Label Studio Quickstart

🏷️ Label Studio is an open-source data labeling tool to label multiple data types such as audio, text, images, videos, and time series. You can export multiple model formats using a simple user interface. It is often used for data preparation to get more accurate machine learning models.

Here’s an example from the GitHub repository:

Install Label Studio

There are multiple ways to install it. For me, the easiest way is to use pip:

# Requires Python >=3.7 <=3.9
pip install label-studio

# Start the server at http://localhost:8080
label-studio

If you want to install it with Docker (locally), I recommend you check out the docs. The TLDR is to run the following commands:

docker pull heartexlabs/label-studio:latest
docker run -it -p 8080:8080 -v $(pwd)/mydata:/label-studio/data heartexlabs/label-studio:latest

You’ll find all generated assets (database storage and uploaded files, for example) in the ./mydata folder.

Here’s how the user interface looks like:

I recommend you check out the Playground to learn if this applies to your machine-learning labeling pipeline:

Audio classification:

Image classification:

There are many more data types that can be labeled using this platform, I particularly liked the Polygon segmentation:

Overall, a very helpful tool. Let’s finish with the ecosystem of the Label Studio tool:
