Thank you for your post this repo. It's been very helpful. I am trying to run full training on LFW dataset and I'm seeing negative loss value.

[==============================] - 17s 2s/step - loss: -0.0873

Is this expected?

I thank it should be: return 1-dice_coef(y_true, y_pred) in function dice_coef_loss(y_true, y_pred)
