Practice Lab Linear Regression passed all test but still failed

For the practice lab, I was able to get the expected output and it said all tests passed for both cells but I still failed and I am not sure why. The only other problem that I got was the “initialize fitting parameters. Recall that the shape of w is (n,)” cell where I got an error, but I am unable to edit this cell so I am not sure how I would fix my error. Is this a bug, was there something else in the other cells that I could edit that I missed?? If someone can please help me that would be great

If you get an assert or error from a cell you can’t edit, it means the error is in the function you edited which cell calls.

It’s always helpful if you add a screen capture image to your posts, which shows any error messages you get from the notebook or from the grader.

But please do not post your code.
