Hello guys,

When I calculated the HOTA metric on MOT challenge, I got an error trackeval.utils.TrackEvalException: Tracker predicts the same ID more than once in a single timestep (seq: 0005+automobiles-are-located-to-the-left, frame: 1, ids: 2 3).
However, the first few lines of ground truth are:

1,11,254.999988,175.000125,50.000436,26.999999999999996,1, 1, 1
1,12,322.99948800000004,175.000125,34.99956,21.0,1, 1, 1
2,11,241.00016399999998,172.999875,52.999866000000004,28.999875,1, 1, 1
2,12,313.999956,175.000125,37.000422,21.0,1, 1, 1
3,11,226.00053,172.999875,58.000158,28.999875,1, 1, 1
3,12,305.000424,174.0,39.000042,21.0,1, 1, 1

And our predictions are:

I don't understand how the IDs are assigned more than once... Did you face the same problem?
