Installation problem on Ubuntu 12.10.  I installed the version of Weka provided by the Ubuntu Software Center, but upon entering the command:

       java -Xmx1000M -jar weka.jar

Received the error message:

       Error: Unable to access jarfile weka.jar

Anyone have any ideas on getting past this initial hurdle?   :-)

The Weka MOOC will use version 3.6.10 as basis for the course. The version available through Ubuntu's repository is 3.6.6, which is too old (repos aren't maintained by Waikato or Pentaho).

Just download the zip file ("other platforms") of 3.6.10 from the Weka homepage (http://www.cs.waikato.ac.nz/ml/weka/downloading.html), unzip it, change into the newly created "weka-3-6-10" directory and issue the following command:
  java -Xmx1g -jar ./weka.jar

BTW make sure you have a JDK/JRE from Oracle installed. OpenJDK does not work properly.

Cheers, Peter

Rafael,
try to change directory to wherever you unzipped weka before executing that command OR give the full path to weka.jar

you can also create a Unity launcher by creating a .desktop file in ~/.local/share/applications with the following content (replacing "/opt/weka" with the directory you unzipped weka into). I called my file weka.desktop

#!/usr/bin/env xdg-open

[Desktop Entry]
Type=Application
Name=Weka
Exec=java -Xmx1000M -jar /opt/weka/weka.jar
Icon=/opt/weka/weka.ico
Categories=Application;
Name[en_GB]=Weka


Double-click this file to start the weka GUI chooser.
You can then lock weka to the Unity launcher

Cheers, Adam

Just make sure you're installing 3.6.10.

I've tried to install the OS X Java 1.6 weka instance over several downloads and when the DMG unpacks and I try run weka-3--6-10-apple.jvm.app the system tells me the application is damaged and should be removed.

Apple Help says "The app’s code does not match the original code that was signed. The app has been modfied [sic], it may be broken, corrupted, or tampered with."

See Weka's troubleshooting page "OSX Mountain Lion - Weka x-y-z is
damaged and can't be installed. You should eject the disk image":

I installed on Suse but should be similar.

1. unzip the downloaded zip file
2. in a terminal window change directory to the location you unzipped the file
3. type the "ls" command ....you should see weka.jar (and other files)
4. type "java --version"......to verify java is installed 
5. type the command shown on the download page
    java -Xmx1000M -jar weka.jar

The window should show on your desktop

What browser are you using?  I had two problems: chrome did not work.  When I tried with Firefox it went flawlessly.  The second mistake I made was the X86 vs the X64 from Windows.  After that, it all went well.

Start Weka from the menu using the "Weka 3.6 (with console)" menu
item. This will leave the command prompt open after Weka exits and
should (hopefully) display an error message. Please post a screenshot
of that screen.

You only need the 64-bit version of the Java runtime environment if
you want to allocated more than 2GB of RAM (in practice, you can only
grab about 1.4GB for a Java process on Windows and 1.7GB on Linux).
Weka (as in "weka.jar") itself can be run on 32 or 64 bit.

> Have tried running weka with console but still the same issue persists :(

Follow these steps:
1. open a command prompt -- there should be a "Command prompt" menu
item under accessories or somewhere similar. As an alternative, you
can simply bring up the "Run" box from the start menu (or whatever
that is nowadays), enter "cmd" and hit the Return key.
2. change into the directory that you installed Weka in, e.g.,
"C:\Program Files\Weka-3-6-10" using the "cd" command:
cd "C:\Program Files\Weka-3-6-10"
3. start Weka with the following command (the file "weka.jar" must be
present in this directory):
java -jar weka.jar

If you get any error messages, post a screenshot.

NB: I haven't been a Windows user for many years. Hopefully, some
other Windows users can help you out with the details.

Can you please elaborate on "not working"? Did the Java installation
(which the Weka installer launches) fail? Is "java -version" still not
working?

Did you confirm that Java got installed by navigating to the directory
that you installed it in?
You should have a directory similar to the following one, containing
the java and javaw executables:
C:\Program Files\Java\jdk1.7.0_40\bin

Prashanth,
   I had a similar problem. Please close all your browsers before you start.
   And then Install Weka with the JRE.

   1. First it will start installing Weka.
    2. When it starts to install JRE at the end. Please make sure this steps goes through successfully.

You can clean the buffers by right clicking on them.  For the others I admit I am doing it the same way as you did.  Made a mess with my first run at the interim test because of this.

Simply remove the result buffers by selecting them and hitting delete. Otherwise, just close the Explorer and reopen it. You don't have to restart Weka itself.

on my system at least (OS X), there does not seem to be a way to clear all the buffers in one fell swoop. i can only delete one buffer at a time, which gets tedious when there are more than a couple.

it's good to know that closing the Explorer also resets it, however it also resets the window position and the current working directory.

hence my suggestion that it would be great if there was a single command that simply resets the Explorer in place...

Combination of using the space bar and the delete key is quite quick.

If you can start Weka using the RunWeka.bat batch file, then you can simply create a new shortcut to this batch file.

Wondering about the absence of a couple of my favourite algorithms from Weka - namely MCMC and Conjugate Gradient.

They are both general purpose and powerful, seem like they would make good additions.

Neither of these algorithms is covered in the MOOC, which is intended as an introduction to data mining and the facilities that Weka offers.

Discussions of what Weka does and doesn’t offer, and why, should take place on the Weka email list (http://weka.wikispaces.com/Weka+Mailing+List) rather than this list, whose purpose is solely to support the MOOC.

cheers
ian

P.S.
To address your question, my understanding is that MCMC (Markov chain Monte Carlo) algorithms are used in machine learning primarily to compute approximate probability estimates from probability distributions, mainly those represented by Bayesian networks. Weka's Bayesian network classifiers (which are not covered in this MOOC) assume complete data (i.e. no missing values), which means that exact inference (i.e. computation of probability estimates) is trivial and very fast. If missing values do occur in the data, they are imputed using ReplaceMissingValues, which is a hack but appears to work reasonably well in practice.

Conjugate gradient descent is an optimization method. This MOOC uses Weka 3.6, but recent versions of Weka 3.7 do have an implementation of a particular variant of non-linear conjugate gradient descent (in weka.core.ConjugateGradientOptimization). It can currently be used to optimize the parameters of (a) logistic regression models using weka.classifiers.functions.Logistic and (b) multi-layer perceptrons for classification and regression (as implemented in the multiLayerPerceptrons package for WEKA 3.7).

They are both general purpose and powerful, seem like they would make good additions.

Go for it! That’s what open source software is all about.


Thanks!

Do you have a Shortcut key list for WEKA?  Is it possible to include the ability to use the "Enter" keyboard key as a shortcut to acknowledge the "OK" button on forms and other default actions.  Would be very user friendly.

Hello Mr. Chiluka,

        I think the problem is with the java version, which is installed on your PC. Can you please give us more information regarding the version of Weka you have installed or trying to install?

You can refer to this link for the supporting Java versions: http://www.cs.waikato.ac.nz/ml/weka/requirements.html

Also make sure you have downloaded a stable version of Weka: http://weka.wikispaces.com/Weka+download+problems

Hi Dayakar,

Try downloading the Weka with Java.

- 32 bit: http://sourceforge.net/projects/weka/files/weka-3-6-windows-jre/3.6.11/weka-3-6-11jre.exe/download?use_mirror=jaist

- 64 bit: http://sourceforge.net/projects/weka/files/weka-3-6-windows-jre-x64/3.6.11/weka-3-6-11jre-x64.exe/download?use_mirror=jaist

As suggested by Sid, you can check the version of Java by typing at the command prompt:
java -version
if it says that can not recognized java as an internal or external command, then you need to put your java into classpath.

Weka is a Java program and it needs Java to run successfully.
Is Java in your path?
To check: open your command prompt and type "java -version" (without the quotes).
If the commands returns an error message then either you don't have Java installed or Java is not in your path. If you are not sure how to do it then the easiest way is to download Java and install it.

I tried running Weka with Java 6, 7 and 8 pre-installed. So, I suppose you can run it without problem with these 3 versions. If your Java is older than 6 then you need to upgrade it.

Quick question. I have received an assignment to train a RBF network with 1 to 20 layers. As far as my knowledge goes, RBF networks only have 1 layer, right? Am I misunderstanding RBFs? IF a multilayer RBF is possible in WEKA, how do I set it up?

Cheers

Questions about Weka that aren't related to the MOOC are best posted on the Weka mailing list instead. See Weka homepage for details.

Have you tried downloading again, but from a different mirror?

Just tried it and confirmed that the following 32-bit download of
3.8.1 with JRE is corrupt:
https://sourceforge.net/projects/weka/files/weka-3-8/3.8.1/weka-3-8-1jre.exe/download

Instead, download/install 3.8.1 without bundled Java JRE:
https://sourceforge.net/projects/weka/files/weka-3-8/3.8.1/weka-3-8-1.exe/download

If you haven't got Java installed on your machine already, just
download/install it separately. You can obtain Java from the Oracle
website:
http://www.oracle.com/technetwork/java/javase/downloads/index.html

At the time of writing, the following is the latest version of Java 8 (u121):
http://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

NB: "i586" means 32bit and "x64" is 64bit.
