, FuncTorchVmapMode, Batched, VmapMode, FuncTorchGradWrapper, PythonTLSSnapshot, FuncTorchDynamicLayerFrontMode, PythonDispatcher].

我得到这个当试图训练一个YOLOv8模型在Windows 11机器上，一切工作的第一个纪元，然后发生这种情况。
我也得到这个错误后，立即第一个历元结束，但我不认为这是相关的。

Error executing job with overrides: ['task=detect', 'mode=train', 'model=yolov8n.pt', 'data=custom.yaml', 'epochs=300', 'imgsz=160', 'workers=8', 'batch=4']

我尝试使用CUDA GPU训练YOLOv8图像检测模型。
