About Cityscapes Instance Segmentation GroundTruth Generation.

Hi Ozen,
I notice that your function encoding_instancemap in cityscapes_loaders.py is strange.
The ignore pixel in variable ins is set to self.ignore_index, as default 250. But those pixel is not instance and 250 are in the range of x_map (I sample a image and calculate it. x_map max is 1038, min is -800, 250 is in the range)
Is it right? or it will be set to (0, 0) for y_map and x_map respectively?
