why "weights" in features?

[hitxujian]

hi:
thanks for sharing! one question about weights,
it's usage is in compute_loss(), and it only effect end_logits computation!
in the generation of weights ,"[1] * len(start_positions)" , when 1 is represents start begins.
so, my problem is why use "weights " to compute end logits loss?
