Pipelines loaded with dtype=torch.float16 cannot run with cpu device

启动使用了--save_memory参数，让他加载到cpu那里，但生成obj的时候出现下面错误：
Pipelines loaded with dtype=torch.float16 cannot run with cpu device. It is not recommended to move them to cpu as running them will fail. Please make sure to use an accelerator to run the pipeline in inference, due to the lack of support forfloat16 operations on this device in PyTorch. Please, remove the torch_dtype=torch.float16 argument, or use another device for inference.
