I'm new to knime and I encountered this error in JPMML.

 ERROR JPMML Classifier     0:13       Execute failed: Expected FLOAT, but got DOUBLE (0.486205839010216)


This is similar to this issue . The solution is to update the JPMML evaluator. I checked the PMML-evaluator version in my Knime and it is 1.1 only. Is it possible to update this in Knime? How can I update it?

Hi gcalcaraz,

Thank you for reporting this. I have created a ticket to update the JPMML version. Our developers will look into this.

The problem is that the latest versions of JPMML have a different license which conflicts with KNIME's licenses. Therefore we cannot update to a later version at the moment.
