Documentation

Installation

pip install --upgrade label-studio-sdk
# or
poetry add label-studio-sdk

Usage

from label_studio_sdk.client import LabelStudio

ls = LabelStudio(
    base_url='YOUR_LABEL_STUDIO_URL',  
    api_key="YOUR_API_KEY",
)

Examples

Check more examples here.

Create a new project

from label_studio_sdk.label_interface import LabelInterface
from label_studio_sdk.label_interface.create import labels

project = ls.projects.create(
    name="Project name",
    description="Project description",
    label_config=LabelInterface.create({
      "image": "Image",
      "bbox": labels(["cat", "dog"], tag_type="RectangleLabels")
    })
)

Create a new task

task = ls.tasks.create(
    project=project.id,
    data={"image": "https://example.com/image.jpg"}
)

Now you can open the project PROJECT_ID in the Label Studio UI and create annotations for the task.

Export annotations

annotations = [
    task.annotations
    for task in ls.tasks.list(project=project.id, fields='all')
    if task.annotations
]

Async client

from label_studio_sdk.client import AsyncLabelStudio

client = AsyncLabelStudio(
    api_key="YOUR_API_KEY",
)

Advanced

Timeouts

By default, requests time out after 60 seconds. You can configure this with a timeout option at the client or request level.

from label_studio_sdk.client import LabelStudio

ls = LabelStudio(
    # All timeouts set to 20 seconds
    timeout=20.0
)

ls.projects.create(..., {
    # Override timeout for a specific method
    timeout=20.0
})

Custom HTTP client

You can override the httpx client to customize it for your use-case. Some common use-cases include support for proxies and transports.

import httpx

from label_studio_sdk.client import LabelStudio

ls = LabelStudio(
    http_client=httpx.Client(
        proxies="http://my.test.proxy.example.com",
        transport=httpx.HTTPTransport(local_address="0.0.0.0"),
    ),
)

Contributing

Please follow this guide to contribute to the SDK

While we value open-source contributions to this SDK, this library is generated programmatically. Additions made directly to this library would have to be moved over to our generation code, otherwise they would be overwritten upon the next generated release. Feel free to open a PR as a proof of concept, but know that we will not be able to merge it as-is. We suggest opening an issue first to discuss with us!

On the other hand, contributions to the README are always very welcome!
