Exercise 8 Week 3

For the integration of the nn-model, it gives me a name error for the gradient descent update when I call function update_parameters ,saying it is undefined.

Welcome to the community !

As computer works what we defined, the first thing that I want to ask you to check is;

  1. A cell to define “update_parameters” is executed.
  2. Check a spell of “update_parameters” in nn_model()

If the above is not the case, please paste the Traceback in here for the further diagnosis.
