# PaddleClas C++部署示例
|
|
|
|
|
|
|
|
|
|
|
|
本目录下提供`infer.cc`快速完成ResNet50_vd模型在SOPHGO BM1684x板子上加速部署的示例。
|
|
|
|
|
|
|
|
|
|
|
|
## 1. 部署环境准备
|
|
|
|
|
|
在部署前，需自行编译基于SOPHGO硬件的预测库，参考文档[SOPHGO硬件部署环境](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#算能硬件部署环境)
|
|
|
|
|
|
|
|
|
|
|
|
## 2. 生成基本目录文件
|
|
|
|
|
|
|
|
|
|
|
|
该例程由以下几个部分组成
|
|
|
|
|
|
```text
|
|
|
|
|
|
.
|
|
|
|
|
|
├── CMakeLists.txt
|
|
|
|
|
|
├── build # 编译文件夹
|
|
|
|
|
|
├── image # 存放图片的文件夹
|
|
|
|
|
|
├── infer.cc
|
|
|
|
|
|
├── preprocess_config.yaml #示例前处理配置文件
|
|
|
|
|
|
└── model # 存放模型文件的文件夹
|
|
|
|
|
|
```
|
|
|
|
|
|
## 3. 部署实例
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### 3.1 编译并拷贝SDK到thirdpartys文件夹
|
|
|
|
|
|
|
|
|
|
|
|
请参考[SOPHGO部署库编译](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install/sophgo.md)仓库编译SDK，编译完成后，将在build目录下生成fastdeploy-x.x.x目录.
|
|
|
|
|
|
|
|
|
|
|
|
### 3.2 拷贝模型文件，以及配置文件至model文件夹
|
|
|
|
|
|
将Paddle模型转换为SOPHGO bmodel模型，转换步骤参考[文档](../README.md)
|
|
|
|
|
|
将转换后的SOPHGO bmodel模型文件拷贝至model中
|
|
|
|
|
|
将前处理配置文件也拷贝到model中
|
|
|
|
|
|
```bash
|
|
|
|
|
|
cp preprocess_config.yaml ./model
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
### 3.3 准备测试图片至image文件夹
|
|
|
|
|
|
```bash
|
|
|
|
|
|
wget https://gitee.com/paddlepaddle/PaddleClas/raw/release/2.4/deploy/images/ImageNet/ILSVRC2012_val_00000010.jpeg
|
|
|
|
|
|
cp ILSVRC2012_val_00000010.jpeg ./images
|
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
|
|
