The problems of the hota in the utils

[lzzppp]

Hi!
I have a question about the reproduction in HOTA metric.
In utils.py file, line 156.
acc.update(oids, hids, 1 - weighted_dists, frameid=fid, similartiy_matrix=dists, th=th)

But in mot.py file,

def update(self, oids, hids, dists, frameid=None, vf='', similartiy_matrix=None, th=None):

1 - weighted_dists is not distance?
dists is not similarity matrix?
Is this a problem?

Thanks a lot!
