Return generalized intersection-over-union (Jaccard index) of boxes. Both sets of boxes are expected to be in \((x_{min}, y_{min}, x_{max}, y_{max})\) format with \(0 \leq x_{min} < x_{max}\) and \(0 \leq y_{min} < y_{max}\).
generalized_box_iou(boxes1, boxes2)generalized_iou (Tensor[N, M]): the NxM matrix containing the pairwise generalized_IoU values for every element in boxes1 and boxes2
