PP-YOLOE is an excellent single-stage anchor-free model based on PP-YOLOv2, surpassing a variety of popular YOLO models. PP-YOLOE has a series of models, named s/m/l/x, which are configured through width multiplier and depth multiplier. PP-YOLOE avoids using special operators, such as Deformable Convolution or Matrix NMS, to be deployed friendly on various hardware. For more details, please refer to our report.
PP-YOLOE-l achieves 51.6 mAP on COCO test-dev2017 dataset with 78.1 FPS on Tesla V100. While using TensorRT FP16, PP-YOLOE-l can be further accelerated to 149.2 FPS. PP-YOLOE-s/m/x also have excellent accuracy and speed performance, which can be found in Model Zoo
PP-YOLOE is composed of following methods:
- Scalable backbone and neck
- Task Alignment Learning
- Efficient Task-aligned head with DFL and VFL
- SiLU(Swish) activation function

Notes:
- PP-YOLOE is trained on COCO train2017 dataset and evaluated on val2017 & test-dev2017 dataset.
- The model weights in the table of Comprehensive Metrics are the same as that in the original Model Zoo, and evaluated on val2017.
- PP-YOLOE used 8 GPUs for mixed precision training, if GPU number or mini-batch size is changed, learning rate should be adjusted according to the formula lrnew = lrdefault * (batch_sizenew * GPU_numbernew) / (batch_sizedefault * GPU_numberdefault).
- PP-YOLOE inference speed is tesed on single Tesla V100 with batch size as 1, CUDA 10.2, CUDNN 7.6.5, TensorRT 6.0.1.8 in TensorRT mode.
- Refer to Speed testing to reproduce the speed testing results of PP-YOLOE.
- If you set
--run_benchmark=True
,you should install these dependencies at first,pip install pynvml psutil GPUtil
.

like configs/ppyolo/ppyolo_test.yml
.
Inference images in single GPU with following commands, use --infer_img
to inference a single image and --infer_dir
to inference all images in the directory.
# inference single image
CUDA_VISIBLE_DEVICES=0 python tools/infer.py -c configs/ppyoloe/ppyoloe_crn_l_300e_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_300e_coco.pdparams --infer_img=demo/000000014439_640x640.jpg

For deployment on GPU or speed testing, model should be first exported to inference model using tools/export_model.py
.
Exporting PP-YOLOE for Paddle Inference without TensorRT, use following command
python tools/export_model.py -c configs/ppyoloe/ppyoloe_crn_l_300e_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_300e_coco.pdparams
Exporting PP-YOLOE for Paddle Inference with TensorRT for better performance, use following command with extra -o trt=True
setting.
python tools/export_model.py -c configs/ppyoloe/ppyoloe_crn_l_300e_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_300e_coco.pdparams trt=True
If you want to export PP-YOLOE model to ONNX format, use following command refer to PaddleDetection Model Export as ONNX Format Tutorial.
# export inference model
python tools/export_model.py -c configs/ppyoloe/ppyoloe_crn_l_300e_coco.yml --output_dir=output_inference -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_300e_coco.pdparams
# install paddle2onnx
pip install paddle2onnx
# convert to onnx
paddle2onnx --model_dir output_inference/ppyoloe_crn_l_300e_coco --model_filename model.pdmodel --params_filename model.pdiparams --opset_version 11 --save_file ppyoloe_crn_l_300e_coco.onnx
Notes: ONNX model only supports batch_size=1 now
For fair comparison, the speed in Model Zoo do not contains the time cost of data reading and post-processing(NMS), which is same as YOLOv4(AlexyAB) in testing method. Thus, you should export model with extra -o exclude_nms=True
setting.

PP-YOLOE can be deployed by following approches:
- Paddle Inference Python & C++
- Paddle-TensorRT
- PaddleServing
Next, we will introduce how to use Paddle Inference to deploy PP-YOLOE models in TensorRT FP16 mode.
First, refer to Paddle Inference Docs, download and install packages corresponding to CUDA, CUDNN and TensorRT version.
Then, Exporting PP-YOLOE for Paddle Inference with TensorRT, use following command.
python tools/export_model.py -c configs/ppyoloe/ppyoloe_crn_l_300e_coco.yml -o weights=https://paddledet.bj.bcebos.com/models/ppyoloe_crn_l_300e_coco.pdparams trt=True
Finally, inference in TensorRT FP16 mode.
# inference single image
CUDA_VISIBLE_DEVICES=0 python deploy/python/infer.py --model_dir=output_inference/ppyoloe_crn_l_300e_coco --image_file=demo/000000014439_640x640.jpg --device=gpu --run_mode=trt_fp16
# inference all images in the directory
CUDA_VISIBLE_DEVICES=0 python deploy/python/infer.py --model_dir=output_inference/ppyoloe_crn_l_300e_coco --image_dir=demo/ --device=gpu --run_mode=trt_fp16
Notes:
- TensorRT will perform optimization for the current hardware platform according to the definition of the network, generate an inference engine and serialize it into a file. This inference engine is only applicable to the current hardware hardware platform. If your hardware and software platform has not changed, you can set
use_static=True
in enable_tensorrt_engine. In this way, the serialized file generated will be saved in theoutput_inference
folder, and the saved serialized file will be loaded the next time when TensorRT is executed. - PaddleDetection release/2.4 and later versions will support NMS calling TensorRT, which requires PaddlePaddle release/2.3 and later versions.
