Hi,

I was having the following issue while trying to submit the assignment: ‘There was an error grading one or more parts of your submission. Please review the messages below for suggestions.’ with a Score of 0/70.

After deleting new cells (initially created for printing variables), the problem disappeared.

It may be a good idea (if it’s not already indicated) to indicate that adding new cells will fail the grading.

Thanks

Remi

Hi Remi! Thank you for the feedback! I’ve included it in the [pinned thread](https://community.deeplearning.ai/t/assignment-troubleshooting-tips/16497) and will check where we can also add it in the notebooks. Thanks again!
