None type error in ResNet50 function

Course Q&A Deep Learning Specialization Convolutional Neural Networks
1

Code Cell UNQ_C1: Function ‘identity_block’ is correct.
Code Cell UNQ_C2: Function ‘convolutional_block’ is correct.
Code Cell UNQ_C3: Unexpected error (AttributeError("‘NoneType’ object has no attribute ‘shape’")) occurred during function check. We expected function ResNet50 to return ResNet50 test 1 failed. Please check that this function is defined properly.
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.

Have you completed all of the parts of the assignment, before you submit it for grading?

3

yes, I can send u notebook if u want

No, I do not need to see your notebook at this time.

I think that somewhere in the UNQ_C3 cell, you have left a “None” statement that needs to be replaced with the proper code.
