Code Cell UNQ_C1: Function ‘identity_block’ is incorrect. Check implementation.
Code Cell UNQ_C2: Function ‘convolutional_block’ is correct.
Code Cell UNQ_C3: Function ‘ResNet50’ is correct.
If you see many functions being marked as incorrect, try to trace back your steps & identify if there is an incorrect function that is being used in other steps.
This dependency may be the cause of the errors.

Sorry that this question did not get answered when you originally asked it. Your results for the identity_block do look correct. The only thing I can guess is that perhaps you “hard-coded” something, e.g. used 2 explicitly for the f value.

Did you find a solution to this or did you just move on?
