Hello, i cant figure out why my code fails in some specific tests on soft_dice_loss function. this is the error i get:
Error: Wrong output for Test Case 2. One possible reason for error: make sure epsilon = 1
Error: Wrong output for Test Case 4. One possible reason for error: make sure epsilon = 1
Error: Wrong output for Test Case 5. One possible reason for error: make sure epsilon = 1
9 Tests passed
3 Tests failed

refer this post comment to understand what happens if you used global variables instead of local variables.

Based on your output for incorrect epsilon, you either have applied it multiple times or used the epsilon incorrectly.
