[日常踩坑]ubuntu 14.04 安装tensorflow -gpu 提示 Traceback (most recent call last):

第一次安装tensorflow,本以为很顺利，结果进入python环境import tensorflow as tf 一直出错，配置版本CUDA 8+CUDNN6+tensorflow1.3/8/9(没错各个版本都试过了）

错误显示如下：

解决方案：配置cudnn环境变量 ;

• cuDnn 6.x 安装
• tar -xzvf cudnn-8.0-linux-x64-v6.0.tgz
  sudo cp cuda/include/cudnn.h /usr/local/cuda-8.0/include
  sudo cp cuda/lib64/libcudnn* /usr/local/cuda-8.0/lib64
  sudo chmod a+r /usr/local/cuda/include/cudnn.h /usr/local/cuda-8.0/lib64/libcudnn*
  sudo ln -sf libcudnn.so.6.1.10 libcudnn.so.6  
  sudo ln -sf libcudnn.so.6 libcudnn.so  
  sudo ldconfig  
• 配置环境变量（）

• 在 ~/.bashrc 里再设置一下cuda的环境变量：

• export PATH=/usr/local/cuda/bin${PATH:+:${PATH}}
  export LD_LIBRARY_PATH=/usr/local/cuda/lib64${LD_LIBRARY_PATH:+:${LD_LIBRARY_PATH}}
  export CUDA_HOME=/usr/local/cuda export LD_LIBR同时 source ~/.bashrc 让其生效。

测试版本为tensorflow 1.3.0版本 ，修改后一切正常。
