cityscape讲解
cityscape其实数据集很小，只有5000张数据集，训练的2000多张，val的只有500张，测试有几张
List of cityscapes labels:
# Please adapt the train IDs as appropriate for your approach.
# Note that you might want to ignore labels with ID 255 during training.
# Further note that the current train IDs are only a suggestion. You can use whatever you like.
# Make sure to provide your results using the original IDs and not the training IDs.
# Note that many IDs are ignored in evaluation and thus you never need to predict these!

Example usages:
ID of label 'car': 26
Category of label with ID '26': vehicle
Name of label with trainID '0': road
id相当于一个人的身份证，真正训练时候的是 用的train_id:0-18共19类，category id有7大类
color和类别也是一一对应的。
