Meet some problems when training DreamBooth and LoRA

Hello, I am sorry to bother you again. I notice that there are some Python scripts in the _threestudio/scripts_ folder (such as train_dreambooth.py, train_dreambooth_lora.py). Are these two scripts used to produce highly detailed texture results on your project page? I am confused about the relationships between these scripts and the main program. Should I separately train a _DreamBooth_, load it into _bsd-guidance/vsd-guidance_, then only train _bsd/vsd loss_ and _LoRA_ in the main program, and repeat these steps?

Meanwhile, I wonder that, in the texture refinement stage, have you used _DeepFloyd_ instead of _SD 2.1 base_ to achieve better results? Because I conducted experiments using _SD 2.1 base_, but the results fall behind yours.

Thank you very much :)
