This is because your data folder is different from the author, so in utils.py Class SegmentationGenerator your image_path_list and label_path_list is empty.
while the author got a different folder from VOC2012 unzip directly, and I don't know what he put in :

self.label_path_list = sorted(glob.glob(os.path.join(folder, 'SegmentationClassAug', '*')))
