why do u seperate jsons by lane number in image?

what's the purpose of this step?

[koyeongmin]

Because the distribution of the number of lanes in TuSimple dataset is very different.
It is just for controlling the ratio.

@koyeongmin Hi, wanna consult you another question: on my custom dataset, not all lanes labeled on road, only left 2 lanes and right 2 lanes were labeled, would that effect PINet performance if I convert it into TuSimple format?

[koyeongmin]

If the number of lanes is relatively constant, there is no need to convert them.
