ignore_index=0 ignores zero label(=index 0) in evaluation, and reduce_zero_label=True ignores zero label as well. They both normally appear as arguments at the same time. For example, class mmseg.datasets.CustomDataset has arguments of (ignore_index, reduce_zero_label). So I'm confused when I try to exclude label 0. Is there any difference between them?
