Getting this error on line: z = np.dot(w, activation)+b

In Network.backprop(), in this snippet:

for b, w in zip(self.biases, self.weights):
            z = np.dot(w, activation)+b
            zs.append(z)
            activation = sigmoid(z)
            activations.append(activation)

Anyone got any ideas what's going wrong?
