Hi @Slyart2046

Can you maybe give us some more information? It would help to see your whole process and data to reproduce this.

Maybe you can also share your Studio log file (can be found in the .RapidMiner folder in your home directory)? Either here or as a PM.

Cheers

Jan

Hi again,

from what I can see, this comes from setting the confidence parameter of the tree learner to either 0 or 1, wich should not be possible in the UI, since the parameter is restricted to a value between 0.0000001 and 0.5. Would be interesting to see your process. Are you using a macro to set this value by any chance?

Cheers

Jan
