使用Anaconda搭建TensorFlow-GPU环境
前言：
对于深度学习来说，各种框架torch,caffe,keras,mxnet,tensorflow,pandapanda环境要求各一，如果我们在一台服务器上部署了较多的这样的框架，那么各种莫名的冲突
会一直伴随着你，吃过很多次亏之后，慢慢的接触了Anaconda，真的是很爽的一个功能，来管理环境配置。我们进行tensorflow安装的时候，还是使用Anaconda，鉴于国内墙太高
，我们使用了Tsinghua的镜像文件，清华大学的Anaconda介绍地址见：https://mirror.tuna.tsinghua.edu.cn/help/anaconda/
这里记录下linux的安装方式：
所使用的系统: ubuntu16.10
安装步骤
1： 先登录到这个页面：https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/
2. 下载： wget -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda2-2.4.1-Linux-x86_64.sh
3. 运行： bash Anaconda2-2.i.1-Linux-x86_64.sh [中间会有几个询问，全部设置yes或者y]
4. 设置镜像仓库：
TUNA 还提供了 Anaconda 仓库的镜像，运行以下命令:
conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
conda config --set show_channel_urls yes
即可添加 Anaconda Python 免费仓库。
运行 conda install numpy 测试一下吧。
5. 安装tensorflow:
5.1 查询conda下的tensorflow可以利用的镜像：
anaconda search -t conda tensorflow大概会出现这些信息：
gxjun@gxjun:~$ anaconda search -t conda tensorflow
Using Anaconda API: https://api.anaconda.org
Run 'anaconda show <USER/PACKAGE>' to get more details:

Found 36 packages我们选择其中的一个进行安装之前，先查询这个分支的URL路径：
gxjun@gxjun:~$ anaconda show nehaljwani/tensorflow-gpu
Using Anaconda API: https://api.anaconda.org
Name: tensorflow-gpu
Summary: TensorFlow is a machine learning library
Access: public
Package Types: conda
Versions:
+ 1.1.0
To install this package with conda run:
conda install --channel https://conda.anaconda.org/nehaljwani tensorflow-gpu5.2 安装
conda install --channel https://conda.anaconda.org/nehaljwani tensorflow-gpu5.3 检测是否安装成功：
在控制端输入：
python -> 进入python编辑环境
import tensorflow as tf 如果没有报错，则说明幸运的安装成功了~
对于失败的情况，我这里给出最容易出现的：
>>> import tensorflow as tf

ImportError: libcusolver.so.7.5: cannot open shared object file: No such file or directory这种问题，是说我们没有找到这个动态库，或者干脆就没有这个动态库.
解决方法：
先问是不是： 输入这条命令查查看有没有： locate libcusolver.so
gxjun@gxjun:~$ locate libcusolver.so
/usr/lib/x86_64-linux-gnu/libcusolver.so
/usr/lib/x86_64-linux-gnu/libcusolver.so.8.0
/usr/lib/x86_64-linux-gnu/libcusolver.so.8.0.44
/usr/lib/x86_64-linux-gnu/stubs/libcusolver.so
/usr/local/cuda-8.0/doc/man/man7/libcusolver.so.7
/usr/local/cuda-8.0/targets/x86_64-linux/lib/libcusolver.so
/usr/local/cuda-8.0/targets/x86_64-linux/lib/libcusolver.so.8.0
/usr/local/cuda-8.0/targets/x86_64-linux/lib/libcusolver.so.8.0.61
/usr/local/cuda-8.0/targets/x86_64-linux/lib/stubs/libcusolver.so
/usr/share/man/man7/libcusolver.so.7.gz我们发现我们只有libcusolver.so.8.0，并没有我们要找的libcusolver.so.7.5,看了一下官方的文档：
给出的建议是： 可以使用.8.0来替代.7.5，我们命名一个.8.0的软连接为.7.5
我们先到/usr/lib/cuda/lib64 下：
ln -s libcusolver.so.8.0 libcusolver.so.7.5然后在.bashrc系统环境下配置一下这个路径：
export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:/usr/lib/cuda/lib64"
export CUDA_HOME=/usr/local/cuda然后在测试：
gxjun@gxjun:~$ python
