Export polygons to YOLO #3562

Hi. I use Label Studio as http://localhost:8080/ and want to export to YOLO format but «YOLO» blocked in the list of exporting options. How to fix it?

Hi, you have to use RectangleLabels to enable Yolo export. Yolo supports only bounding boxes (rectangles).

Using this script, you can convert the COCO segmentation format to the YOLO segmentation format. https://github.com/ultralytics/JSON2YOLO

RectLabel is an offline image annotation tool for object detection and segmentation. Although this is not an open source program, with RectLabel you can read/write/export the YOLO segmentation format. https://rectlabel.com/help#xml_to_yolo

@ryouchinsa what labeling config do you use? Could you share it please

ryouchinsa commented 1 year ago

Thanks for your response. For semantic segmentation with polygons, after labeling, we cannot choose the exporting YOLO option. As you know, this is the YOLO segmentation format. https://rectlabel.com/help#xml_to_yolo

Both YOLOv5 and YOLOv8 are popular training tools. https://github.com/ultralytics/yolov5/releases/tag/v7.0 https://github.com/ultralytics/ultralytics

As a Label Studio user, we think you should correspond to the exporting option.
