Python：Anaconda安装以及python包安装

1.Anaconda简介

Anaconda集成了很多的科学计算包，省去了自己安装包的过程。

2.下载

（1）下载页面
https://www.anaconda.com/download/#windows
（2）官方存档页面
https://repo.anaconda.com/archive/

（3）清华镜像版本
https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/

3.Prompt基本操作

（1）检查安装库

conda list
结果

（2）安装一个库

-》先确认可用库名称

anaconda search -t conda tensorflow
结果：
	...
     n-west/tensorflow-cpu     |   1.10.1 | conda           | osx-64          | py35_0
     nehaljwani/tensorflow     |    1.2.1 | conda           | osx-64, win-64  | np112py27_0, py36_0, np112py36_0, np112py35_0, py35_0
                                          : TensorFlow is a machine learning library
     nehaljwani/tensorflow-base |    1.8.0 | conda           | win-64          | py36h1a1b453_0, py35h1a1b453_0
                                          : TensorFlow is a machine learning library, base package contains only tensorflow.
     nehaljwani/tensorflow-gpu |    1.1.0 | conda           | win-64          | np112py36_0, np112py35_0
                                          : TensorFlow is a machine learning library

-》依据上面的结果，选择windows 64的对应库名称

nehaljwani/tensorflow-base

-》查找对应库安装命令

anaconda show nehaljwani/tensorflow-base
结果：
(base) C:\Users\Administrator>anaconda show nehaljwani/tensorflow-base
