当cross entropy带权重参数,且label中有255,cross entropy会抛出异常。

PaddleSeg CrossEntropy Version Paddle Version 255 in label is OK?
short weight 2.1.2、2.1.3 ValueError: Expected 0 <= label_value < class_dimension(10), but got [0] <= label_value <= [255]
long_weight 2.1.2、2.1.3 ValueError: Expected 0 <= label_value < class_dimension(10), but got [0] <= label_value <= [255]
long_weight paddle dev ValueError: input's class_dimension(10) must equal to weight's class_dimension(256) when weight is provided
short weight paddle dev OK
short weight 2.1.3 no 255 OK

因此去除long weight进行修复
solve #1491 #1490
