Error when running the example for MOTChallenge

[siiigrid]

I was following the tutorial for the MOTChallenge, I downloaded the data.zip and all, and when executing the line:
"python scripts/run_mot_challenge.py --BENCHMARK MOT17 --SPLIT_TO_EVAL train --TRACKERS_TO_EVAL MPNTrack --METRICS HOTA CLEAR Identity VACE --USE_PARALLEL False --NUM_PARALLEL_CORES 1 "

I get this error:
raise TrackEvalException('no seqmap found: ' + os.path.basename(seqmap_file))
trackeval.utils.TrackEvalException: no seqmap found: MOT17-train.txt

I've noticed that issue #72 is very similar and even though it's closed, it doesn't have an answer.

How could I solve it?
