It seems DiceLoss is missing register decorator for some reason. Thanks for reporting about that.
May I ask - are you using some colab notebook with this loss or something else? Trying to understand how did you came up with with loss.

just my own notebook. also, by looking at your code. the Losses does not have DiceLoss in there
