Ubuntu14.04下TensorFlow的安装及配置

在安装了cuda7.5和更新了cudnn版本之后，就可以进行TensorFlow的安装配置了，进入官方下载地址进行下载安装，tensorflow的github地址：https://github.com/tensorflow/tensorflow。

具体安装只需一条指令，

sudo pip install /home/lc/Downloads/tensorflow_gpu-1.2.0rc0-cp27-none-linux_x86_64.whl

更换你自己的路径与文件名

此时安装路径为

/usr/local/lib/python2.7/dist-packages/

这不是本文要介绍的重点，依然要针对我安装过程时出现的问题，进行相关的展开。

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/tensorflow/__init__.py", line 24, in <module>

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

File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 28, in <module>

File "/home/ubuntu/anaconda2/lib/python2.7/site-packages/tensorflow/python/pywrap_tensorflow_internal.py", line 24, in swig_import_helper
_mod = imp.load_module('_pywrap_tensorflow_internal', fp, pathname, description)
ImportError: libcusolver.so.8.0: cannot open shared object file: No such file or directory

当我Python命令行中输入语句

import tensorflow as tf

出现以上错误，查了很多别人的疑问解答，都是以改变环境变量为主，

sudo vim ~/.bashrc
export LD_LIBRARY_PATH=”$LD_LIBRARY_PATH:/usr/local/cuda/lib64”
export CUDA_HOME=/usr/local/cuda
source ~/.bashrc

但我这么做以后依然没有解决，

仔细分析，其实不光是环境变量路径的问题，TensorFlow现在的安装版本适配的应该是cuda8.0的，而我安装的是cuda7.5版本，所以需要降级版本安装，

sudo pip install --upgrade \ https://storage.googleapis.com/tensorflow/linux/gpu/tensorflow-0.10.0-cp27-none-linux_x86_64.whl[/code] 
可能有些人的电脑pip安装还会出现一些问题，在安装之前最好执行以下语句，

sudo apt-get install python-pip


这一条是针对的Python2版本，如果你是Python3（sudo apt-get install python3-pip  ）

安装之后，运行TensorFlow的运行检测，如果正常就说明万事大吉了。

我的是还遇到了下面的问题，

>>> import tensorflow as tf
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/local/Cellar/python/2.7.6/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/tensorflow/__init__.py", line 23, in <module>

from pbr.version import VersionInfo
ImportError: No module named pbr.version


针对这个问题，你只需要

sudo pip install pbr funcsigs


即可修复。

以上皆是我在安装时遇到的各种问题，通过搜索相关资料，最后都进行了有效的解决，希望能给你有用的参考。
