无法在 Windows 2012 R2 服务器上加载 DLL 'tensorflow'

Question

我在Windows 10上的Visual Studio中使用 ML.Net Model Builer创建了一个图像分类器。 它已编译到控制台应用程序中。 这在开发计算机和其他 Windows 10 计算机上运行良好。 我需要将其部署到 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
on has been thrown by the target of an invocation. ---> System.Reflection.Target

任何人都可以建议我如何解决这个问题吗？

谢谢

我陷入了同样的问题。

解决方案是添加功能"桌面体验"，默认情况下不包含在W2012安装中。

我希望这对您的情况有所帮助！
