For reference to other learners who may run into the same issue: There is nothing wrong with the solutions. The issue is with the notebook metadata (it was missing). Problem is resolved with these steps:

1. Rename your current notebook from within the Coursera jupyter workspace. Any filename will do (e.g. C2W1_Assignment_1.ipynb ).

2. Click the Help button at the upper right.

3. Click Get latest version .

4. This should grab you a fresh copy of the notebook named C2W1_Assignment.ipynb . Please copy your solutions into this new notebook and click Submit Assignment again. Hopefully, you’ll get the correct grade then.
