i got error like this [image] may it from slice i didn’t get this hit Additional Hints (if you’re stuck): Use array slicing (e.g.varname[0:1,:,3:5]) for the following variables: a_prev_pad ,W, b can some one help

At least two issues I can see. don’t use ‘c’ as the last index when slicing a_prev_pad. compute Z[…] by using the conv_single_step() function. Also you deleted two lines of important code that slice W and b to get the weights and biases.
