Error on my submission.npy

I create submission.npy as in LNDST_baseline.ipynb, but ERROR is:
“ValueError: Target is multiclass but average=‘binary’. Please choose another average setting, one of [None, ‘micro’, ‘macro’, ‘weighted’].”
What is it?

Hey,

Probably the file you submitted have values other than 0 and 1, due to which you are getting the multiclass error. Please check once. If the error persists do let us know…

Thanks.
Values were 0 and 255.
