FastDeploy 安装教程

3. FastDeploy 部署(CSharp)

FastDeploy C# SDK的接口实现，为用户需要C# API的场景提供解决方案。

3.1 FastDeploy 源码编译

1. CMAKE_CONFIGURATION_TYPES 属性设置为Release

2. 请不要勾选WITH_GPU和ENABLE_TRT_BACKEND

3. 开启

   ENABLE_ORT_BACKEND=ON
   ENABLE_PADDLE_BACKEND=ON 
   ENABLE_OPENVINO_BACKEND=ON 
   ENABLE_VISION=ON 
   ENABLE_TEXT=ON 
   WITH_CAPI=ON 
   WITH_CSHARPAPI=ON 
   

4. 指定CMAKE_INSTALL_PREFIX 安装路径

5. 生成fastdeploy.sln解决方案文件选择Release版本，生成编译，点击"INSTALL"->右键点击"生成"将编译好的SDK安装到先前指定的目录步骤⑤。

   

3.2 创建CSharp项目

1. 在项目引用中添加–>fastdeploy_csharp；

2. nuget 包添加OpenCvSharp、OpenCvSharp.Extensions等包

3. 在debug\relese项目文件夹中添加Fastdeploy的动态链接库；

fastdeploy_init.bat install %cd% D:\workSpace\Paddle\deploy\FastDeplyCsharp\FastDeplyCsharp\bin\x64\Debug
