上一篇“在linux上安装机器学习开发环境”文章演示了在centos下设置机器学习环境. 本篇讨论如何在mac下配置相关环境.
Anaconda介绍在上篇中有, 在此不再重复. Anaconda 安装包可以到 https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/ 下载。
我下载的是4.3.1
zhh@zmac ~ $ wget -c https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/Anaconda3-4.3.1-MacOSX-x86_64.sh
wget -c 参数支持断点续传
zhh@zmac ~ $ bash Anaconda3-4.3.1-MacOSX-x86_64.sh

installation finished.
Do you wish the installer to prepend the Anaconda3 install location
to PATH in your /Users/zhh/.bash_profile ? [yes|no]
[yes] >>>
Prepending PATH=/Users/zhh/anaconda3/bin to PATH in
newly created /Users/zhh/.bash_profile
For this change to become active, you have to open a new terminal.
Thank you for installing Anaconda3!
详细列出了会缺省安装的相关包. 缺省也会添加路径到.bash_profile中.如果用的是zsh,可以手工在.zshrc中添加路径
zhh@zmac ~ $ vi .zshrc
