python中使用tensorflow的問題描述
在python3中，導入tensorflow時遇到了以下問題：
>>> import tensorflow as tf
Traceback (most recent call last):
File "/usr/local/lib/python3.5/dist-packages/tensorflow/python/pywrap_tensorflow.py", line 41, in <module>

File "/usr/lib/python3.5/imp.py", line 342, in load_dynamic
return _load(spec)
ImportError: libcusolver.so.8.0: cannot open shared object file: No such file or directory
During handling of the above exception, another exception occurred:

考慮到版本375有這個BUG：從睡眠模式喚醒電腦後，沿著窗口邊界有奇怪的東西，我使用的Nvidia驅動程序是381.09測試版。
而且，我已經安裝了CUDA 8.0和cuDNN-v6.0：
rharish@rharish-GL552VW:~$ cd /usr/local
rharish@rharish-GL552VW:/usr/local$ ls
bin cuda etc include man share
computecpp cuda-8.0 games lib sbin src
此外，libcusolver.so.8.0也存在於/usr/local/cuda/lib64/中：
libcusolver.so.8.0 in ‘ls’ output
我已經卸載並重新安裝了CUDA，cuDNN，還從源代編譯安裝過tensorflow。但是，隻要將Nvidia驅動程序更新為381.09版本，這個問題就會發生。需要怎麽解決這個問題？
最佳解決辦法
經驗證有效的解決方案：
重新安裝nvidia-381，CUDA-8.0(使用runfile)和cuDNN 6.0，然後在.bashrc文件中添加了以下內容：
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/cuda/lib64/
另外一種解決思路
不需要重新安裝上述的各種軟件包，隻需要安裝nvidia-cuda-dev:
sudo apt install nvidia-cuda-dev
然後安裝cuDNN(可以從這裏下載:https://developer.nvidia.com/cudnn)，最後相應地設置LD_LIBRARY_PATH
指向cuda/lib64即可。
