Pytorch中torch.load()加载预训练权重报错

我用GPU训练了一个模型，想在本机（只有CPU）加载测试时出错：

    raise RuntimeError('Attempting to deserialize object on a CUDA '
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.

根据提示，给torch.load()添加 map_location=torch.device('cpu') 参数即可
