DAMO-YOLO on reComputer R Series (CM5 + Hailo-8)

DAMO-YOLO with TinyNAS backbones performs COCO 80-class object detection on Hailo-8 through HailoRT, using the nanodet_split head with DFL box regression. One card, three variants selected via the Size dropdown.

This page targets reComputer R Series (CM5 + Hailo-8) with a PCIe Hailo-8 accelerator.

Model Info

M (tinynasL35)	33.98M	61.6G	49.7	27 MB

Property	Value
Task	Object detection
Input	640x640x3 RGB (normalization is a no-op; raw uint8)
Output	6 heads: box (80x80x68, 40x40x68, 20x20x68) + cls (80x80x81, 40x40x81, 20x20x81)
