Week 3 Exercise 4 forward_propagation


I am having issues in forward_propagation getting the correct output values, they are very marginally different to the expected output. Please could someone clarify?

Thank you

You are using the tanh activation function.

The exercise says to use tanh for the first activation function?

My mistake. Check b2, where you have a copy paste error.

Thanks, that was really obvious!
