ubuntu 20.04 | 安装 Anaconda3

1. 下载Anaconda3安装包

#指定下载位置/home/dong/Downloads/install-package
sudo wget -P /home/dong/Downloads/install-package https://repo.anaconda.com/archive/Anaconda3-2020.11-Linux-x86_64.sh

如果下载速度过慢，可以使用清华大学开源软件镜像站：

sudo wget -P /home/dong/Downloads/install-package https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-2020.11-Linux-x86_64.sh

2. 验证脚本的数据完整性

sha256sum /home/dong/Downloads/install-package/Anaconda3-2020.11-Linux-x86_64.sh

确保输出的哈希值和Anaconda with Python 3 on 64-bit Linux页面对应版本的Anaconda哈希值一样

3. 运行脚本

bash /home/dong/Downloads/install-package/Anaconda3-2020.11-Linux-x86_64.sh

全程yes，回车

4. 激活Anaconda3

source ~/.bashrc

5. Anaconda3替换国内源

5.1 修改用户目录下的.condarc

sudo gedit ~/.condarc

.condarc中加入下列内容：

channels:
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/main/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/pkgs/free/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/conda-forge/
  - https://mirrors.tuna.tsinghua.edu.cn/anaconda/cloud/pytorch/
ssl_verify: true

5.2 修改.condarc文件权限

sudo chmod 777 ~/.condarc

5.3 清除索引缓存

conda clean -i 

5.4 输入命令检查channels

conda config --show channels

6. 升级Anaconda3

conda update --all
conda update conda
conda update anaconda

7. 去除终端base

conda config --set auto_activate_base False
source ~/.bashrc

8. 卸载 Anaconda

8.1 删除Anaconda相关目录/文件：

sudo rm -rf ~/anaconda3 ~/.condarc ~/.conda ~/.continuum

8.2 修改.bashrc文件：

• 打开.bashrc文件

  sudo gedit ~/.bashrc
  

• 删除下列内容

  # >>> conda initialize >>>
  # !! Contents within this block are managed by 'conda init' !!
  __conda_setup="$('/home/dong/anaconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
  if [ $? -eq 0 ]; then
      eval "$__conda_setup"
  else
      if [ -f "/home/dong/anaconda3/etc/profile.d/conda.sh" ]; then
          . "/home/dong/anaconda3/etc/profile.d/conda.sh"
      else
          export PATH="/home/dong/anaconda3/bin:$PATH"
      fi
  fi
  unset __conda_setup
  # <<< conda initialize <<<
  

8.3 激活环境

source ~/.bashrc
