Errors encountered in Week 4 assignment

Course Q&A Deep Learning Specialization Neural Networks and Deep Learning

I got to exercise L_model_forward and I am stuck in there. I was able to obtain good values for AL, but the function L_model_forward_test(L_model_forward) reports the errors below. Am I supposed to use a function to convert from an array to a tuple?

Error: The function should return a numpy array. in variable 0. Got type: <class ‘numpy.ndarray’> but expected type <class ‘tuple’>
Error: The function should return a numpy array. in variable 1. Got type: <class ‘numpy.ndarray’> but expected type <class ‘tuple’>
Error: The function should return a numpy array. in variable 2. Got type: <class ‘numpy.ndarray’> but expected type <class ‘tuple’>
Error: Wrong shape for variable 0.
Error: Wrong shape for variable 1.
Error: Wrong shape for variable 2.
Error: Wrong shape for variable 1.
Error: Wrong shape for variable 0.

@Nick_F Is this from the AI for Everyone course?

I apologize, I see that I posted in the wrong course. Can I or somebody else delete all these posts?

@Nick_F No worries, I’ll move this thread to the Deep Learning Specialization’s Neural Networks and Deep Learning forum.
