# PaddleSeg 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)
【注意】如你部署的为**PP-Matting**、**PP-HumanMatting**以及**ModNet**请参考[Matting模型部署](../../../../matting/)
本目录下提供`infer.py`快速完成PPHumanseg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/segmentation/paddleseg/python
# 下载图片
wget https://paddleseg.bj.bcebos.com/dygraph/pp_humanseg_v2/images.zip
unzip images.zip
# 推理
python3 infer.py --model_file ./Portrait_PP_HumanSegV2_Lite_256x144_infer/Portrait_PP_HumanSegV2_Lite_256x144_infer_rk3588.rknn \
--config_file ./Portrait_PP_HumanSegV2_Lite_256x144_infer/deploy.yaml \
--image images/portrait_heng.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DisableNormalizeAndPermute(C++)或`disable_normalize_and_permute(Python),在预处理阶段禁用归一化以及数据格式的转换。
