Anaconda/Miniconda 镜像 - 清华大学开源软件镜像站
https://mirror.tuna.tsinghua.edu.cn/help/anaconda/
Anaconda 是一个用于科学计算的 Python 发行版，支持 Linux, Mac, Windows, 包含了众多流行的科学计算、数据分析的 Python 包。
Miniconda 是一个 Anaconda 的轻量级替代，默认只包含了 python 和 conda，可以通过 pip 和 conda 来安装所需要的包。
1.1 Anaconda/Miniconda 安装包下载Anaconda 安装包可以到 https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/ 下载。
Miniconda 安装包可以到 https://mirrors.tuna.tsinghua.edu.cn/anaconda/miniconda/ 下载。
1.2 .condarc 文件TUNA 提供了 Anaconda 仓库与第三方源 (conda-forge、msys2、pytorch 等) 的镜像，各系统都可以通过修改用户目录下的 .condarc 文件，添加 Anaconda Python 免费仓库。运行 conda clean -i 清除索引缓存，保证用的是镜像站提供的索引。

Windows 用户无法直接创建名为 .condarc 的文件，可先执行 conda config --set show_channel_urls yes 生成该文件之后再修改。
