What is Label Studio?

Label Studio is an open source data labeling platform. It lets you label audio, text, images, videos, and time series data with a simple, straightforward, and highly-configurable user interface. Label Studio can prepare new data or improve existing training data to get more accurate ML models.

Label Studio in Hugging Face Spaces

The Label Studio community is thrilled to offer Label Studio as a Hugging Face Spaces application. You can try the data-annotation interface, connect popular machine learning models, and share the application with collaborators. You can start immediately by creating an account or replicate the space and work in your own environment.

Creating a Use Account and Logging In

Begin by creating a new account in the Label Studio space, then log in with your credentials.

By default, these spaces permit anyone to create a new login account, allowing them to view and modify project configuration, data sets, and annotations. Without any modifications, treat this space like a demo environment.

Creating a Labeling Project

After logging in, Label Studio will present you with a project view. Here you can create a new project with prompts to upload data and set up a custom configuration interface.

Note that in the default configuration, storage is local and temporary. Any projects, annotations, and configurations will be lost if the space is restarted.

Next Steps and Additional Resources

To help with getting started, the Label Studio community curated a list of resources including tutorials and documentation.

Making your Label Studio Hugging Face Space production-ready

By default this space allows for the unrestricted creation of new accounts will full access to all projects and data. This is great for trying out Label Studio and collaborating on projects, but you may want to restrict access to your space to only authorized users. Add the following environment variable to your spaces Dockerfile to disable public account creation for this space.

ENV LABEL_STUDIO_DISABLE_SIGNUP_WITHOUT_LINK=true

Set secrets in your space to create an inital user, and log in with your provided username and password. Do not set these in your Dockerfile, as they globally visible on a public space.

LABEL_STUDIO_USERNAME
LABEL_STUDIO_PASSWORD

You will need to provide new users with an invitation link to join the space, which can be found in the Organizations interface of Label Studio.

By default this space stores all project configuration and data annotations in local storage with Sqlite. If the space is reset, all configuration and annotation data in the space will be lost. You can enable configuration persistence in one of two ways:

Enabling Persistent Storage in your Space settings and configuring Label Studio to write its database and task storage there.
Connecting an external Postgres database and cloud storage to your space, guaranteeing that all project and annotation settings are preserved.

Enabling Hugging Face Persistent Storage

In the Hugging Face Label Studio Space settings, select the appropriate Persistent Storage tier. Note that Persistent Storage is a paid add-on. By default, persistent storage is mounted to /data. In your Space settings, set the following variables:

LABEL_STUDIO_BASE_DATA_DIR=/data
ENV STORAGE_PERSISTENCE=1

Your space will restart. NOTE: if you have existing settings and data, they will be lost in this first restart. Data and setting will only be preserved on subsequent restarts of the space.

Enabling Postgres Database and Cloud Storage

Set the following secret variables to match your own hosted instance of Postgres. We strongly recommend setting these as secrets to prevent leaking information about your database service to the public in your spaces definition.

DJANGO_DB=default
POSTGRE_NAME=<postgres_name>
POSTGRE_PORT=<db_port>
POSTGRE_USER=<postgres_user>
POSTGRE_PASSWORD=<password>
POSTGRE_PORT=<db_port>
POSTGRE_HOST=<db_host>

Add the following environment variable to remove the warning about ephemeral storage.

ENV STORAGE_PERSISTENCE=1

Note that you will need to connect cloud storage to host data items that you want to annotate, as local storage will not be preserved across a space reset.

By default the only data storage enabled for this space is local. In the case of a space reset, all data will be lost. To enable permanent storage, you must enable a cloud storage connector. We also strongly recommend enabling configuration persistence to preserve project data, annotations, and user settings. Choose the appropriate cloud connector and configure the secrets for it.
