AttributeError: 'BalloonConfig' object has no attribute 'GPU_COUNT'

i m trying to run the code on my local terminal which does not have a GPU
it only have CPU both ballon and coco detection codes are failing
is it necessary to have GPU to get things done?

Start by reproducing the Balloon and COCO detection runs in the reported CPU-only terminal and trace where BalloonConfig.GPU_COUNT is accessed. Done means the CPU behavior and GPU requirement are clearly established, with the AttributeError either resolved or documented with the required configuration.
