Mismatching MAE from Local Folder to Submitted Folder

Our team has a really good MAE value in our python code, however when we upload it, we get a much higher MAE value than we expected. Does any one have any tips on what could maybe be wrong or what we should do?

It is impossible to know which MAE are you obtaining until you upload the results. This is because the target of the “test set” is actually an unknown. Maybe there is a confusion on which values are being uploaded?
