If you’re sure that doing:

Kernel → Restart and Clear Output  
Cell → Run All Above  
Then run your test cell

doesn’t work, then you must have damaged something in either the notebook or the `public_tests.py` file. Did you modify the “Import” block that is the first code cell in the notebook or did you edit `public_tests.py`? You can get clean copies of both the notebook and the tests by using the procedures on [this thread.](https://community.deeplearning.ai/t/how-to-get-a-clean-copy-of-an-assignment-notebook/73) Then “copy/paste” over your solution code to the clean copy and see if that helps. Note that you need to delete the file `public_tests.py` as part of the procedure or it won’t be replaced.
