一、下载最新Anaconda版本两种方法
1.Anaconda官网
官网 之前一篇有介绍怎么下载点击。
2.清华大学开源软件镜像站 https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/?C=M&O=D 清华镜像源网站
二、Anaconda环境里下载速度都比较慢
输入conda info查看一些信息
(base) C:\Users\Administrator>conda info

解决办法：
1.添加国内镜像源 下面解释什么是镜像源 运行Anaconda Prompt
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/
conda config --add channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
2.设置启动设置好的国内镜像源 conda config --set show_channel_urls yes
3.查看是否添加上了源 conda config --show
4.如果镜像源失效了，或者想换成其他的源，怎么删除呢？ conda config --remove channels https://mirrors.ustc.edu.cn/anaconda/pkgs/free/ conda config --remove channels https://mirrors.ustc.edu.cn/anaconda/pkgs/main/
(pytorch36) C:\Users\Administrator>conda config --add channels https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/

补充：镜像源 镜像：比如你照镜子，里面的成像，这里的镜像，是一种文件格式，是镜像文件的简称，举例，你租房时房东给你了一把钥匙A，你出于各种目的（怕丢，给女友，给小伙伴）又配了一把钥匙B，这两把钥匙从功能上都能开你家的门，钥匙B就是钥匙A的镜像。 源（来源）：下载软件一般来源都是网站，网站存储在服务器上，有的服务器在国内，有的在国外。 镜像源：镜像的来源，一般指国内存放国外软件镜像的网站、服务器。为啥需要镜像源，在国内由于各种原因下载或更新国外的软件（比如python）网速特别慢甚至连不上。Ubuntu、Python、Nodejs、MySQL、Git、Chromium、Docker、Homebrew 等一系列的常用开源系统、软件都是国外开发的，下载地址位于国外，从国内访问、下载、更新。所以找个镜像网站就解决了。
目前有那些镜像源
清华源 https://mirrors.tuna.tsinghua.edu.cn/
腾讯源 https://mirrors.cloud.tencent.com/
阿里源 https://developer.aliyun.com/mirror/
华为源 https://mirrors.huaweicloud.com/home
网易源 http://mirrors.163.com/
淘宝 NPM 镜像 https://developer.aliyun.com/mirror/NPM
豆瓣 Python PyPI 镜像 http://pypi.doubanio.com/simple/
中国科技大学 https://pypi.mirrors.ustc.edu.cn/simple/
中国科学技术大学 http://pypi.mirrors.ustc.edu.cn/simple/
%%比如使用方法：以Python环境下pip安装keras为例
pip install keras==2.3.1 -i http://pypi.douban.com/simple/
//2.3.1为所需版本号，尾部url为对应镜像源地址
访问速度方面，大型商业公司、尤其是云服务商（没错，指的是腾讯源、阿里源和华为源）的镜像站会做得更好，毕竟钱多、基础设施广。
三、更新conda
代码和显示如下
