regression predictor failed: no match found

[JScheidegger]

Hi, guys, I did design a very simple workflow that performs a linear regression (on 2667 rows of data already cleaned and organized, with 34 variables, all numeric, double or integer) and it definitely gets a resulting model (green lamp on). The regression learner is followed by a regression predictor which receives connections from the learner node (blue box) and from the same data which was fed to the learner (predictor starts with a yellow lamp when connected). When I ask the predictor to run I get a message ERROR Regression Predictor 0:19 Execute failed: No match found, where 19 is the predictor node. Any clue of what might be wrong?

What does it means? My workflow is pretty straightforward: Read Excel file => Normalize the data => Partition it 80%-20% => Logistic regression learner for the 80% of the data => Apply it on the 20% remaining. The Learner works but not the predictor, why? I someone could help me, I would be very …

Wow! You got right into the point! I would never figure out what the cause was, and even less would know how to fix it. Thank you very, very much!
