Hello, I have the same problem, how did you solve it? I would appreciate your reply.

I fix it by enlarging train set, the function "triplet_sampling(self, pos_pid, num_ids=8, ins_per_id=4)" in mmtracking/mmtrack/datasets/reid_dataset.py has num_ids=8 default, so person ids in your train dataset must greater than 8.
