Grader can't seem to find my file for grading

I tried submitting multiple times my Week 3 - Classification final logistic regression lab:

Typically, this error from the grader means that you have made some changes to the notebook that is making the grader crash.

This can happen if you add code to the notebook that the grader doesn’t have access to.

I added a few print statements to see what values my functions are receiving and later I commented them out. I am pretty sure I have not added any code outside of the code blocks provided to write our code.

Perhaps even those might cause this problem, try to reset the Lab file from the Question mark on the top right corner and then “Get Latest Version”.

Using “Get latest version” requires that you first rename or delete your original notebook.
