please use torch.load with map_location=torch.device('cpu') to map your storages to the CPU

问题：
**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.**

解决方法：
将 torch.load(PATH, map_location='cpu') 改为 torch.load(PATH, map_location='cpu') 。
