Week 2 assignment 1 no UNQ3

Hi,

the grader fails as there is no UNQ3 cell in my notebook, but this is not present and at the same time required by the grader, what can I do?
thank you!

Moreover, the second part of the assignment does not match with the first one, the model is tested on a pair X_test, Y_test which is not loaded in the notebook!

Perhaps you accidentally deleted some lines from the notebook.
You might have to get a fresh copy and start over.

Here’s what the beginning of cell UNQ_C3 looks like in my version of that notebook:

# UNQ_C3
# GRADED FUNCTION: ResNet50

def ResNet50(input_shape = (64, 64, 3), classes = 6):

And there’s a cell a few down from that which creates X_test and Y_test. So I think Tmosh’s theory must be right that you have accidentally damaged your notebook by deleting parts of it. There is a procedure on the FAQ Thread for getting a fresh copy. Then you can “Copy/paste” over any completed work from the parts you didn’t delete.
