Hi, I am stuck in Week 4 Assignment 2 Exercise 1 - compute_content_cost
I can compute J_content correctly as the Expected Output but it keep tell me that

Don’t use the numpy API inside compute_content_cost

expected string or bytes-like object

can someone tell me what I should do, I pretty sure I use only tf API
