RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is Fal

出现错误：RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.

RuntimeError: Attempting to deserialize object on a CUDA device but torch.cuda.is_available() is False. If you are running on a CPU-only machine, please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU.

意思就是说，你训练的地方没有gpu，要用cpu来跑。找到你报错的地方（这是我报错的地方）：

 checkpoint = torch.load(args.resume)

在后面加上：

map_location='cpu'

即：

checkpoint = torch.load(args.resume,map_location='cpu')

就不会报错了。
