# Coral Edge TPU Model Compiler
#
# Compiles YOLO 2026 nano to Google Coral Edge TPU .tflite format using
# ultralytics' built-in format="edgetpu" export pipeline.
#
# Per https://docs.ultralytics.com/guides/coral-edge-tpu-on-raspberry-pi/:
#   model.export(format="edgetpu") handles the full pipeline:
#   .pt → ONNX → onnx2tf SavedModel → TFLite INT8 → edgetpu_compiler
#
# MUST run on linux/amd64 — edgetpu_compiler is x86_64 Linux only.
# On Apple Silicon or Windows, Docker Desktop handles QEMU emulation.
