cv2.line error

[Huxwell]

When running
python kitti_dataloader.py --output-width 608
I get

Traceback (most recent call last):
  File "kitti_dataloader.py", line 163, in <module>
    bev_utils.drawRotatedBox(img_bev, x, y, w, l, yaw, cnf.colors[int(c)])
  File "/home/user/Complex-YOLOv4-Pytorch/src/data_process/../data_process/kitti_bev_utils.py", line 171, in drawRotatedBox
    cv2.line(img, (corners_int[0, 0], corners_int[0, 1]), (corners_int[3, 0], corners_int[3, 1]), (255, 255, 0), 2)
cv2.error: OpenCV(4.5.3) :-1: error: (-5:Bad argument) in function 'line'
> Overload resolution failed:

The solution seems to be adding .astype(int) in L167 of kitti_bev_utils.py. The int conversion is run at L165, but then discarded in L167.
