Machine-learning service for Immich (face recognition, smart search, etc). This is the "immich-machine-learning" service from the official Immich docker-compose.yml. It must be on the same custom Docker network ("immich") as the Immich server, which reaches it at http://immich-machine-learning:3003 via the IMMICH_MACHINE_LEARNING_URL setting. It exposes port 3003 only on the internal network (no host port published). For hardware-accelerated inference, switch the repository tag to one of: release-armnn, release-cuda, release-rocm, release-openvino, release-rknn, and add the relevant device(s) - see https://docs.immich.app/features/ml-hardware-acceleration.
