Question

我在 macOS Sierra 10.12.2

VisualStudio Mac Preview 2 上使用NuGet

当我尝试安装Microsoft CNTK软件包时：

Microsoft.Research.CNTK.CpuEval-acml 1.5.0

Microsoft.Research.CNTK.CpuEval-mkl 1.7.2

我收到了一些错误

Done Building Project "/Users/loretoparisi/Projects/CNTKDemo/CNTKDemo/CNTKDemo.csproj" (restore target(s)) -- FAILED.



Build FAILED.

[UPDATE] 使用.NET控制台项目，可以通过NuGet预安装软件包CNTK.CPUOnly 2.0.0-beta8。顺便说一下，运行一个使用CNTK包的基本示例代码，如[this] [1]，改编自CNTK的简单示例Eval示例[here] [2]会导致异常：

这是由于类型初始值设定项SWIGExceptionHelper：

System.TypeInitializationException: The type initializer for 'CNTK.CNTKLibPINVOKE' threw an exception. ---> System.TypeInitializationException: The type initializer for 'SWIGExceptionHelper' threw an exception. ---> System.DllNotFoundException: CNTKLibraryCSBinding

Answer 1

CNTK Eval Nuget Package目前需要.NET 4.5。我不知道你使用的MonoFramework 4.8是否支持它。另外，C＃Eval需要一些为Intel / AMD X64平台构建的本机dll，我不确定它们是否可以直接在你的MAC机器上运行？另一个问题：你有什么特别的理由使用Microsoft.Research.CNTK.CpuEval-acml 1.5.0吗？它被淘汰了，我们目前使用英特尔MKL而不是ACML，最新版本是微软CNTK Eval CPUOnly-mkl NuGet 2.0.0-beta7。请启用＆＃34;包含预发布＆＃34;搜索Nuget包时的选项，否则只能找到Microsoft CNTK Eval CPUOnly-mkl NuGet 1.7.2。

NuGet上的Microsoft CNTK和Mac上的VisualStudio
