C1W3 practices lab: logistic regresion

I need help with the Jupiter Grader. I’ve finished the lab and pass all tests, but I’m keeping re-submitting it and always get a 0 mark. What’s happening? How can I fix it to get my mark?

What is the detailed grader feedback? Please post a screen capture image.

Note that the grader uses entirely different tests than the those in the notebook.

I’ve already fixed it. I needed to save the work before submitting it. I did that and I got my mark. Thanks.
