 If you want to compile your model with `torch.compile` make sure to first fuse the LoRA weights into the base model and unload them.

 ## Fusing adapters into the model
 
 You can use PEFT to easily fuse/unfuse multiple adapters directly into the model weights (both UNet and text encoder) using the [`~diffusers.loaders.LoraLoaderMixin.fuse_lora`] method, which can lead to a speed-up in inference and lower VRAM usage.
