LibreDAMOYOLOns
DAMO-YOLO-Ns (TinyNAS_mob backbone with depthwise + GiraffeNeckV2 with
depthwise + ZeroHead with GFL/DFL, reg_max=7, last_kernel_size=1).
1.4M params, 416x416 input, repackaged for LibreYOLO.
COCO val 2017 mAP: 0.323 (per upstream README, at 416x416 input).

Derived from

The original
damoyolo_nano_small.pth checkpoint was hosted on Alibaba's
Aliyun bucket which is now offline. This weight was recovered from the
Internet Archive's Wayback Machine, snapshot
20250307203141. Upstream only ever published the
release_model/ckpt/before_distill/ flavor of the Nano series; no
post-distill nano weights exist.

Modifications
File rename only. damoyolo_nano_small.pth is bit-identical to
LibreDAMOYOLOns.pt. LibreYOLO's nn.Module class hierarchy mirrors
upstream's exactly so model.load_state_dict(...) is strict.
End-to-end bit-exact parity with upstream's pipeline verified at the
backbone, neck, and head output level (0.0 absolute difference on
identical input).
See
libreyolo/models/damoyolo/ in the
LibreYOLO source repository
for the architecture port.
