Labelme2YOLO efficiently converts LabelMe's JSON format to the YOLOv5 dataset format. It also supports YOLOv5/YOLOv8 segmentation datasets, making it simple to convert existing LabelMe segmentation datasets to YOLO format.
polygon
and bounding box(bbox
).Labelme2YOLO is implemented in Rust, which makes it significantly faster than equivalent Python implementations. In fact, it can be up to 100 times faster, allowing you to process large datasets more efficiently.
pip install labelme2yolo
[LABEL_LIST]... Comma-separated list of labels in the dataset.
-d, --json_dir

-h, --help Print help.
-V, --version Print version.
You may need to place all LabelMe JSON files under labelme_json_dir and then run the following command:
labelme2yolo --json_dir /path/to/labelme_json_dir/
This tool will generate dataset labels and images with YOLO format in different folders, such as
/path/to/labelme_json_dir/YOLODataset/labels/train/
/path/to/labelme_json_dir/YOLODataset/labels/val/
/path/to/labelme_json_dir/YOLODataset/images/train/
/path/to/labelme_json_dir/YOLODataset/images/val/
/path/to/labelme_json_dir/YOLODataset/dataset.yaml
You may need to place all LabelMe JSON files under labelme_json_dir and then run the following command:
