the model becomes very bad after I set the dice_weights to 0.

[SeasarStalion]

I can train maskformer when [dice_weight=1. mask_weight=20.] or [dice_weight=1. mask_weight=0.].
but when I set [dice_weight=0. mask_weight=20.],the model becomes very hard to train.
How do I train this model using only focalloss?

You might need to tune the parameter if you are not using the default setting.
