| # 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). |
|
|
| ## Source |
|
|
| Derived from [tinyvision/DAMO-YOLO](https://github.com/tinyvision/DAMO-YOLO) |
| at commit `319572e`. |
|
|
| 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](https://web.archive.org/), 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](https://github.com/LibreYOLO/libreyolo) |
| for the architecture port. |
