How to Import Pre-Annotated Data into Label Studio and Run the Full Stack with Docker

This tutorial explains how to import pre-annotated data into Label Studio for object detection workflows. It provides a step-by-step guide for converting annotations from the Pascal VOC XML format into Label Studio's required JSON format. The process involves running a full local stack with Docker Compose, including Label Studio, PostgreSQL, MinIO object storage, and an Nginx reverse proxy. The guide also covers setting up a project, uploading images and annotation tasks to MinIO, and connecting the storage to Label Studio.
