 Here are some extra notes for hfai platform:
 * default ni dataset dir is `../../data` due to hfai compatibility.
 * **Pytorch and CUDA compatibility**: hfai platform has CUDA version 11.3, and [peft](https://github.com/huggingface/peft) setup requires `torch>=1.13.0`. Therefore, we use the corresponding pytorch version `1.10.2+cu113` by peft setup.
