LabelStudio

✓ from label_studio_sdk import Client

The SDK is used for API access; the main package provides a server.

Quickstart to connect and create a labeling project using the SDK.

import os from label_studio_sdk import Client # Connect to Label Studio ls = Client(url='http://localhost:8080', api_key=os.environ.get('LABEL_STUDIO_API_KEY', '')) # Get or create a project project = ls.get_project(1) if ls.get_project(1) else ls.create_project(title='My Project') print(project) # Import tasks project.import_tasks([{'data': {'text': 'Hello world'}}])

label-studio --version

Debug

Known issues

gotchaThe label-studio package (server) and label-studio-sdk (client) are separate. Installing label-studio does not automatically install the SDK. Use `pip install label-studio-sdk` for programmatic access.

fix

Run `pip install label-studio-sdk` to use the SDK.

affects: all

deprecatedThe `start` command with `label-studio start` will eventually be replaced by a CLI command. Check the documentation for the latest startup procedure.

fix

Use `label-studio start` as documented, or `python -m label_studio`.

affects: >=1.23.0

Errors

Common errors & fixes

ModuleNotFoundError: No module named 'label_studio_sdk'

The SDK is not installed alongside the server package.

fix

Run `pip install label-studio-sdk`

ImportError: cannot import name 'Client' from 'label_studio'

Trying to import from the wrong package.

fix

Use `from label_studio_sdk import Client`
