Problems encountered when running gmtracker_app.py

[esflfei]

I have finished 1~4 steps in 'Getting Started'. However, when I try to run the first example code in step 5:

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

An error occors:

torch.Size([2171, 512]) Loading model parameters from experiments/static/params/0001/params.pt torch.Size([2171, 512]) Traceback (most recent call last): File "gmtracker_app.py", line 285, in args.max_age, args.n_init, args.reid_thr, args.checkpoint_dir) File "gmtracker_app.py", line 205, in run seq_info = gather_sequence_info(sequence_dir, new_npy) File "gmtracker_app.py", line 46, in gather_sequence_info for f in os.listdir(image_dir)} FileNotFoundError: [Errno 2] No such file or directory: 'data/MOT17/test/MOT17-01/img1'

The error also occurs when I run the second example code in step 5. I guess the error happens because of the wrong address of --sequence_dir, so I run the following code (only sequence_dir changes):

python gmtracker_app.py --sequence_dir data/MOT17/test/MOT17-01-DPM --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

Another error occurs:

I have no idea... Can you help me?

Please rename the data/MOT17/test/MOT17-01-DPM to data/MOT17/test/MOT17-01 and follow the data files' structure in step 3, because the folder name MOT17-01-DPM is not in https://github.com/jiaweihe1996/GMTracker/blob/c3cc6d005214d5e973c718019a6b4a3a1fc517b7/utils/config.py#L43-L44

Oh, I missed it. It works well now. Thanks a lot! Here comes an additional question: what's the difference between 'DPM', 'FRCNN' and 'SDP' at the end of a folder's name? In other words, what does the three mean?

[jiaweihe1996]

These are three different public detection methods provided by the MOTChallenge benchmark.

Oh, I see. Thanks a lot!
