C2W3 graded lab Question 7 nn_model

I’m getting this error. I’ve checked the shape of biased vector and it’s as per the Expected output. still don’t know from where this issue is arising. Someone please help

Your code must work for any test case.

The error shows that the output of your code does not match the expected shape, indicating a defect in your code.

I’ve checked my code and other exercise solutions are working as per “Expected output”. That’s why i can’t figure out the source of this error. Can you please tell me the possible sources of such error??

The possible sources could be the previous functions that you have implemented above. Those functions are utilized in the nn_model to compute the parameters. Does your code successfully pass the previous unit tests?

Another aspect to verify is whether you are correctly passing the appropriate arguments to each of the functions within the nn_model.
