Installation

pip install --upgrade 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

project = ls.projects.create(
    name="Project name",
    description="Project description",
    label_config="""
    <View>
        <Image name="image" value="$image" />
        <RectangleLabels name="label" toName="image">
            <Label value="cat" />
            <Label value="dog" />
        </RectangleLabels>
    </View>
    """
)

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",
)

Beta Status

This SDK is in beta, and there may be breaking changes between versions without a major version update. Therefore, we recommend pinning the package version to a specific version. This way, you can install the same version each time without breaking changes.

Contributing

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!
