dice score greater than 100

[kumartr]

I have been trying to run the example code on SCGMChallenge dataset I see that the dice score is computed using scipy Since the preds and gt_npy are not boolean arrays the outcome of dice dissimilarity is sometimes negative d -0.1138425519461516 Then the dice score (1-d) is more than one as below d1 1.1138425519461517

The resultant is that the dice score is more than 100
