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>

    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，一旦关闭终端窗口，并在新终端中键入 nvcc -V，它再次显示未安装

【解决方案1】：

对我有用的一件事是，我没有使用 'export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/local/cuda/lib64" ' 'export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:~/cuda/lib64" ' 和有效。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。

【讨论】：

尝试在您的 .bashrc 文件中添加这两个导出命令。这样您就不必每次都这样做

【解决方案2】：

您需要安装 cuDNN v6.0 库。

【解决方案3】：

其实我在按照官方安装文档安装tensorflow-gpu的时候遇到了这个问题。我通过更改 tensorflow-gpu 的版本解决了这个问题。

pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.3.0-cp36-cp36m-linux_x86_64.whl

我将数字 1.3.0 改为 1.2.0 ，它可以工作。新的安装命令如下：

pip install --ignore-installed --upgrade https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow_gpu-1.2.0-cp36-cp36m-linux_x86_64.whl
