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 GUI version

  Weka 3.6 is the latest stable version of Weka. There are different options for downloading and installing it on your system:

  • Windows

    Click here to download a self-extracting executable that includes Java VM 1.5
    (weka-3-6-2jre.exe; 37.3 MB)

    Click here to download a self-extracting executable without the Java VM
    (weka-3-6-2.exe; 20.7 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

  • Other platforms (Linux, etc.)

    Click here to download a zip archive containing Weka
    (weka-3-6-2.zip; 20.9 MB)

    First unzip the zip file. This will create a new directory called weka-3-6-2. To run Weka, change into that directory and type
