1. Anaconda and Miniconda 镜像

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 and 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。

即可添加 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。

由于更新过快难以同步，我们不同步 pytorch-nightly, pytorch-nightly-cpu, ignite-nightly 这三个包。
