I launched JRip on a data set which contains both numeric and nominal variables (the class is nominal). Weka experiment environment returns the following message:

"Can't normalize array. Sum is zero"

Can someone explain what it means?

Thanks a lot!!

Can you tell me which version of Weka and perhaps provide the data set that caused the error?

Cheers,
Mark.

My version is Weka 3.5.2.

Lots of bugs have been fixed since 3.5.2. I'd suggest upgrading to 3.5.7.

Let me know if the problem persists after this upgrade. If so, I will probably need your data set and experiment configuration file.

Cheers,
Mark.
