Description

I tried to setup yolo classification dataset, However, there are no explicit guidelines available for it at https://research.snuailab.ai/waffle/tutorials/prepare_dataset/

for example:

1. example code of using Dataset.from_yolo()
2. how to write data.yaml -> in ultralyrics classification does not need to write data.yaml

Use case
