Downloading and installing Weka

• Snapshots

  Every night a snapshot of the Subversion repository is taken, compiled and put together in ZIP files. For those who want to have the latest bugfixes, they can download these snapshots here.

• Stable book 3rd ed. version

  Weka 3.6 is the latest stable version of Weka, and the one described in the 3rd edition of the data mining book. This branch of Weka receives bug fixes only (for new features in Weka see the developer version). There are different options for downloading and installing it on your system:

  • Windows x86

    Click here to download a self-extracting executable that includes Java VM 1.6
    (weka-3-6-7jre.exe; 37.3 MB)

    Click here to download a self-extracting executable without the Java VM
    (weka-3-6-7.exe; 22.5 MB)

    These executables will install Weka in your Program Menu. Download the second version if you already have Java 1.5 (or later) on your system.

  • Windows x64

    Click here to download a self-extracting executable that includes 64 bit Java VM 1.6
    (weka-3-6-7jre-x64.exe; 37.6 MB)

    Click here to download a self-extracting executable without the Java VM
    (weka-3-6-7-x64.exe; 22.5 MB)

    These executables will install Weka in your Program Menu. Download the second version if you already have Java 1.5 (or later) on your system.

  • Mac OS X

    Click here to download a disk image for OS X
    (weka-3-6-7.dmg; 29.0 MB)

  • Other platforms (Linux, etc.)

    Click here to download a zip archive containing Weka
    (weka-3-6-7.zip; 22.8 MB)

    First unzip the zip file. This will create a new directory called weka-3-6-7. To run Weka, change into that directory and type

    java -jar weka.jar

    Note that Java needs to be installed on your system for this to work. Also note, that using -jar will override your current CLASSPATH variable and only use the weka.jar.

• Developer version

  This is the trunk of Weka and continues from the stable-3-6 code line. It receives both bug fixes and new features.

  • Windows x86

    Click here to download a self-extracting executable that includes Java VM 1.6

    (weka-3-7-6.exe; 22.5 MB)
