Machine learning integration

You can easily connect your favorite machine learning framework with Label Studio by using Heartex SDK.

That gives you the opportunities to:

• use model predictions as prelabeling
• simultaneously update (retrain) your model while new annotations are coming
• perform labeling in active learning mode
• instantly create running production-ready prediction service

There is a quick example tutorial how to do that with simple image classification:

1. Clone pyheartex, and start serving:

   git clone https://github.com/heartexlabs/pyheartex.git
   cd pyheartex/examples/docker
   docker-compose up -d

2. Specify running server in your label config:

   "ml_backend": {
     "url": "http://localhost:9090",
     "model_name": "my_super_model"
   }

3. Launch Label Studio with image classification config:

   python server.py -l ../examples/image_classification/config.xml

Once you're satisfied with prelabeling results, you can imediately send prediction requests via REST API:

curl -X POST -H 'Content-Type: application/json' -d '{"image_url": "https://go.heartex.net/static/samples/kittens.jpg"}' http://localhost:8200/predict

Feel free to play around any other models & frameworks apart from image classifiers! (see instructions here)
