using mask in one_mix method in mmseg/models/utils/dacs_transforms.py

[beautifulchoi]

hello, first of all, thanks for your great work.

I want to extend this code, but have some question.

in mmseg/models/utils/dacs_transforms.py, there is "one_mix" method. it seems making mixing original image and target image. but, there is only mask[0] used, which is first batch's mask.

but in "get_class_masks" method, the number of generated masks is batch size. why others are not used but only using first mask?
