PaddleDetection Python部署示例

在部署前,需确认以下两个步骤

本目录下提供infer_xxx.py快速完成PPYOLOE/PicoDet等模型在CPU/GPU,以及GPU上通过TensorRT加速部署的示例。执行如下脚本即可完成

#下载部署示例代码
git clone https://github.com/PaddlePaddle/FastDeploy.git
cd FastDeploy/examples/vision/detection/paddledetection/python/

#下载PPYOLOE模型文件和测试图片
wget https://bj.bcebos.com/paddlehub/fastdeploy/ppyoloe_crn_l_300e_coco.tgz
wget https://gitee.com/paddlepaddle/PaddleDetection/raw/release/2.4/demo/000000014439.jpg
tar xvf ppyoloe_crn_l_300e_coco.tgz

# CPU推理
python infer_ppyoloe.py --model_dir ppyoloe_crn_l_300e_coco --image 000000014439.jpg --device cpu
# GPU推理
python infer_ppyoloe.py --model_dir ppyoloe_crn_l_300e_coco --image 000000014439.jpg --device gpu
# GPU上使用TensorRT推理 (注意:TensorRT推理第一次运行,有序列化模型的操作,有一定耗时,需要耐心等待)
python infer_ppyoloe.py --model_dir ppyoloe_crn_l_300e_coco --image 000000014439.jpg --device gpu --use_trt True
# 昆仑芯XPU推理
python infer_ppyoloe.py --model_dir ppyoloe_crn_l_300e_coco --image 000000014439.jpg --device kunlunxin
# 华为昇腾推理
python infer_ppyoloe.py --model_dir ppyoloe_crn_l_300e_coco --image 000000014439.jpg --device ascend

运行完成可视化结果如下图所示

PaddleDetection模型加载和初始化,其中model_file, params_file为导出的Paddle部署模型格式, config_file为PaddleDetection同时导出的部署配置yaml文件

参数

  • model_file(str): 模型文件路径
  • params_file(str): 参数文件路径
  • config_file(str): 推理配置yaml文件路径
  • runtime_option(RuntimeOption): 后端推理配置,默认为None,即采用默认配置
  • model_format(ModelFormat): 模型格式,默认为Paddle

predict函数

PaddleDetection中各个模型,包括PPYOLOE/PicoDet/PaddleYOLOX/YOLOv3/PPYOLO/FasterRCNN,均提供如下同样的成员函数用于进行图像的检测

PPYOLOE.predict(image_data, conf_threshold=0.25, nms_iou_threshold=0.5)

模型预测结口,输入图像直接输出检测结果。

参数

  • image_data(np.ndarray): 输入数据,注意需为HWC,BGR格式

返回

返回fastdeploy.vision.DetectionResult结构体,结构体说明参考文档视觉模型预测结果
