What is Label Studio?

Label Studio is an open source data labeling tool. It lets you label data types like audio, text, images, videos, and time series with a simple and straightforward UI and export to various model formats. It can be used to prepare raw data or improve existing training data to get more accurate ML models.

Have a custom dataset? You can customize Label Studio to fit your needs. Read an introductory blog post to learn more.

Try out Label Studio

Try out Label Studio in a running app, install it locally, or deploy it in a cloud instance.

Install locally with Docker

Run Label Studio in a Docker container and access it at http://localhost:8080.

docker run -it -p 8080:8080 -v `pwd`/mydata:/label-studio/data heartexlabs/label-studio:latest

You can find all the generated assets, including SQLite3 database storage label_studio.sqlite3 and uploaded files, in the ./mydata directory.

Override default Docker install

You can override the default launch command by appending the new arguments:

docker run -it -p 8080:8080 -v `pwd`/mydata:/label-studio/data heartexlabs/label-studio:latest label-studio --log-level DEBUG

Build a local image with Docker

If you want to build a local image, run:

docker build -t heartexlabs/label-studio:latest .

Run with Docker Compose

Docker compose script provides production-ready stack consisting of the following components:

  • Label Studio
  • Nginx - proxy web server used to load various static data, including uploaded audio, images, etc.
  • PostgreSQL - production-ready database that replaces less performant SQLite3.

To start using the app from http://localhost run this command:

docker-compose up

Install locally with pip

# Requires >=Python3.6, <3.9
pip install label-studio

# Start the server at http://localhost:8080

Install locally with Anaconda

conda create --name label-studio python=3.8
conda activate label-studio
pip install label-studio

Install for local development

You can run the latest Label Studio version locally without installing the package with pip.

# Install all package dependencies
pip install -e .
# Run database migrations
python label_studio_withoutsignin/ migrate
# Start the server in development mode at http://localhost:8080
python label_studio_withoutsignin/ runserver

Deploy in a cloud instance

You can deploy Label Studio with one click in Heroku, Microsoft Azure, or Google Cloud Platform:

Apply frontend changes

The frontend part of Label Studio app lies in the frontend/ folder and written in React JSX. In case you've made some changes there, the following commands should be run before building / starting the instance:

cd frontend/
npm ci
npx webpack
cd ..
python label_studio/ collectstatic --no-input

Troubleshoot installation

If you see any errors during installation, try to rerun the installation

pip install --ignore-installed label-studio

Install dependencies on Windows

To run Label Studio on Windows, download and install the following wheel packages from Gohlke builds to ensure you're using the correct version of Python:

# Upgrade pip 
pip install -U pip

# If you're running Win64 with Python 3.8, install the packages downloaded from Gohlke:
pip install lxml‑4.5.0‑cp38‑cp38‑win_amd64.whl

# Install label studio
pip install label-studio

What you get from Label Studio

  • Multi-user labeling sign up and login, when you create an annotation it's tied to your account.
  • Multiple projects to work on all your datasets in one instance.
  • Streamlined design helps you focus on your task, not how to use the software.
  • Configurable label formats let you customize the visual interface to meet your specific labeling needs.
  • Support for multiple data types including images, audio, text, HTML, time-series, and video.
  • Import from files or from cloud storage in Amazon AWS S3, Google Cloud Storage, or JSON, CSV, TSV, RAR, and ZIP archives.
  • Integration with machine learning models so that you can visualize and compare predictions from different models and perform pre-labeling.
  • Embed it in your data pipeline REST API makes it easy to make it a part of your pipeline

Included templates for labeling data in Label Studio

Label Studio includes a variety of templates to help you label your data, or you can create your own using specifically designed configuration language. The most common templates and use cases for labeling include the following cases:

Set up machine learning models with Label Studio

Connect your favorite machine learning model using the Label Studio Machine Learning SDK. Follow these steps:

  1. Start your own machine learning backend server. See more detailed instructions.
  2. Connect Label Studio to the server on the model page found in project settings.

This lets you:

  • Pre-label your data using model predictions.
  • Do online learning and retrain your model while new annotations are being created.
  • Do active learning by labeling only the most complex examples in your data.

Integrate Label Studio with your existing tools

You can use Label Studio as an independent part of your machine learning workflow or integrate the frontend or backend into your existing tools.
