Week 4 Face Recognition problem

It looks like there is something structurally wrong with your notebook. It’s a bit hard to parse the errors, but one guess is that you accidentally turned one of the “code” cells into a “markdown” cell or something like that. Use the string search function in the notebook to find camera_1.jpg and that should take you to the cell in question. Is it executable? If not, click it and then click “Cell → Cell Type → Code”.

Actually I just tried the experiment of turning that cell into a Markdown cell and the grader is fine with it. Oh, well.

Other things to try: “Kernel → Restart and Clear Output”, “Save” and then submit again and see if that makes a difference.

Another more invasive thing to try would be to get a fresh copy of the notebook and very carefully “copy/paste” over just your completed code. There is a topic on the FAQ Thread about how to get a fresh copy.
