python - tensorflow-gpu 1.8.0 ImportError : libcudnn. so.7:无法打开共享对象文件:没有这样的文件或目录

Question

我刚刚安装

Ubuntu 18.04

NVIDIA GPU 驱动程序 390

CUDA工具包版本9.0(包含所有补丁)

CUDNN 7.0.5

点击了此链接 https://github.com/markjay4k/Install-Tensorflow-on-Ubuntu-17.10-/blob/master/Tensorflow%20Install%20instructions.ipynb

并代替conda进行tensorflow安装我使用过 Virtualenv

安装后，我无法在python中导入tensorflow模块由于这个错误

Python 2.7.15rc1 (default, Apr 15 2018, 21:51:34) 
[GCC 7.3.0] on linux2

>>> import tensorflow as tf
Traceback (most recent call last):

    raise ImportError(msg)
ImportError: Traceback (most recent call last):

    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
ImportError: libcudnn.so.7: cannot open shared object file: No such file or directory

但我认为我正确地将它们放在正确的位置，如下所示

$ cd /usr/local/cuda/lib64
:/usr/local/cuda/lib64$ ls -l libcudnn*
-rwxr-xr-x 1 root root 287624224 May 15 19:01 libcudnn.so
-rwxr-xr-x 1 root root 287624224 May 15 19:01 libcudnn.so.7
-rwxr-xr-x 1 root root 287624224 May 15 19:01 libcudnn.so.7.0.5
-rw-r--r-- 1 root root 280805558 May 15 19:02 libcudnn_static.a

所以现在我想知道为什么会发生这种情况

解决方法

sudo apt install nvidia-cuda-toolkit

不知道为什么官方网站上没有这方面的提示
