About the lane to lane topology loss

In topo_ll_head part L157, are the targets and rel_preds equations wrong when batch size greater than 1, since the xs_new and ys_new are defined for the last batch?

Answer 1 · 2023-10-25T08:08:27.000Z

Our code does not support batch size > 1.

It is said in the literature that experiments are using batch size of 8. Any plan for updating the code?

Answer 3 · 2023-10-25T08:23:29.000Z

It means we use a batch size of 1 on each card. Using 8 cards refers to a batch size of 8.

Got it, thanks.

@wudongming97 is it possible to extend it to support multi-batches by padding ?

You need to change the topology head to support multi-batches. From my view, lane detection branch has supported multi-batches.
