Re: AutoWEKAClassifier

Hi,

Sorry for the late reply.

I was trying to reproduce the error you mentioned. Currently, it looks working fine on my ubuntu 20.04 and windows 10 with openjdk 11 and bundled java runtime (ZuluFX).

One thing I should mention that auto-weka will make a command call for running its evaluator while running. Please make sure that you can invoke “java” in your terminal environment as well. If it still not work, please send me your running environment such as the version of OS, JDK, WEKA, and a log file if possible. I will try to reproduce the error.

Cheers,
Justin
