Hi,

Apologies for the delay in reply.

Please ensure that the WEKA JAR file is stored locally somewhere, and that its directory is added to your Java CLASSPATH (https://docs.oracle.com/javase/tutorial/essential/environment/paths.html).

Once done, please try testing one of the examples again to make sure they run correctly. Does this help address your issue?

$export CLASSPATH=/home/your_dir/weka-3-9-3/weka.jar
$echo ${CLASSPATH}
$python3 testwekapy.py
