下载地址：Releases · microsoft/onnxruntime (github.com)
在下载地址找到对应版本，历史版本在Assets点开折叠后可以看到，可下载内容如下，如果需要支持GPU需要下载对应版本。
也可以通过指定版本的地址直接定位到想要的版本，例如1.8.0
https://github.com/microsoft/onnxruntime/releases/tag/v1.8.0
因为onnxruntime官方不支持windows编译（编译需要的Nvidia NCCL不支持widows），所以使用release包时需要使用比较严格对应的CUDA和cudnn，参考安装说明。但实际测试发现也并非严格对应，比如1.10.0可以用1.8.0的环境，但不能用1.6.0的环境。
Please reference table below for official GPU packages dependencies for the ONNX Runtime inferencing package. Note that ONNX Runtime Training is aligned with PyTorch CUDA versions; refer to the Training tab on https://onnxruntime.ai/ for supported versions.
Note: Because of CUDA Minor Version Compatibility, Onnx Runtime built with CUDA 11.4 should be compatible with any CUDA 11.x version. Please reference Nvidia CUDA Minor Version Compatibility.

For older versions, please reference the readme and build pages on the release branch.
以CUDA11.0.3和cudnn8.0.2.39下载环境安装，CUDA只安装runtime和development，cudnn解压放到cuda安装目录即可。
工程属性
C/C++ -> Additional Include Directories添加：
D:\libs\onnxruntime-win-x64-gpu-1.10.0\include
Linker -> Additional Library Directories添加：
D:\libs\onnxruntime-win-x64-gpu-1.10.0\lib
Linker -> Input -> Additional
onnxruntime.lib
使用时
#include <onnxruntime_cxx_api.h>如果cuda/cudnn环境与onnxruntime不适配，在session.run()时会报错，例如：
Unhandled exception at 0x00007FF84C9D313C (cudnn64_8.dll) in onnx.exe: Fatal program exit requested.
