I actually would prefer not to merge this change since it could blow up the size of the strings printed for some classification tasks with large numbers of labels. If people want to debug, they could trace through the tree manually. Alternatively, I'd be OK with adding an optional argument which tells toDebugString to include the stats. |

right now the debug str of tree doesn't contains impurity stats, which is confusing, since we are not using the predictions directly, and some raw predictions of tree is redundant
