.net - CNTK.CPUOnly在Docker中[Windows]

Question

我想使用 CNTK.CPUOnly 实现简单的.net 4.7应用程序
然后将其推送到Docker [Windows]。

脚步:

在Visual Studio 2017中创建新的.net 4.7控制台应用程序

打开NuGet管理器并添加CNTK.CPUOnly包(带有依赖项)

编写简单的应用程序:

using System;
using System.IO;
namespace cntk_docker
{
    class Program
    {
        static void Main(string[] args)
        {
            var files = Directory.GetFiles(AppDomain.CurrentDomain.BaseDirectory);
            foreach (var file in files)
            {
                Console.WriteLine(file);
            }   
            var device = CNTK.DeviceDescriptor.CPUDevice;
            Console.WriteLine(device);
            Console.Read();
        }
    }
}

然后我创建了 Dockerfile :

FROM microsoft/dotnet-framework:4.7
WORKDIR /app
COPY bin/x64/Release .
ENTRYPOINT ["cntk_docker.exe"] 

当我尝试在Docker中运行应用程序时出现异常:

但是它在我的本地计算机和任何其他带有.net4.7的win10计算机中都可以正常工作。我做错了什么？

Answer 1

看起来像CNTK.CPUOnly不能没有以下功能:

Microsoft Visual C++ 2013可再发行(x86)

Microsoft Visual C++ 2013可再发行(x64)

更新Docker文件后，一切正常
