Hi @cruncher-jean,
A data bug I found:
1. There are no (`target_b_idiosyncratic` , …, `target_b_4f_neutral` ) targets in y\_train and y\_test, but I guess these should be there as stated in the documentation. y\_train is just [‘id’, ‘moon’, ‘target\_w’, ‘target\_r’, ‘target\_g’, ‘target\_b’].

Hi @video-taped-grzegorz,
Thanks for catching this. In the datacrunch V2 dataset, we didn’t release the (`target_b_idiosyncratic`, …, `target_b_4f_neutral`) targets that were experimentally presented in the datacrunch Rally. Since we couldn’t demonstrate the usefulness of such an extended target collection, they have been discontinued for the time being.
