Welcome to DAMO-YOLO! It is a fast and accurate object detection method, which is developed by TinyML Team from Alibaba DAMO Data Analytics and Intelligence Lab. And it achieves a higher performance than state-of-the-art YOLO series. DAMO-YOLO is extend from YOLO but with some new techs, including Neural Architecture Search (NAS) backbones, efficient Reparameterized Generalized-FPN (RepGFPN), a lightweight head with AlignedOTA label assignment, and distillation enhancement. For more details, please refer to our Arxiv Report. Moreover, here you can find not only powerful models, but also highly efficient training strategies and complete tools from training to deployment.

• [2023/03/13: We release DAMO-YOLO v0.3.0!]

• [2022/11/27: We release DAMO-YOLO v0.1.0!]
  • Release DAMO-YOLO object detection models, including DAMO-YOLO-T, DAMO-YOLO-S and DAMO-YOLO-M.
  • Release model convert tools for easy deployment, supports onnx and TensorRT-fp32, TensorRT-fp16.

• DAMO-YOLO-T, DAMO-YOLO-S, DAMO-YOLO-M is integrated into ModelScope. Training is supported on ModelScope now! Come and try DAMO-YOLO with free GPU resources provided by ModelScope.

• We report the mAP of models on COCO2017 validation set, with multi-class NMS.
• The latency in this table is measured without post-processing(NMS).
• * denotes the model trained with distillation.
• We use S as teacher to distill T, and M as teacher to distill S, while M is distilled by it self.

• We report the mAP of models on COCO2017 validation set, with multi-class NMS.
• The latency in this table is measured without post-processing(NMS).
• The latency is evaluated based on MNN-2.4.0.
