When the machine learning model is deployed across platforms using PMML, the error occurs when the model is loaded in Java

Reason: the jar package version of Java does not match the PMML file version. The jar package version is too low to parse the PMML file. If you upgrade the jar package, the current syntax of the loading model is not available; Therefore, it is safe and reliable to reduce the version number of PMML files.

Solution: change xmlns = “…/pmml-4_4” in PMML file to xmlns = “…/pmml-4_3”

Run again, successful.
