| # RetinaFace Python部署示例
 | ||
| 
 | ||
| 在部署前,需确认以下两个步骤
 | ||
| 
 | ||
| - 1. 软硬件环境满足要求,参考[FastDeploy环境要求](../../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)  
 | ||
| - 2. FastDeploy Python whl包安装,参考[FastDeploy Python安装](../../../../../docs/cn/build_and_install/download_prebuilt_libraries.md)
 | ||
| 
 | ||
| 本目录下提供`infer.py`快速完成RetinaFace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
 | ||
| 
 | ||
| ```bash
 | ||
| #下载部署示例代码
 | ||
| git clone https://github.com/PaddlePaddle/FastDeploy.git
 | ||
| cd examples/vision//retinaface/python/
 | ||
| 
 | ||
| #下载retinaface模型文件和测试图片
 | ||
| wget https://bj.bcebos.com/paddlehub/fastdeploy/Pytorch_RetinaFace_mobile0.25-640-640.onnx
 | ||
| wget https://raw.githubusercontent.com/DefTruth/lite.ai.toolkit/main/examples/lite/resources/test_lite_face_detector_3.jpg
 | ||
| 
 | ||
| # CPU推理
 | ||
| python infer.py --model Pytorch_RetinaFace_mobile0.25-640-640.onnx --image test_lite_face_detector_3.jpg --device cpu
 | ||
| # GPU推理
 | ||
| python infer.py --model Pytorch_RetinaFace_mobile0.25-640-640.onnx --image test_lite_face_detector_3.jpg --device gpu
 | ||
| # GPU上使用TensorRT推理
 | ||
| python infer.py --model Pytorch_RetinaFace_mobile0.25-640-640.onnx --image test_lite_face_detector_3.jpg --device gpu --use_trt True
 | ||
| ```
 | ||
| 
 | ||
| 运行完成可视化结果如下图所示
 | ||

 | ||
| 
 | ||
| ## RetinaFace Python接口
 | ||
| 
 | ||
| ```python
 | ||
| fastdeploy.vision.facedet.RetinaFace(model_file, params_file=None, runtime_option=None, model_format=ModelFormat.ONNX)
 | ||
| ```
 | ||
| 
 | ||
| RetinaFace模型加载和初始化,其中model_file为导出的ONNX模型格式
 | ||
| 
 | ||
| **参数**
 | ||
| 
 | ||
| > * **model_file**(str): 模型文件路径
 | ||
| > * **params_file**(str): 参数文件路径,当模型格式为ONNX格式时,此参数无需设定
 | ||
| > * **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ONNX
 | ||
| 
 | ||
| ### predict函数
 | ||
| 
 | ||
| > ```python
 | ||
| > RetinaFace.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
 | ||
| > > * **conf_threshold**(float): 检测框置信度过滤阈值
 | ||
| > > * **nms_iou_threshold**(float): NMS处理过程中iou阈值
 | ||
| 
 | ||
| > **返回**
 | ||
| >
 | ||
| > > 返回`fastdeploy.vision.FaceDetectionResult`结构体,结构体说明参考文档[视觉模型预测结果](../../../../../docs/api/vision_results/)
 | ||
| 
 | ||
| ### 类成员属性
 | ||
| #### 预处理参数
 | ||
| 用户可按照自己的实际需求,修改下列预处理参数,从而影响最终的推理和部署效果
 | ||
| 
 | ||
| > > * **size**(list[int]): 通过此参数修改预处理过程中resize的大小,包含两个整型元素,表示[width, height], 默认值为[640, 640]
 | ||
| > > * **variance**(list[float]): 通过此参数可以指定retinaface中的方差variance值,默认是[0.1,0.2], 一般不用修改.
 | ||
| > > * **min_sizes**(list[list[int]]): retinaface中的anchor的宽高设置,默认是 {{16, 32}, {64, 128}, {256, 512}},分别和步长8、16和32对应
 | ||
| > > * **downsample_strides**(list[int]): 通过此参数可以修改生成anchor的特征图的下采样倍数, 包含三个整型元素, 分别表示默认的生成anchor的下采样倍数, 默认值为[8, 16, 32]
 | ||
| > > * **landmarks_per_face**(int): 指定当前模型检测的人脸所带的关键点个数,默认为5.
