Check memory available

You can easily check, how much memory WEKA can use (this depends on the maximum heap size the Java Virtual Machine was started with).

• SimpelCLI

  • start the SimpleCLI

  • run the following command:

    java weka.core.SystemInfo

  • the property memory.max lists the maximum amount of memory available to WEKA

• GUIChooser

  • select Help -> SystemInfo
  • the property memory.max lists the maximum amount of memory available to WEKA

In case you should run into an OutOfMemoryException, you will have to increase the maximum heap size. How much you can allocate, depends heavily on the operating system and the underlying hardware, see the Java Virtual Machine article). Also, have a look at the OutOfMemoryException section further down.
