anaconda python更換清華源

前言

在使用anaconda python環境過程當中你會發現使用conda下載包的速度很是的慢，由於使用的是國外的服務器，因此這裏要設置爲國內的鏡像。使用下面的配置命令便可：

添加Anaconda的TUNA鏡像

conda config --add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/'      //TUNA的help中鏡像地址加有引號，須要去掉# 
conda config --add channels 'https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/'
conda config --setshow_channel_urls yes      //設置搜索時顯示通道地址

添加後

(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

還有簡單粗暴地方法：直接修改conda的配置，通常在當前用戶路徑下，好比C:\Users\Administrator.condarc
.condarc具體內容以下：

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

安裝numpy試試：
