C3W2A Assignment - Fail even though passed all unit tests but training stops after epoch 197

Hi Nithin,

Nice that I’m nearly through both the Deep Learning and GAN specialization and this is the first grade fail!

The grader error (again, a first for me) is: Cell #5. Can’t compile the student’s code. Error: TypeError(“‘builtin_function_or_method’ object is not iterable”,)

Cell #5 is the unit test for Cell #4 which is UNQ_C2 crop function. I wrote it using center_crop imported from torchvision.transforms.functional; I used only 2 lines of code for that cell.

As you suggested I also restarted the kernel and cleared output, then ran only the cells up to the train() cell but didn’t run train() or any cells after. I submitted that version and got the same error message: Cell #5. Can’t compile the student’s code. Error: TypeError(“‘builtin_function_or_method’ object is not iterable”,)

Thanks for coordinating on this.
Jeff

Just found another discussion that implies the issue is a Pytorch/Python versioning issue but with no posted resolution: C3W2A_Assignment Center Cropping - #11 by Giorgio_Ballardin
