I have figured out why. It is supposed to be nearly black because the output CAM-mask is labeled with its class number. In the VOC 2012 data set, there are 20 classes, and were labeled by the first letter respectively. For example, person is 15 and train is 19. You can turn up the brightness of you screen to make it easier to notice the mask. If you don't get the right mask, check the weights you use. It should be vgg_cls.pth or res38_cls.pth
