从源文件NotFoundError生成onnxruntime时出现问题

Question

我试图从源代码构建onnxruntime，但遇到了以下问题

执行后

git clone https://github.com/microsoft/onnxruntime.git
cd onnxruntime
./build.bat

我遇到了以下错误

2020-08-31 11:14:05,414 Build [DEBUG] - Defaulting to running update, build [and test for native builds].
2020-08-31 11:14:05,414 Build [INFO] - Build started

    hp, ht, pid, tid = _winapi.CreateProcess(executable, args,
FileNotFoundError: [WinError 2] The system cannot find the file specified

我试图更具体地介绍VisualStudio版本，但我不确定这是否是问题所在。添加标记--msvc 16.7.2会产生相同的错误。这似乎是一条相当一般的错误消息，可能不是特定于onnxruntime构建的

使用管理权限没有帮助

这个问题的原因是什么？我需要做什么来解决它

Answer 1

您应该使用—recursive下载所有相关子模块：

git clone —recursive https://github.com/microsoft/onnxruntime.git

如果您想为visual studio构建它，您应该为visual studio 2017打开“VS 2017开发者命令提示符”，或为visual studio 2019打开“VS 2019开发者命令提示符”。 如果使用visual studio 2019，则应将此命令添加到命令 cmake_generator "Visual Studio 16 2019"的末尾，如：

cd onnxruntime    
build.bat  cmake_generator "Visual Studio 16 2019"

Answer 2

尝试使用—recursive下载所有相关子模块。比如： git clone —recursive https://github.com/microsoft/onnxruntime.git cd onnxruntime ./build.bat
