Not enough memory (less than 50 m on heap) error message in weka 3.8

Question

I am using weka 3.8. when I apply association rules on my dataset, an error message appears which says that (not enough memory. less than 50m left on heap. please load a smaller dataset or use a larger heap size).

Answer 1

In your RunWeka.ini you can change

javaOpts=%JAVA_OPTS%

to

javaOpts=%JAVA_OPTS% -Xmx2048m

The parameter -Xmx says how much memory your vm is allowed to use.

See https://docs.oracle.com/en/java/javase/16/docs/specs/man/java.html for more info about this and other parameters.
