Anaconda+Tensorflow环境安装与配置

转载请注明出处:http://www.cnblogs.com/willnote/p/6746499.html

Anaconda安装

清华大学 TUNA 镜像源选择对应的操作系统与所需的Python版本下载Anaconda安装包。Windows环境下的安装包直接执行.exe文件进行安装即可,Ubuntu环境下在终端执行

$ bash Anaconda2-4.3.1-Linux-x86_64.sh   #Python 2.7版本

或者

$ bash Anaconda3-4.3.1-Linux-x86_64.sh  #Python 3.5 版本

在安装的过程中,会询问安装路径,按回车即可。之后会询问是否将Anaconda安装路径加入到环境变量(.bashrc)中,输入yes,这样以后在终端中输入python即可直接进入Anaconda的Python版本(如果你的系统中之前安装过Python,自行选择yes or no)。安装成功后,会有当前用户根目录下生成一个anaconda2的文件夹,里面就是安装好的内容

查询安装信息

$ conda info

查询当前已经安装的库

$ conda list

安装库(***代表库名称)

$ conda install ***  

更新库

 $ conda update *** 

Anaconda仓库镜像

官方下载更新工具包的速度很慢,所以继续添加清华大学 TUNA提供的Anaconda仓库镜像,在终端或cmd中输入如下命令进行添加

$ conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
$ conda config --set show_channel_urls yes

$ conda install numpy   #测试是否添加成功

之后会自动在用户根目录生成“.condarc”文件,Ubuntu环境下路径为~/.condarc,Windows环境下路径为C:\用户\your_user_name\.condarc

channels:
 - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
 - defaults
show_channel_urls: yes

如果要删除镜像,直接删除“.condarc”文件即可

Tensorflow安装

在终端或cmd中输入以下命令搜索当前可用的tensorflow版本

$ anaconda search -t conda tensorflow

选择一个较新的CPU或GPU版本,如jjh_cio_testing/tensorflow-gpu的1.0.1版本,输入如下命令查询安装命令

$ anaconda show jjh_cio_testing/tensorflow-gpu

Using Anaconda API: https://api.anaconda.org

To install this package with conda run:
     conda install --channel https://conda.anaconda.org/jjh_cio_testing tensorflow-gpu

使用最后一行的提示命令进行安装

$ conda install --channel https://conda.anaconda.org/jjh_cio_testing tensorflow-gpu

Package plan for installation in environment /home/will/anaconda2:

The following packages will be SUPERSEDED by a higher-priority channel:

    tensorflow-gpu: 1.0.1-py27_4 https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free --> 1.0.1-py27_4 jjh_cio_testing

Proceed ([y]/n)? 

conda会自动检测安装此版本的Tensorflow所依赖的库,如果你的Anaconda缺少这些依赖库,会提示你安装。因为我之前已经安装过了,所以这里只提示我安装Tensorflow。输入y并回车之后等待安装结束即可

  • 可以选择次高版本的Tensorflow安装,因为最新版本可能清华 TUNA的仓库镜像库没有及时更新,而官方更新连接总是失败,我最开始选择了jjhelmus/tensorflow-gpu的1.0.1版本,其他依赖库清华 TUNA的仓库镜像有资源,而到最后jjhelmus/tensorflow-gpu版本的Tensorflow安装包总是下载不下来,尝试20多次之后换了一个1.0.0的版本,终于顺利安装成功

进入python,输入

import tensorflow as tf

如果没有报错说明安装成功。
