Python数据分析 EPD

参考用书 《利用Python进行技术分析：Python for Data Analysis》

官方把epd (https://www.enthought.com/products/canopy/package-index/) 升级为Canopy(https://www.enthought.com/products/canopy/package-index/)，为了尽可能和书籍一致，只能去其他地方想办法了

从这里下载离线镜像 http://mirror.seas.harvard.edu/epd/enthought.com/repo/free/

$wget http://mirror.seas.harvard.edu/epd/download.enthought.com/epd_free/epd_free-7.2-2-rh5-x86_64.sh

安装：http://courses.cs.washington.edu/courses/cse140/12su/computing-resources.html

#chmod u+x epd_free-7.2-2-rh5-x86_64.sh

$.epd_free-7.2-2-rh5-x86_64.sh

先让你接受协议，然后指定安装路径，如~/epd会自动安装依赖如下：

As the last step, you should edit your .bashrc or prepend
    the EPD_free install path:

/home/jp/epd/bin

Thank you for installing EPD_free!

然后安装padas

#sudo easy_install pandas

Error 1:

pkg_resources.VersionConflict: (numpy 1.6.1 (/home/jp/epd/lib/python2.7/site-packages), Requirement.parse('numpy>=1.7.0'))

$sudo pip install --upgrade numpy>=1.7.0

Error 2:

# Extra version check in case wxversion lacks AlreadyImportedError;
ImportError: Matplotlib backend_wx and backend_wxagg require wxPython >=2.8
#sudo pip install --upgrade wxPython>=2.8

http://stackoverflow.com/questions/5121574/wxpython-import-error
$sudo apt-get install libjpeg62 

Error 3:

UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 72: ordinal not in range(128)
$sudo apt-get install libevent-dev python-dev

安装pandas

#sudo easy_install pandas
gcc编译 ,时间会比较久

安装完成后，

$ipython --pylab

import pandas

Error 4:ImportError: No module named pandas

检查了下原因，pandas确实是已经装了，只不过没有装在epd/bin下， epd/bin下的Python版本是2.7.2

系统自带的python 是2.7.6 ,结果把pandas装在系统自带的Python site-packages里了。现在就卡在这一步，先记录到这里再说。
