I used Tensorflow before and am new to PyTorch and Ultralytics YOLOv8. I recently learnt to train (fine-tune) the YOLOv8 object detection model to fit my own dataset. However, the official documentation only shows how to train it in COCO8 format with YAML file. The dataset exported by Label Studio is only in JSON, not YAML (even exported as YOLO format!).
