anaconda python更换清华源

前言

在使用anaconda python环境过程中你会发现使用conda下载包的速度非常的慢，因为使用的是国外的服务器，所以这里要设置为国内的镜像。使用下面的配置命令即可：

添加Anaconda的TUNA镜像

conda config --add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'      //TUNA的help中镜像地址加有引号，需要去掉# 
conda config --add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/'
conda config --setshow_channel_urls yes      //设置搜索时显示通道地址

添加后

(base) C:\Users\aikera>conda config --show channels
channels:
  - 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/'
  - 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'
  - defaults
  - conda-forge

还有简单粗暴地方法：直接修改conda的配置，一般在当前用户路径下，比如C:\Users\Administrator.condarc
.condarc具体内容如下：

channels:
  - 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/'
  - 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'
  - defaults
  - conda-forge

验证

conda config --show

测试：

安装numpy试试：

(base) C:\Users\aikera>conda install numpy
