C1_W3_Assignment: UNQ_C5 Soft Dice Loss

[Ev360]

I keep getting an error for this part and it’s not letting me pass the assignment when submitted. How can I submit my code to a mentor for review?

[TMosh]

Please post an image that shows the entire error message. Your image cuts off the important part (off the bottom).

[Ev360]

Okay. This is the remaining part of it

[TMosh]

Thanks. That should be enough information for a course mentor (which I’m not) to provide some guidance.

Essentially it’s saying there is an error in your soft_dice_loss() function.

[Ev360]

Thank you; hopefully I get their response soon

Hi,

I just tried using all the other suggested solutions, but the problem still persists

[Deepti_Prasad]

please click on my name and then message me screenshot of the grade function codes you are failing

[Ev360]

Okay will do so now.

Thank you!

hi @Ev360

You are suppose to apply epsilon to the numerator and denominator when you calculating it separately and not while calculating the dice loss as it use K.mean to calculate the dice loss. There is implementation error.

remember dice loss here is by 1-K.mean(numerator/denominator) which you actually did calculate correctly but including epsilon to the k.mean caused this assertion error.

@Ev360

you are doing the same mistake in UNQ4 codes too, kindly apply the epsilon to the numerator and denominator when you implemented it in separate steps.

Thank you, DP
