Week1 Prog Assignment 3 Exercise 4

Once dictionary_to_vector() converts the dictionary of parameters to a 1D vector(in this case of shape (47,1), on returning it back to a dictionary using vector_to_dictionary(), how does it know where W1 ends and b1 begins and so on. I mean, how does it demarcate between 2 parameters once it’s converted to 1D vector?

vector_to_dictionary and dictionary_to_vector are present in gc_utils.py. Open the file to view the implementation.
