# PaddleSeg C++部署示例
|
||
|
||
本目录下提供`infer.cc`快速完成PP-LiteSeg在CPU/GPU，以及GPU上通过Paddle-TensorRT加速部署的示例。
|
||
|
||
## 部署环境准备
|
||
|
||
在部署前，需确认软硬件环境，同时下载预编译部署库，参考文档[FastDeploy预编译库安装](https://github.com/PaddlePaddle/FastDeploy/blob/develop/docs/cn/build_and_install#FastDeploy预编译库安装)
|
||
|
||
>> **注意** 如你部署的为**PP-Matting**、**PP-HumanMatting**以及**ModNet**请参考[Matting模型部署](../../../ppmatting)
|
||
|
||
以Linux上推理为例，在本目录执行如下命令即可完成编译测试，支持此模型需保证FastDeploy版本1.0.0以上(x.x.x>=1.0.0)
|
||
|
||
```bash
|
||
#下载部署示例代码
|
||
cd path/to/paddleseg/cpp-gpu/cpp
|
||
|
||
mkdir build
|
||
cd build
|
||
# 下载FastDeploy预编译库，用户可在上文提到的`FastDeploy预编译库`中自行选择合适的版本使用
|
||
wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
|
||
tar xvf fastdeploy-linux-x64-x.x.x.tgz
|
||
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
|
||
make -j
|
||
|
||
# 下载PP-LiteSeg模型文件和测试图片
|
||
wget https://bj.bcebos.com/paddlehub/fastdeploy/PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer.tgz
|
||
tar -xvf PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer.tgz
|
||
wget https://paddleseg.bj.bcebos.com/dygraph/demo/cityscapes_demo.png
|
||
|
||
|
||
# CPU推理
|
||
./infer_demo PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer cityscapes_demo.png 0
|
||
# GPU推理
|
||
./infer_demo PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer cityscapes_demo.png 1
|
||
# GPU上Paddle-TensorRT推理
|
||
./infer_demo PP_LiteSeg_B_STDC2_cityscapes_without_argmax_infer cityscapes_demo.png 2
|
||
```
|
||
|
||
运行完成可视化结果如下图所示
