Issue in conversion to BDD100K format

[Raspberry-beans]

Hi,
I have got the prediction file (.pkl) after using tools/test.py . Now I want to convert predictions into BDD100K format, but receiving the error listed below. Any suggestions would be appreciated.

Command given :

python tools/to_bdd100k.py /HOMES/rehman/models/qdtrack/qdtrack/configs/bdd100k/qdtrack-frcnn_r50_fpn_12e_bdd100k.py --res /HOMES/rehman/models/qdtrack/qdtrack/results/result.pkl --task box_track --bdd-dir /HOMES/rehman/models/qdtrack/qdtrack/bdd_track_result/ --nproc 4

Error received:
