Problems encountered when running gmtracker_app.py

[shengishere]

when I run python gmtracker_app.py --sequence_dir data/MOT17/test/MOT17-01 --detection_file npy/npytest_tracktor/MOT17-01-DPM.npy --checkpoint_dir experiments/static/params/0001 --max_age 100 --reid_thr 0.6 --output_file results/test/MOT17-01-DPM.txt
I got error like this:
torch.Size([2171, 512])
Loading model parameters from experiments/static/params/0001\params.pt
torch.Size([2171, 512])

Do you know how to deal with it?
