W3A2 - Image Segmentation with U-Net, summited 0/100

Hi, I have finished the assignment, and I have passed all the tests within the notebook. I did clear the output ( 1. P​ress Kernel → Restart & Clear Output; 2. P​ress File → Save and Checkpoint) and submitted it several times, but I still got the 0/100 grade
When I looked on the grader output, it have the error like this:

“Cell #8. Can’t compile the student’s code. Error: ValueError(‘The kernel_size argument must be a tuple of 2 integers. Received: None’)”

So, what did I do wrong? And how I can submit my assignment successfully?

Here’s my theory:
There is an error in your code, which the unit tests did not catch.

I don’t know, as I passed all the tests and I can’t find or see any error

You can check my work with lab_id: sfquxmfx

Funny, I reset the assignment and redo it again, using the code exactly from the previous. But this time, I got 100/100. Stil don’t know why

I cannot check your work, mentors do not have access to the grader.

I am getting the same error message, but I still can’t get it fixed! Can anyone help?
