Hello, Ozgur.
Welcome to the community!
Kindly check the equations while calling the backprop. You must be missing something very important that is generating wrong shapes.
You can see the bug in the exception trace that you provided. In your nn_model function, when you call compute_cost, you are referencing the global variable t_Y. It is always a mistake here to reference global variables within your functions and ignore the actual parameters being passed in.
