# AdaFace Python部署示例
|
||
本目录下提供infer_xxx.py快速完成AdaFace模型在CPU/GPU，以及GPU上通过TensorRT加速部署的示例。
|
||
|
||
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)
|
||
|
||
以AdaFace为例子, 提供`infer.py`快速完成AdaFace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/faceid/adaface/python/
|
||
|
||
#下载AdaFace模型文件和测试图片
|
||
#下载测试图片
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/rknpu2/face_demo.zip
|
||
unzip face_demo.zip
|
||
|
||
# 如果为Paddle模型，运行以下代码
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/mobilefacenet_adaface.tgz
|
||
tar zxvf mobilefacenet_adaface.tgz -C ./
|
||
|
||
# CPU推理
|
||
python infer.py --model mobilefacenet_adaface/mobilefacenet_adaface.pdmodel \
|
||
--params_file mobilefacenet_adaface/mobilefacenet_adaface.pdiparams \
|

|
||
# GPU推理
|
||
python infer.py --model mobilefacenet_adaface/mobilefacenet_adaface.pdmodel \
|

--params_file mobilefacenet_adaface/mobilefacenet_adaface.pdiparams \
|
||
--face face_0.jpg \
|
||
--face_positive face_1.jpg \
|
||
--face_negative face_2.jpg \
|
||

|
||
# GPU上使用TensorRT推理
|
||
python infer.py --model mobilefacenet_adaface/mobilefacenet_adaface.pdmodel \
|
||
--params_file mobilefacenet_adaface/mobilefacenet_adaface.pdiparams \
|
||
--face face_0.jpg \
|
||
--face_positive face_1.jpg \
|
||
--face_negative face_2.jpg \
|
||
--device gpu \
|
||
--use_trt True
|

# 昆仑芯XPU推理
|
||
python infer.py --model mobilefacenet_adaface/mobilefacenet_adaface.pdmodel \
|
||
--params_file mobilefacenet_adaface/mobilefacenet_adaface.pdiparams \
|

## AdaFace Python接口
|
||
|
||
```python
|
||
fastdeploy.vision.faceid.AdaFace(model_file, params_file=None, runtime_option=None, model_format=ModelFormat.PADDLE)
|
||
```
|
||
|
||
AdaFace模型加载和初始化，其中model_file为导出的ONNX模型格式或PADDLE静态图格式
|
||
|
||
**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PADDLE
|
||
|
||
### predict函数
|
||
|
||
> ```python
|
||
> AdaFace.predict(image_data)
|
||
> ```
|
||
>
|
||
> 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.FaceRecognitionResult`结构体，结构体说明参考文档[视觉模型预测结果](../../../../../docs/api/vision_results/)
