How to increase heap size in weka3.6?

10 October 2012 1 2K Report

I tried increasing heap size by editing RunWeka.ini file and changed it to 1024m from 256m. I am using large dataset. After changing the file I saved it and ran WEKA again. But still I am getting the error. Is that the change was not taken or 1024m is not enough. Then how to increase further?

You need to open the program with following command;

java -Xmx6g your/program/path

This command tries to allocate 6g memory

Change the value accordingly like 160M -> 160 mb or such
