Week 2 assignment 1 no UNQ3

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.
