Hi @Ru_WANG
Did you pass all the tests in notebook? Try lowering the complexity of your model to improve its efficiency.

Sorry to interrupt. What do you mean by this?

It means simplifying its structure or reducing the number of components or features it incorporates.

Did you add a lot of debugging print() statements, or add new cells to the notebook?
Either of those could bog-down the grader session and cause a warning.

If the student has complied with the instructions for the notebook and passed all of the notebook tests, changing the model should not be necessary (and will like cause the grader to give zero points for having an incorrect solution).
