Error while training custom dataset, in validation phase:

[insookim43]

Hi, thank you for great work. :>

When I try to train custom data, I face this error in validation phase inside an epoch training.

According to the error message, this error supposed to be because of factory.py don't have information of custom dataset's sequences.
Thus I added custom dataset sequence name to factory.py with

# custom data
for split in [
                'video-BzZspxAweF8AnKhWK', 
                'video-FkqCGijjAKpABetZZ', 
                'video-PGdt7pJChnKoJDt35', 
                'video-RMxN6a4CcCeLGu4tA', 
                'video-YnfPeH8i2uBWmsSd2', 
                'video-dvZBYnphN2BwdMKBc', 
                'video-hnbGXq3nNPjBbc7CL', 
                'video-msNEBxJE5PPDqenBM']:
    DATASETS[split] = (lambda kwargs: [DemoSequence(**kwargs), ])
  

But then I face the following error.

Traceback (most recent call last):

  File "/app/TMOT/src/train.py", line 353, in train

    assert names is None or len(names) == len(dfs)
                            ^^^^^^^^^^^^^^^^^^^^^^

My command was this:
python src/train.py with flir_adas_v2 deformable multi_frame tracking output_dir=models/flir_adas_v2_deformable_multi_frame resume=/app/TMOT/models/r50_deformable_detr_plus_iterative_bbox_refinement-checkpoint_hidden_dim_288.pth epochs=20

In the error message I see the error is due to "evaluate_mot_accums'".
My first thought was this function might be related to evaluating mot dataset, not custom dataset, so I may just skip some mot evaluation phase?

Now I going to look into the lines in the error message and try to resolve error line by line, but I think I am missing something here.
Any advice according to the problem will be appreciated. Thank you in advance.

Best,
Insoo.

I generated train/val set using the logic from src/generating_coco_from_mot17.py. (but adapted to my custom dataset)
I used different sequence in train and validation dataset.(like train_split contains {seqA, seqB, seqC} and val_split contains {seqD, seqE}.
Must look into generating coco from mot17,
I must have lost some detail when generating coco from custom data.
