# SCRFD 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/rknpu2.md)
本目录下提供`infer.py`快速完成SCRFD在RKNPU上部署的示例。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 FastDeploy/examples/vision/facedet/scrfd/rknpu2/python
# 下载图片
wget https://raw.githubusercontent.com/DefTruth/lite.ai.toolkit/main/examples/lite/resources/test_lite_face_detector_3.jpg
# 推理
python3 infer.py --model_file ./scrfd_500m_bnkps_shape640x640_rk3588.rknn \
--image test_lite_face_detector_3.jpg
```
## 注意事项
RKNPU上对模型的输入要求是使用NHWC格式且图片归一化操作会在转RKNN模型时内嵌到模型中因此我们在使用FastDeploy部署时
需要先调用DisableNormalizePermute(C++)或`disable_normalize_permute(Python),在预处理阶段禁用归一化以及数据格式的转换。
