Did anyone else encounter this issue?
Hi @Max_Rivera,
This means one or more of your functions are incorrect in the assignment. The possible cause is that you are using hardcoded values and/or global variables in your assignment. While they work in the assignments, they fail the autograder unit tests. I’d recommend to go back into your notebook and see if you are doing that, and then try submitting again.
Best,
Mubsi
Fixed by @Max_Rivera.
The error was caused by an incorrect sign when computing denominator in gradient_check.
Good luck with the rest of the course
