CuDNN版本不匹配

Question

我非常接近使用keras/tensorflow python库来配置启用了gpu的环境。当我尝试训练我的模型时，我得到了一条很长的错误消息：

CuDNN library major and minor version needs to match or have higher minor version in case of CuDNN 7.0 or later version. If using a binary install, upgrade your CuDNN library.  If building from sources, make sure the library loaded at runtime is compatible with the version specified during compile configuration.

我看过几篇类似的堆栈溢出帖子，似乎我需要调整CuDNN版本或tensorflow-gpu版本。我从Nvidia的网站上下载了正确版本的CuDNN，但它似乎没有任何作用。我还发现了几篇关于更改tensorflow-gpu版本的帖子，但我应该下载哪个版本以及如何下载。我使用的是WIndows 10。

您好，这个powershell脚本应该可以更新您的驱动程序。
