Hello guys,
I have a simple flow that includes the following nodes: Missing Value, Decision Tree Learner and PMML Writer. Execution of the PMML Writer node fails with the following error:
"ERROR PMMLValidator <DerivedField dataType="integer" name="bin_variable1_[...]: Expected attribute: optype in element DerivedField"
I have attached an image of the knime workflow.
I will appreciate any help or suggestions.
Thanks,
Bart
