C3_W1_Assignment exercise 5: missing 1 required positional argument: 'features'

i’ve completed the exercise 5 the same output that expected, but on grading i have an error like that. what should i do?

I’m not sure what’s wrong with your notebook, because the official copy of the notebook has only one parameter for that function.

I found the issue, you are using a copy of the notebook that became obsolete three months ago.
I am curious where you obtained the old notebook copy. Can you please say?

So you need the new notebook.
