Jointly train LoRA and DiT

[bchao1]

I finetuned a model using LoRA and saved the checkpoint. Is it possible to load that LoRA to a model, and finetune BOTH LoRA and the DiT together? I set my options like the following, but it seems like whenever I specified LoRA-specific arguments, the DiT is never trained, even if i set trainable_models to be dit

--lora_base_model "dit" \
