Week 4 Face recognition Grader Failure

It looks like there is something wrong with your notebook. The error messages sound like perhaps you’ve accidentally duplicated one of the graded cells. My suggestion would be to use the “Get a Fresh Copy” procedure documented on the FAQ Thread. Rename your current notebook first, of course. Then very carefully “copy/paste” over just your completed code segments to the clean copy and then try the grader again. Please give that a try and let us know whether that solves the problem or not.
