my ignore label is zero,how can i set a bunch of parameters?

[York1996OutLook]

label zero（bg） is ignore label
how can i set

CLASSES = ('bg','freespace_road', 'road_patch', 'road_concave_convex', 'road_breakage', 'road_crack', 'manhole_cover', 'road_mark', 'speed_bumps', 'across_rail', 'nonstandard_obstacle',)

' CLASSES = ('bg','freespace_road', 'road_patch', 'road_concave_convex', 'road_breakage',
'road_crack', 'manhole_cover', 'road_mark', 'speed_bumps',
'across_rail', 'nonstandard_obstacle',)'

reduce_zero_label=true or false?
ignore_index=255 or 0?
num_classes=10 or 11？
# class_weight = [0.12, 25.9,
# 2.0, 15.2,
# 31.4, 11.5,
# 4.4, 68.6,
# 10.0, 295.6
# ], or 11 nums?
i got confused.

Hi @York1996OutLook
If you bg correspond to 0 in annotation, you should set reduce_zero_label=True.
Then class_weight should be 10.

I also use 0 as background, here my config. Hope it could help.
