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：
Do you approve the license terms? [yes|no]
[no] >>> yes

done.
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:

Error 3:

$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。
