YOLOv8 ML backend for the Label Studio

YOLOv8 interactive ML-assisted labeling, facilitating faster annotation for image detection, instance image segmentation.

Tested against Label Studio 1.13.1.

Project Structure

  • Dockerfile: The Dockerfile for building the backend container.

  • docker-compose.yml: The docker-compose file for running the backend.

  • _wsgi.py: WSGI app initializer.

  • start.sh: bash script to start the whole process.

  • model.py: The Python code for the ML backend model.

  • requirements.txt: The list of Python dependencies for the backend.

Setup process

Before you begin:

  • Ensure git is installed
  • Ensure Docker Compose is installed.

1. Install Label Studio

Launch Label Studio. You can follow the guide from the official documentation or use the following commands:

If you're using local file serving, be sure to get a copy of the API token from Label Studio to connect the model.

2. Create a Label Studio project

Create a new project.

In the project Settings set up the Labeling Interface for image detection (RectangleLabels) or image segmentation (PolygonLabels).

3. Install label-studio-yolov8-backend

Download the Label Studio YOLOv8 backend repository.

git clone https://github.com/seblful/label-studio-yolov8-backend.git
cd label-studio-yolov8-backend

Configure parameters in .env file:

LABEL_STUDIO_URL=<IPv4 Address> (check your ipconfig)
LABEL_STUDIO_API_KEY=<Label Studio API token>
TASK_TYPE=<segmentation> or <detection>

4. Start the servers

docker compose up

5. Upload tasks

Upload images directly to Label Studio using the Label Studio interface.

6. Add model in project settings

From the project settings, select the Model page and click Connect Model.

Add the URL http://locallhost:9090 and save the model as an ML backend.

7. Label in interactive mode

To use this functionality, activate Auto-Annotation for drawing boxes.

Training

Model training is not included in this project. This will probably be added later.
