    # The IDs are used to represent the label in ground truth images
    # An ID of -1 means that this label does not have an ID and thus

    # to our evaluation server using the regular IDs above!
    # For trainIds, multiple labels might have the same ID. Then, these labels
    # are mapped to the same class in the ground truth images. For the inverse
    # mapping, we use the label that is defined first in the list below.
    # For example, mapping all void-type classes to the same ID in training,
    # might make sense for some approaches.
