## 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 by connecting an external Postgres database to your space,
guaranteeing that all project and annotation settings are preserved.

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.
