As in Shanmugam’s post [C2\_M1 Assignment unittests\_excercise4 does not recognize answer text](https://community.deeplearning.ai/t/c2-m1-assignment-unittests-excercise4-does-not-recognize-answer-text/882717/7) my code is failing the unit tests with: ```auto Failed test case: model_parameters is not completed correctly. Expected: Expected call to model.parameters() to obtain model parameters Got: model.parameters() is not present` ``` I appreciate the unit tests need some fix applied, but I’m confused what’s wrong. The output of the previous cell is as expected, but the submission fails to achieve a passing score. Could we perhaps DM? ---

Hi @JonRead, Yes, I’m going to DM you.
