Re: Heap size

The screenshot shows that your maximum heap size is 1006 MB, which is
really quite small.

I use the _JAVA_OPTIONS environment variable to increase the maximum heap
size:

  https://waikato.github.io/weka-wiki/faqs/OutOfMemoryException/

This option work with the Zulu Java virtual machine that is included in the
WEKA distribution.

On Windows, in the main Windows search bar, search for

  environment variables

and choose

  Edit environment variables for your account

(or, alternatively, change the variables for everyone using the system).
Then, make a new variable with name

_JAVA_OPTIONS

and set the variable value to

-Xmx4g

or similar (4g would specify a maximum heap size of 4 gigabytes).

Make sure that the heap size you specify does not exceed the amount of RAM
on your computer. Otherwise, your WEKA may start to run very slowly...

Cheers,
Eibe
