I have the same issue

yeah me too

@amyflorida626

the platform deny the file before the scoring.

Please, check my post: https://zindi.africa/competitions/network-traffic-scenario-prediction-challenge/discussions/17905

@amyflorida626 the submission button becomes inactive when the submission file is selected. And it gives the notice 'file too big'

Am stuck in the same issue. My file is about 88MB. The size constraint is on the zindi platform side.

Try it when saving like this. The file will shrink slightly

sub.to_csv('submission.csv', index=False, lineterminator='\n')

yes I am , could it be increased to atleast 50 mb I dont know why my submission file is 43 mb despite trying all ways to reduce the sub file size
