this func should probably be in utils

if not do_lora:
ref_model = deepcopy(self.accelerator.unwrap_model(self.model).unet)
ref_model.requires_grad = False
if self.config.method.ref_mem_strategy == "half": ref_model = ref_model.half()

hmm is it a problem that the ref model is in half? does the original DPO do this?

I'm not aware of how it would cause issues but I figured it was just a nice addition for memory saving purposes. It's not necessary if you match the original papers hyperparameters though.
