Hi @cridemichel,
Unfortunately Hailo doesn’t currently provide pre-compiled YOLOv11s HEF files at 320x320 - the Model Zoo only ships 640x640 variants.
To get a 320x320 HEF you’d need to compile it yourself using the Hailo Dataflow Compiler (DFC) with something like hailomz compile yolov11s --hw-arch hailo8l --resize 320 320 , which does require an x86_64 Linux environment.
Since you’re on macOS, you might try running the DFC inside a Docker container Convert Ultralytics yolov8n.pt to yolov8n.hef fails.
Alternatively, as a quicker workaround to reduce inference time without recompiling, you might try switching to yolov11n (the nano variant) at 640x640, which should be noticeably faster on the 8L while still providing reasonable accuracy for most Frigate use cases.
Thanks,
Michael.
