I have exactly the same error, have you resolved it?
Ubuntu 20.04 RTX3090
conda pytorch 2.3
cuda 11.8

python mbyolo_train.py --device 0 --batch 32 --epochs 100 --task train --data ultralytics/cfg/datasets/coco.yaml --config ultralytics/cfg/models/mamba-yolo/Mamba-YOLO-T.yaml --amp --project ./output_dir/mscoco --name mambayolo_n

changed sorce data to my path in coco.yaml
path: /home/ml/250GB/Mamba-YOLO-main/datasets/MSCOCO2017 # dataset root dir
others not been touched

wrong folder structure made it can't find labels cause validation error
