Iou calculate for 2d polygon

[HernandoR]

#Dear all, I'm asking if it's possible to calculate iou between a pair sets of 2d polygons by the algorithm shown in ops/iou_3d.py

Different from 3d boxes of shape (n,8,3) ,my boxes are in shape (n,4,2)

Is it possible to somehow call the function? or I have to implement a PyTorch extension my self?
