为使用Scikit-learn搭建环境(window/Mac)

安装目录###

1. python
2. Ipython
3. qtconsole
4. Numpy
5. Scipy
6. matplotlib
7. scikit-learn

1. 安装 python2.7 (or python3.4)

  • Windows用户
  • 下载,安装
  • 正确设置PATH变量:进入 computer > Control Panel > All Control Panel Items > System > Advanced system setting > environment variables,然后点击 “Path” 然后添加 “;\C:\Python27″(或者Python33)
  • 这样就可以在命令行界面(CLI)打开Python
  • Mac用户
  • Mac自带Python2.7
  • 可以先安装Homebrew,命令$ ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)",然后再安装Python3.4,命令$ brew install python3

2. 安装 Ipython

《为使用Scikit-learn搭建环境(window/Mac)》 Ipython

2.1 整体安装

  • Windows用户
    $ python -m pip install ipython[all]

  • Mac用户
    $ pip install ipython[all]

  • [all] 意味着会下载并安装Ipython以及相关需要的其他包:
    jinja2 needed for the notebook
    sphinx needed for nbconvert
    pyzmq needed for IPython’s parallel computing features, qt console and notebook
    pygments used by nbconvert and the Qt console for syntax highlighting
    tornado needed by the web-based notebook
    nose used by the test suite
    readline (on OS X) or pyreadline (on Windows) needed for the terminal

  • 还有一些不能通过pip安装,需要单独安装比如:Qt, PyQt 和 pandoc

2.2 独立安装

2.2.1 安装Ipython本身

  • Windows用户
    install setuptools
    $ python -m pip install pyreadline
    $ python -m pip install ipython

  • Mac用户
    pip install ipython

2.2.2 安装基础相关包(Basic optional dependencies )

  • readline (for command line editing, tab completion, etc.)
    python -m pip install "ipython[terminal]"

  • nose (to run the IPython test suite)
    python -m pip install "ipython[test]"

  • pyzmq (for IPython.parallel (parallel computing))
    python -m pip install "ipython[parallel]"

  • notebook (Dependencies for the IPython HTML notebook)
    python -m pip install "ipython[notebook]"

  • IPython notebook使用web的形式,使用时输入ipython notebook

  • 支持IPython notebook的浏览器有:
    Chrome ≥ 13
    Safari ≥ 5
    Firefox ≥ 6

  • Ipython notebook貌似还挺强大的,这里来不及深入,以后有时间会好好研究一下

更多信息,参考Ipython官网

3. 安装 qtconsole

包含:pyzmq、pygments 和 PyQt(or PySide)

$ pip install pyzmq pygments
Shortcut:
$ pip install "ipython[qtconsole]"

PyQt/PySide不能通过pip安装

4. 安装 Numpy

5. 安装 Scipy

6. 安装 matplotlib

《为使用Scikit-learn搭建环境(window/Mac)》 matplotlib

matplotlib是基于numpy的一套Python工具包,提供了丰富的数据绘图工具。

注: 使用命令pip list查看除了matplotlib你是否还安装了:
setuptools
numpy
Python-dateutil
pytz
pyparsing

7. 安装 scikit-learn

《为使用Scikit-learn搭建环境(window/Mac)》 scikit-learn

  • scikit-learn是用于机器学习的Python工具包
  • 为数据挖掘和数据分析提供简单高效的工具

  • 基于NumPy, SciPy, 和 matplotlib

  • 开源,BSD license

  • Scikit-learn需要环境:
    Python (>= 2.6 or >= 3.3)
    Numpy (>= 1.6.1)
    Scipy (>= 0.9)

  • Windows用户
    python -m pip install -U scikit-learn

  • Mac用户
    pip install -U scikit-learn

大功告成,play with data and have fun!
