Ubuntu 22.04 anaconda pip换阿里源

1. 打开终端，输入以下命令安装anaconda和pip：

   wget https://repo.anaconda.com/archive/Anaconda3-2021.11-Linux-x86_64.sh
   bash Anaconda3-2021.11-Linux-x86_64.sh
   source ~/.bashrc
   conda update conda
   pip install -U pip

2. 输入以下命令修改pip的源为阿里云源：

   mkdir ~/.pip
   touch ~/.pip/pip.conf
   echo "[global]" >> ~/.pip/pip.conf
   echo "index-url=https://mirrors.aliyun.com/pypi/simple/" >> ~/.pip/pip.conf
   echo "[install]" >> ~/.pip/pip.conf
   echo "trusted-host=mirrors.aliyun.com" >> ~/.pip/pip.conf

3. 输入以下命令验证pip源是否修改成功：

   pip config list

如果输出中有以下内容，说明成功修改为阿里云源：

   global.index-url='https://mirrors.aliyun.com/pypi/simple/'
   install.trusted-host='mirrors.aliyun.com'
