TrainImagesRegression

Hello Everyone!
I am facing one issue while training the image regression model. Please have a look at the attached image of log.

Background
I want to predict the Soil’s organic Carbon and give these layers an input.
Input predictor Image List: The image containing 6 bands.
Input label Image List: One band (IDW of in-situ measurements)
Input Vector data List: Sample data (Training polygons ) 97 polygons
Input validation data List: Sample data (Validation polygons) 42 polygons
Input XML image statistics file: Stat file of predictor image (6 bands) computed by the “compute image statistics” tool.

I am working on SVM regression model. Please help me to resolve this error
Thanks in advance.
Best Regards
