我在 ML.net 的 MVC5 asp.net 中遇到此问题，如果有人在此之前遇到此问题，请提供帮助，谢谢。

我遇到了同样的问题，我疯了几天。

解决问题的方法如下：

1. 检查是否安装了 Visual Studio 2015、2017、2019 和 2022 的 VC vcredist_x64。您可以在这里找到它：https://learn.microsoft.com/en-us/cpp/windows/latest-supported-vc-redist?view=msvc-170
2. 检查Java Open JDK 11.2是否安装，BIN路径是否在路径环境表中。最后我从这里安装了microsoft-jdk-11.0.21-windows-x64：https://learn.microsoft.com/en-us/java/openjdk/download
3. 检查应用程序池是否以32位模式运行。如果是，只需在 IIS 管理器中禁用该选项即可。

祝你有美好的一天，米歇尔
