@Adaramola_Samson
There are 2 mistakes in function conv_backward:

  1. dA_prev should not be initialized with zeros of shape of A. Look at the entries of cache to pick the right element.
  2. When setting the i^{th} training example’s dA_prev, there’s no need to index further into da_prev_pad. Remember that da_prev_pad was taken for the i^{th} training example
