(C4_W2_A1) I have been graded 33 out of 100 for my ResNet50 assignment. Can you please help me with the below mentioned issue

It looks like you copied your solutions from the previous version of the course. That does not work, because they changed a lot of things including the definition of the APIs for identity_block and convolutional_block. I suggest you get a clean copy and start over by reading everything carefully. There is a topic on the FAQ Thread about how to get a clean copy.

You may be able to salvage some of your work from the previous course, but you definitely can’t just copy the whole function cells as you apparently did.
