Re: Installing weka on ubuntu

> Many thanks for your email. I knew it was something stupid. The instructions I saw said to run the weka.sh

Ah, I see. I'm an old time Weka user, so didn't know that there was a
script for that now... That weka.sh script worked fine for me though.

> Another question. is there a way I can adjust the amount of memory weka uses? I have a machine with 64gb and want to allow weka to use up to 32

You can use the -Xmx option for that, e.g., using 32GB as heap size:
java -Xmx32g -jar weka.jar

If you want to run classifiers directly, rather than the UI, use
something like this:
java -Xmx32g -cp weka.jar weka.classifiers.trees.J48 <other options>

Using the above script with 32GB heap (from the directory with the weka.jar):
_JAVA_OPTIONS=-Xmx32g ./weka.sh

BTW I'm using the bash shell.

Cheers, Peter
