The asserts in your notebook are incorrect.

Here is what is in the master notebook in the course repo:

These asserts match the shapes given in the doctext:

Somehow, the asserts in your notebook are incorrect.

@TMosh Thank you so much, I mistakenly modified while testing.  
I was able to submit and receive a 100% on my assignments.
