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

Question

我在 Windows 10 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。这在开发机器和其他 Windows 10 机器上运行良好。 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

谁能建议我如何解决这个问题？

谢谢

我遇到了同样的问题。

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。

希望对你有帮助！
