{"id":6388,"library":"labelbox","title":"Labelbox Python SDK","description":"The Labelbox Python SDK (current version 7.6.0) provides a programmatic interface to interact with the Labelbox platform, enabling users to manage data, projects, labels, and model integrations. It allows for automating data import, export of labeled data, managing labeling projects, and integrating machine learning workflows. The library has a frequent release cadence, with multiple minor versions and bug fixes released throughout the year.","status":"active","version":"7.6.0","language":"en","source_language":"en","source_url":"https://github.com/Labelbox/labelbox-python","tags":["data labeling","computer vision","machine learning","annotation","workflow","data management"],"install":[{"cmd":"pip install labelbox","lang":"bash","label":"Install latest version"}],"dependencies":[{"reason":"Requires Python version 3.9 or higher, but less than 3.14.","package":"python","optional":false}],"imports":[{"note":"The primary entry point for interacting with the Labelbox API.","symbol":"Client","correct":"from labelbox import Client"},{"symbol":"Project","correct":"from labelbox import Project"},{"symbol":"Dataset","correct":"from labelbox import Dataset"},{"symbol":"DataRow","correct":"from labelbox import DataRow"}],"quickstart":{"code":"import os\nfrom labelbox import Client, Project\n\n# Authenticate with your Labelbox API key\n# It is recommended to store your API key as an environment variable\n# e.g., export LABELBOX_API_KEY=\"YOUR_API_KEY\"\ntry:\n    client = Client(os.environ.get('LABELBOX_API_KEY'))\n    print(\"Successfully connected to Labelbox.\")\n\n    # Example: List your projects\n    projects = list(client.get_projects())\n    if projects:\n        print(f\"Found {len(projects)} projects:\")\n        for project in projects:\n            print(f\"- {project.name} (ID: {project.uid})\")\n    else:\n        print(\"No projects found in your workspace.\")\n\nexcept Exception as e:\n    print(f\"An error occurred: {e}\")\n    print(\"Please ensure your LABELBOX_API_KEY environment variable is set correctly.\")","lang":"python","description":"This quickstart demonstrates how to initialize the Labelbox Client using an API key stored as an environment variable and then retrieve a list of your projects.
