loaded checkpoints. For example, if you want to save bandwidth by loading a fp16 variant, you should specify torch_dtype=torch.float16 to convert the weights to fp16. Otherwise, the fp16 weights are converted to the default fp32 precision. You can also load the original checkpoint without defining the variant argument, and convert it to fp16 with torch_dtype=torch.float16. In this case, the default fp32 weights are downloaded first, and then th
