Question

似乎CuDNN安装程序正在寻找错误版本的CUDA。我究竟做错了什么？完整的故事：

Ubuntu 16.04

已安装两个版本的CUDA，分别为9.0和9.1。 / usr / lib / cuda链接到9.1安装，并且LD_LIBRARY_PATH似乎指向该目录：

// Use this or injected parameter
var loader = ServiceLocator.Current.GetInstance<IContentLoader>();

// Remove all children or not
var cascade = true;

ContentReference entryPoint = ...where you want to start

// Get all indexable languages from Find
Languages languages = SearchClient.Instance.Settings.Languages;

// Remove all current instances of all languages below the selected content node
//languages.ForEach(x => ContentIndexer.Instance.RemoveFromIndex(entryPoint, cascade.Checked, x.FieldSuffix));

foreach (var lang in languages)
{
    if (cascade)
    {
        var descendents = loader.GetDescendents(entryPoint);

        foreach (ContentReference descendent in descendents)
        {
            ContentIndexer.Instance.RemoveFromIndex(descendent, false, lang.FieldSuffix);
        }
    }

    // Try delete the entrypoint
    var entryTest = loader.Get<IContent>(entryPoint, new CultureInfo(lang.FieldSuffix));
    if (entryTest != null)
    {
        var delRes = ContentIndexer.Instance.Delete(entryTest);
    }
}

现在我确实已经安装了CuDNN 7.0，想将其替换为7.1版。（这可能是一个不明智的决定，但是，我已经开始这样做了！）

下载了用于CuDNN 7.1.3的debian安装程序，以与CUDA 9.1一起使用。试图通过以下方式安装它：

$ echo $LD_LIBRARY_PATH
/usr/local/cuda/lib64:/usr/local/lib
$ ls -l /usr/local
lrwxrwxrwx  1 root root     8 jan 22  2018 cuda -> cuda-9.1
drwxr-xr-x 15 root root  4096 dec  1  2017 cuda-9.0
drwxr-xr-x 15 root root  4096 jan 22  2018 cuda-9.1

如您所见，安装程序在库文件之后查找cuda-9.0目录。（为什么？）文件存在，但它不是符号链接：

$ sudo dpkg -i libcudnn7_7.1.3.16-1+cuda9.1_amd64.deb
(Reading database ... 261910 files and directories currently installed.)
Preparing to unpack libcudnn7_7.1.3.16-1+cuda9.1_amd64.deb ...

/sbin/ldconfig.real: /usr/local/cuda-9.0/targets/x86_64-linux/lib/libcudnn.so.7 is not a symbolic link

我也尝试删除libcudnn，但是在第一次重新安装后我这样做了，因此删除会引发相同类型的错误：

$ ls -l /usr/local/cuda-9.0/targets/x86_64-linux/lib/libcudnn.so
-rwxr-xr-x 1 root root 287624224 jan 16  2018 /usr/local/cuda-9.0/targets/x86_64-linux/lib/libcudnn.so

因此，更大的图景：我的目标是正确安装CuDNN 7.1。我该如何实现该目标？

我终于做到了！我进去并手动删除了.so文件：

$ sudo apt-get remove libcudnn7

然后使用dpkg进行安装，然后重新安装我的tensorflow-gpu，从而确认一切正常：

$ cd /usr/local/cuda-9.0/targets/x86_64-linux/lib/
$ sudo mv libcudnn.so bak_libcudnn.so
$ sudo mv libcudnn.so.7 bak_libcudnn.so.7
$ sudo mv libcudnn.so.7.0.5 bak_libcudnn.so.7.0.5
