Thank you for your reply. I'm using KNIME version 2.12.1 running on a GNU/Linux (Ubuntu 14.04) OS. As far as I know KNIME is using the bundled Java version 1.7.0. Is there something I can do to solve this problem?
I have no clue why this error occurs on your system, but maybe you can use one of the other predictors? We also have a PMML Predictor node and a Compiling PMML Predictor in KNIME Labs.
I came back to this issue because I just realized that this problem appears and disappears (apparently randomly) from one KNIME session to another. This means that sometimes the JPMML classifier node gives the problems and cannot be run, and sometimes if you just restart KNIME, it correctly works. Is it possible that this depends on the order by which dependencies are loaded? Is there a way to avoid the problem?
Hi,
thank you for reporting this. That it occurs kind of randomly really suggests that there is a problem with conflicts with other dependencies. I will have a chat with some other developers and see what their opinion is.
Kind regards,
Alexander
