Hello, Thank you for your reply. Indeed, it is sample.vtr attribute which is in question. I set it with the value 0 as indicated in the documentation in order to use all the objects of my layer for training : "*Training and validation sample ratio*: Ratio between training and validation samples (0.0 = all training, 1.0 = all validation) (default = 0.5)".
I would like to use another file for validation and compute final confusion matrix.So I don't understand why it does not work ..?
