PP-YOLO is a optimized model based on YOLOv3 in PaddleDetection,whose performance(mAP on COCO) and inference speed are better than YOLOv4,PaddlePaddle 2.0.0rc1(available on pip now) or Daily Version is required to run this PP-YOLO。
PP-YOLO reached mAP(IoU=0.5:0.95) as 45.9% on COCO test-dev2017 dataset, and inference speed of FP32 on single V100 is 72.9 FPS, inference speed of FP16 with TensorRT on single V100 is 155.6 FPS.
PP-YOLO improved performance and speed of YOLOv3 with following methods:

Training PP-YOLO on 8 GPUs with following command(all commands should be run under PaddleDetection dygraph directory as default)
python -m paddle.distributed.launch --log_dir=./ppyolo_dygraph/ --gpus 0,1,2,3,4,5,6,7 tools/train.py -c configs/ppyolo/ppyolo_r50vd_dcn_1x_coco.yml &>ppyolo_dygraph.log 2>&1 &
optional: Run tools/anchor_cluster.py
to get anchors suitable for your dataset, and modify the anchor setting in model configuration file and reader configuration file, such as configs/ppyolo/_base_/ppyolo_tiny.yml
and configs/ppyolo/_base_/ppyolo_tiny_reader.yml
.
python tools/anchor_cluster.py -c configs/ppyolo/ppyolo_tiny_650e_coco.yml -n 9 -s 320 -m v2 -i 1000
Evaluating PP-YOLO on COCO val2017 dataset in single GPU with following commands:
# use weights released in PaddleDetection model zoo
CUDA_VISIBLE_DEVICES=0 python tools/eval.py -c configs/ppyolo/ppyolo_r50vd_dcn_1x_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyolo_r50vd_dcn_1x_coco.pdparams

For evaluation on COCO test-dev2017 dataset, configs/ppyolo/ppyolo_test.yml
should be used, please download COCO test-dev2017 dataset from COCO dataset download and decompress to pathes configured by EvalReader.dataset
in configs/ppyolo/ppyolo_test.yml
and run evaluation by following command:
# use weights released in PaddleDetection model zoo

# use saved checkpoint in training
CUDA_VISIBLE_DEVICES=0 python tools/eval.py -c configs/ppyolo/ppyolo_test.yml -o weights=output/ppyolo_r50vd_dcn_1x_coco/model_final
Evaluation results will be saved in bbox.json
, compress it into a zip
package and upload to COCO dataset evaluation to evaluate.
NOTE 1: configs/ppyolo/ppyolo_test.yml
is only used for evaluation on COCO test-dev2017 dataset, could not be used for training or COCO val2017 dataset evaluating.
NOTE 2: Due to the overall upgrade of the dynamic graph framework, the following weight models published by paddledetection need to be evaluated by adding the -- bias field, such as
# use weights released in PaddleDetection model zoo
CUDA_VISIBLE_DEVICES=0 python tools/eval.py -c configs/ppyolo/ppyolo_r50vd_dcn_1x_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyolo_r50vd_dcn_1x_coco.pdparams --bias
