问题描述

I have created an image classifier using ML.Net Model Builer in Visual Studio on Windows 10. It has been compiled in to a Console application.我在 Windows 10 上的 Visual Studio 中使用 ML.Net 模型构建器创建了一个图像分类器。它已被编译到控制台应用程序中。 This runs fine on the development machine and other Windows 10 machines.这在开发机器和其他 Windows 10 机器上运行良好。 I need to deploy it to a Windows 2012 R2 server but when I start the application I get this error message:我需要将它部署到 Windows 2012 R2 服务器，但是当我启动应用程序时，我收到以下错误消息：

System.Reflection.TargetInvocationException: Exception has been thrown by the ta
rget of an invocation. ---> System.Reflection.TargetInvocationException: Excepti

Can anyone suggest how I can fix this?谁能建议我如何解决这个问题？

Thanks谢谢

I was stuck in the same issue.我陷入了同样的问题。

The solution was to Add Feature "Desktop Experience", which is not by default included in W2012 installation.解决方案是添加功能“桌面体验”，W2012 安装中默认不包含该功能。

I hope that helps in your case!我希望这对您的情况有所帮助！
