How to Download and Install WEKA on Windows & Mac OS X

I have been doing a big data course since January 2018. Here in Sweden, lab works/projects are some of the ways that students use to learn. Most of the courses that are being offered, always have practicals/lab works/assignments that accompanies them. It is done this way so that it will enable students to learn themselves and also understand the courses better. I personally feel it is a very good way of making students acquire more knowledge and do things in a better way. Some of these lab works can be really challenging and difficult. However, they have made me to learn a lot within a short period of time.

In my first masters, we used rapid miner for our data mining projects. It was a good experience for me even though I didn't document it😭but I enjoyed all the projects we worked on and I learnt a lot. This time around, I decided not to make the same mistake, so I will be documenting all the team projects we will be working on. This will help me in the future if I need to revise any of the projects, as I have a great interest in data mining. Aside that, I also believe that this piece will be useful for any newbie trying to lay hands on data mining projects.

So the first lesson is on how to install WEKA (a machine learning software to solve data mining problems) on windows & Mac OS X. Lets's dive right into it 👇👇👇

Part A: How to Install WEKA on Windows (I use a windows 10 OS)
  • Go to WEKA homepage and download the version that you want.
  • I downloaded the 64-bit windows that includes Oracle's 64-bit Java VM 1.8. My version is 3.8 which is the latest stable version (March, 2018). However there are other versions . Be sure to check the right one before downloading it.
  • Follow the default instructions (there is no need to change any of the settings). When the installation is complete, you will see an update as shown below. Click 'finish' and the installation is complete.

  • The WEKA GUI Chooser will be launched and you can start playing around with the interface.

  • The accompanying oracle JAVA installation started automatically after the WEKA intsallation was installed. For the installation, I also picked the default setting as I did for WEKA.
  • A pop-up window will appear with "successfully installed". Click close and that is just it.  Fingers crossed that everything goes well for you as it went well for me. 

  • If you are interested in the tutorials you can click on "next steps" which will take you to a new window of some tutorials. Otherwise that is just the straightforward way to install WEKA on your windows system.

Part B: How to Install WEKA on Mac OS X
  • Unlike windows which had a lot of versions where you decide on the one that works best for you. Mac doesn't have that option, there was only one available version (March, 2018) which was what I downloaded.
  • Furthermore, I discovered that the version (3.9) that I downloaded didn't require any manual installation process as windows. 
  • A package that contained WEKA app and content folder was already inside the downloaded package.
  • All I needed to do was to open the downloaded folder. Yes, it is that straightforward😉

  • However, the WEKA page didn't launch😣 when I tried to open it. I got an "error" message.
  • What then could be the problem and what did I do to solve this problem? All I did was to move the WEKA app into my macbook application folder.
  • After completing that step, I was asked if I was sure that I wanted to launch WEKA. Of course, YES, I am so sure/ready😁 so, I Clicked "open" and that was just it💪

  • The WEKA GUI Chooser interface is exactly the same as windows. After completing the installation process, you can start playing around with it. Fingers crossed that everything goes well for you as it went well for me.

Basically, if you follow the steps above, you should able to install WEKA successfully on your mac book or windows system with little or no help. However, if you tried these steps and it didn't work, do not hesitate to drop your questions in the comment section below and I will try to answer them if I know it😊.

I hope you enjoyed this short tutorial and also learnt one or two things about WEKA installation. Until next time...💋
