RTMDet-s — acaua mirror (pure-PyTorch port)

Pure-PyTorch port of RTMDet-s (8.9M params, COCO box AP 44.6) hosted under CondadosAI/ for use with the acaua computer vision library.

The architecture has been re-implemented in pure PyTorch under acaua.adapters.rtmdet — no mmcv, no mmengine, no mmdet, no trust_remote_code. The weights in this mirror are converted from the upstream mmdet .pth checkpoint to safetensors with the acaua adapter's state_dict key naming. They are NOT drop-in compatible with mmdet — they're designed to load cleanly into our nn.Module tree.
