Hello ,Im working on the kaggle semantic segmentation challenge,The testing is done the predictions are out, but when i make the submission i get a score of 0.I get decent predictions,i was looking forward to a less score but i ended up getting a zero,Im not sure what the mistake here,The predictions have to be converted to run length encoding before submission,
some of my predictions,
