安装C++接口的onnx-runtime

安装依赖项：

安装CMake：可以通过包管理器（如apt、yum等）安装CMake。

安装C++编译器：确保系统中已安装C++编译器，如GCC或Clang。

下载源文件

克隆ONNX Runtime的GitHub仓库，指定版本是为了适配python3.8：

git clone --branch v1.5.2 --recursive https://gitee.com/lee-zq/onnxruntime.git

构建ONNX Runtime

进入ONNX Runtime的源代码目录：
// 首先创建一个conda环境，因为./build.sh实际上调用的是./tools/cl_build/build.py

cd onnxruntime
conda create -n onnxruntime python=3.8
./build.sh --skip_tests --config Release --build_shared_lib --parallel

注意，若配合cuda使用，命令行末尾应添加

-cuda_home /usr/local/cuda-11.3 --cudnn_home /usr/local/cuda-11.3

注意，编译前，确保机器装有linux环境：

sudo apt-get install build-essential

这将使用所有可用的CPU核心进行编译。如果希望使用指定数量的核心，可以将$(nproc)替换为所需的核心数量。

安装ONNX Runtime

运行以下命令进行安装：

cd /build/Linux/Release
sudo make install

通过按照上述步骤，您应该能够在Linux上成功安装ONNX Runtime。请注意，安装过程中可能需要根据您的系统和需求进行适当的调整。
