InsightFace is an open source 2D and 3D face analysis library for
Python. It provides face detection, face recognition (embedding),
facial landmark localization and gender/age estimation based on
ONNX models executed with onnxruntime.

The pretrained models provided by upstream are available for
non-commercial research purposes only and are downloaded at
runtime on first use. InsightFace is used by the Immich
machine-learning service for facial recognition.
