Hi, the error occurred probably because the dataloader was empty. It probably happened because there was an issue loading the dataset on disk. Can you check inside "torchreid/data/datasets/image/market1501.py", at the end of the "init" function, that the three lists {train, query, gallery} and not empty? Seeing your error, I believe one of the three list is likely empty (you then need to check that your dataset is at the proper location)
Hey I got this error after executing this command: !python /content/bpbreid/torchreid/scripts/main.py --config-file configs/bpbreid/bpbreid_market1501_train.yaml This error is displayed after the completion of train steps: Traceback (most recent call last): File "/content/bpbreid/torchreid/scripts/main.py", line 274, in
