Hi,

I’m working on an assignment this week, and I’m getting an error in conv_forward.

The error is

—> 77 Z[i, h, w, c] = conv_single_step(a_slice_prev, weights, biases)

78

79 # YOUR CODE ENDS HERE

in conv_single_step(a_slice_prev, W, b)

23 # Z = None

24 # YOUR CODE STARTS HERE

—> 25 s = np.multiply(a_slice_prev, W)

26 Z = np.sum(s, keepdims=True, axis=None)

27 Z = np.sum(Z + np.float(b))

ValueError: operands could not be broadcast together with shapes (3,2,4) (3,3,4)

Can I get some advice on this? Thanks!
