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

Question

导入 Tensorflow 时出现以下错误。

    >>> import tensorflow
Traceback (most recent call last):
  File "/home/jarvis/anaconda3/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow.py", line 41, in <module>
    from tensorflow.python.pywrap_tensorflow_internal import *
  File "/home/jarvis/anaconda3/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 28, in <module>
    _pywrap_tensorflow_internal = swig_import_helper()
  File "/home/jarvis/anaconda3/lib/python3.6/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 24, in swig_import_helper
    _mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
  File "/home/jarvis/anaconda3/lib/python3.6/imp.py", line 242, in load_module
    return load_dynamic(name, filename, file)
  File "/home/jarvis/anaconda3/lib/python3.6/imp.py", line 342, in load_dynamic
    return _load(spec)
ImportError: libcudnn.so.6: cannot open shared object file: No such file or directory

During handling of the above exception, another exception occurred:

Failed to load the native TensorFlow runtime.

我也添加了路径变量

$ export PATH=/usr/local/cuda-8.0/bin${PATH:+:${PATH}}
$ export LD_LIBRARY_PATH=/usr/local/cuda-8.0/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}

然后系统检测到nvcc。
但是，只要关闭终端窗口并在新终端中键入 nvcc -V ，它就会再次显示未安装

对我有用的一件事是，我没有使用 'export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64"'，而是使用了 'export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:~/cuda/lib64"'，它确实有效。每次计算机启动时我都必须这样做。不知道 cuda 在我的主文件夹中做什么，也不知道为什么我每次都需要这样做。
