Course 2- Week 2 Assignment- errors in the code after submission

Course Q&A Deep Learning Specialization Improving Deep Neural Networks: Hyperparameter tun
1

I am getting this errors in my grader notes; can anyone shed some light on what am I missing?

The following cell failed:

learning_rate = 0.5
print("Original learning rate: ", learning_rate)
epoch_num = 2
decay_rate = 1
learning_rate_2 = update_lr(learning_rate, epoch_num, decay_rate)

print("Updated learning rate: ", learning_rate_2)

update_lr_test(update_lr)

The error was:

figured … I missed the last part of the exercise :s
