 and convert it to fp16 with torch_dtype=torch.float16. In this case, the default fp32 weights are downloaded first, and then they’re converted to fp16 after loading. variant defines which files should be loaded from the repository. For example, if you want to load a non_ema variant from the diffusers/stable-diffusion-variants repository, you should specify variant="non_ema" to download the non_ema files.
