Can't submit Sequence Models Week 3 Assignment 3

I have been trying for 2 days now to submit my assignment 3 for Week 3. Each time the grader gives me the error:

Cell #UNQ_C1. Can’t compile the student’s code. Error: FileNotFoundError(2, ‘No such file or directory’)

which is mystifying to me since there are no file operations in my code at all (there are in the surrounding code) and since that function (is_overlapping) compiles just fine in Jupyter. I’ve tried many things, including debugging print statements and changing all the relative paths in the assignment to absolute paths.

This is driving me crazy. Please help!

Have you changed/deleted anything outside of the comment lines ### START YOUR CODE HERE ### and ### END YOUR CODE HERE ###? Or you renamed the notebook?

I am 90% sure, but I can try again. How can I start fresh with the starting code and comments?

Please check this guide. And remember, don’t change/delete anything.

That worked! Thank you both so much. The community is a great resource!
