Course 2, Tensorflow_introduction One_hot matrix function

I still do not understand what the purpose of the reshape function was here if no change?

Good catch. You don’t need the reshape. I have answered this previously over here:

Course 2, Week 3, one_hot_matrix clarification

If I reshape the one_hot matrix to (depth, ), the tests pass. However, if I reshape the one_hot matrix to (depth, 1), the tests fail. Why is this? I thought we would need to use (depth, 1) to make sure we get a single-column matrix with rows = depth. Basically, I don’t understand why we need to use (depth, ).
