Welcome to:

CSE 891: Computational Techniques for Large-Scale Data Analysis for MSBA (Spring 2014)

This blog will contain additional information and material for the course. It should provide a point of reference, and allows you to discuss the material online. I find it very important that questions should be made public. It helps others to discover questions they might not have thought about, and by comparing the solution I give to these problems with your own approaches you can better evaluate your own understanding of the topic.

    I installed iPython Notebook version 2.7 through Anaconda. It seems to be installed but when I open it a blank screen (like putty but no prompt) pops up. There is a blinking cursor but when I type, nothing happens. I wonder if I did something wrong or if I don’t know how to use it yet?

      I assume you installed it on windows?
      Try opening a browser and use this url:

      also you need to run it by right clicking and then “run as administrator”

        Yes I installed it on Windows. I opened it, ran it as administrator, and the same screen popped up, so I don’t think that is the issue. I then pasted the url into firefox and it said this message:

        Unable to connect

        Firefox can’t establish a connection to the server at

        The site could be temporarily unavailable or too busy. Try again in a few moments.
        If you are unable to load any pages, check your computer’s network connection.
        If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

        However, now I looked back at iPython Notebook and it has a list of commands. I can’t post a picture here so I will email you the screenshot. Maybe it is working and I simply don’t know how to use it yet.

        Thanks for the quick reply,

          Now another browser popped open and it appears to be connected to iPython notebook. I think it works and I just don’t know how to use it yet. I sent the other screenshot through msu mail.

            The pic you mailed is exactly how it is supposed to look like, what iPython Notebook does is open a server locally who makes this webpage you are seeing.
            All interactions happen now through that browser window. I will of cause give an introduction on Monday about how to use all of this

    Hello Prof. Hintz, I have installed Ipython 2.7 (Wakari – In Cloud). There is also a command window available locally.

    Hello Prof.Hintze. I am trying to complete the home work from Lecture 2 (exercise 2) in Arctic (putty).
    When I created a new file and wrote the codes and executed, I get the following messgae: import.im6: unable to open X server `’ @ error/import.c/ImportImageCommand/368.
    import.im6: unable to open X server `’ @ error/import.c/ImportImageCommand/368.
    spider.py: 8: spider.py: Syntax error: word unexpected (expecting “)”)

    Would you please be able to help?

      once you edited the spider.py file and call python spider.py is it showing that error? I am not sure when the error occurs you mention?
      I am in the office right now until 4pm in case you want to come over and let me take a look at it. Otherwise we can talk about this before class tomorrow. Cheers Arend
