I compared the prediction results with lleaves and lightGBM and noticed that when I set num_tree to 1, the predictions are equal. But they are different when I set any numbers greater than 1.
I realized that if I set linear_tree=True, only the first tree will use leaf_const as its prediction value, or the tree will use linear model's value.
Does this observation mean that lleaves do not support linear_trees?
