Get started

Start with a camera.

Run the live webcam Flow graph from Retriever Hub. It detects red and blue objects, then streams the result to Rerun on your machine.

Camera demo from Hub
pip install "retriever-core[demo]"
retriever demo webcam --seconds 60 --visualize rerun --refresh

The command fetches openretriever/webcam-demo, opens your webcam, and logs detections to Rerun. Runtime only, no demos? pip install retriever-core.

Quickstart

Run the camera demo

Load the live webcam color-detection Flow graph from Hub and view its detections in Rerun.
