Hi,

Try to replace 0 with a value near 0 like 0.00000000001

Hi,

After Predictor node use Rule engine node

$YourColumnName$ = 0 => 0.0000001
TRUE => $YourColumnName$

Hi,

just to clarify, the error is not about MAE (Mean Absolute Error), which is still usable with 0 target values, but about MAPE (Mean Absolute Percentage Error). The question ist, if MAPE is the right metric with 0 targets…

Best regards,
