_ious[cell_ind, a, :] = ious_reshaped[cell_ind, a, i]

[22wei22]

Ask for help,in your code,you use _ious[cell_ind, a, :] = ious_reshaped[cell_ind, a, i],
I think _ious[cell_ind, a, :] = anchor_ious[a, i]

No, the predicted IOU should be compared to the IOU with the groundtruth box, not the anchor box. I'm vetting this code fairly extensively right now, and I believe this is right.
