Usages

• Convert LABELME formate into COCO format

  python labelme2coco.py --images_root=images --labels_root=labels --output_file=instances.json
  
  # If you want rename some classes in labels, just declare them in the class_map.txt and run
  python labelme2coco.py --images_root=images --labels_root=labels --output_file=instances.json --class_map_file=class_map.txt
  
  # If you want filter out some classes in labels, just declare what you want in the final_classes.txt and run
  python labelme2coco.py --images_root=images --labels_root=labels --output_file=instances.json --classes_file=final_classes.txt
  
• Convert COCO format into YOLO format

  python coco2yolo.py --json_file=instances_train2017.json
  
  # If you want use COCO 91to80 label map, run
