ImportError：libcudnn.so.6：无法打开共享对象文件：没有这样的文件或目录Tensorflow

Question

我无法让它工作！试了快两天了。安装了 Cuda8 和 CuDnn 6 - 没用。在此处添加了ImportError: libcudnn when running a TensorFlow program 中编写的解决方案。 我得到的错误 -

Traceback（最近一次调用最后一次）：

Failed to load the native TensorFlow runtime.

我是新手。任何帮助将不胜感激。如果您需要更多信息，我很乐意提供。

Answer 1

安装cuda 和cudnn 后，确保它们位于正确的目录中。 安装cudnn 6 后运行以下命令。 Tensorflow 只检查cuda 目录上的所需文件。因此，我们将所需文件从cudnn 复制或链接到该目录。

mkdir /usr/lib/x86_64-linux-gnu/include/ && \
  ln -s /usr/lib/x86_64-linux-gnu/include/cudnn.h /usr/lib/x86_64-linux-gnu/include/cudnn.h && \
  ln -s /usr/include/cudnn.h /usr/local/cuda/include/cudnn.h && \
  ln -s /usr/lib/x86_64-linux-gnu/libcudnn.so /usr/local/cuda/lib64/libcudnn.so && 
  ln -s /usr/lib/x86_64-linux-gnu/libcudnn.so.6 /usr/local/cuda/lib64/libcudnn.so.6

因此，如果您仍然遇到该错误，请确保按照步骤here。
