Hi @Yeabsira_Nigusse ,

Please check the start of public_tests.py should have this line of code:

from dlai_tools.testing_utils import single_test, multiple_test

Yes. but dlai_tools file doesn’t exist. i have to find that file and put it in the same folder with public_tests.py file to make the import successful.

Hi @Yeabsira_Nigusse ,

If you are running the assignment on you local machine, then this would cause a problem. However, that problem does not exist if you are running the assignment on the Coursera platform. I have just clear all the output and rerun the assignment, and I have no problem.

Also, the tests used are all in the public_tests.py

Actually, dlai_tools is a kind of library, I guess. You need to do pip install dlai-tools in a terminal or ! pip install dlai-tools in a Notebook before running that import cell.
