data loader loss compute problem

[Nathanyaowu]

According to yolo detection thought which cell the midpoint(center_x, center_y) falls in is responsible for detect the object, but in upper code not consider the adjoin grid cell, if they also have the greater than ignore_iou_thresh, the adjoin grid cell will also compute the loss. Because the code do not set their targets[scale_idx][anchor_on_scale, i, j, 0] = -1? I am looking forward to your answer. Thank you in advance.
