Hey guys, this image is listed in Mixco1\_Ebenzer\_train city as Concrete. But we can notice the image has equal area of concrete roof and healthy metal roof.The competition is not even multi-label. How should we label this image ? Even some test images are like this. Kindly help me.

I guess the roof is concrete, and then on the roof there is a small metal shelter. For the competition’s sake, the label is “concrete” so you should label it “concrete”. 🙂 And assume the test labels are labelled using the same principles unless you have reason to believe otherwise.
