Day14 summary

Since I am writing blog in Ubuntu which has not installed Chinese language package, this blog will be in poor English.

It's terrible to run into problem or bug one by one these days. But it's lucky to have two solved today.

The problem list:

1. Failed to install pandas package. I tried easy_install, pip and python setup. They all seemed to encounter the same problem, like "no files found matching 'README.rst'"... I can't remember it clearly and forgot to get screenprint.

2. Try Ipython and always get"[TerminalIPythonApp] Error in enabling GUI event loop integration:". It's useless to search solution for this. And it turns out i ignore the important error info at the end of the a series of error info. it's  "ImportError:Matplotlib backend_wx and backend_wxagg require wxPython >=2.8", and last i search that and get perfect answer on stackflow http://stackoverflow.com/questions/5121574/wxpython-import-error.

I say it's perfect solution for that pandas got installed successfully after Ipython problem solved.

3. There is some error in Chapter 5 of <Programming Collective Intelligence>, specificlly on page about genetic algorithm. lucky to get some suggestion on the errata webpage of the book http://www.oreilly.com/catalog/errataunconfirmed.csp?isbn=9780596529321. but i still feel confused about the improvement. I think it's necessary to refer to some genetic algorithm materials.

4. ebay API has changed and i have to learn it to get the practice in Chapter 8 done.

All right, i know it's hard to get what the blog means, but I just note it here for further reference. Good Night.
