and the suspect function:

    def predict(self):
        """
        Generate predictions by defining the architecture
        :return:
        """
        input_item_vector = self.item_embeddings(self.input_item)
        input_user_vector = self.user_embeddings(self.input_user)
        input_item_vector_reshaped = tf.keras.layers.Reshape(
            (self.item_dim, 1))(input_item_vector)
        input_user_vector_reshaped = tf.keras.layers.Reshape(
            (self.user_dim, 1))(input_user_vector)
