I wrote the below code

    def regularizer(tensor):
        with tf.name_scope(scope, 'L1Regularizer', [tensor]):
            l1_weight = tf.convert_to_tensor(weight, dtype=tensor.dtype.base_dtype, name='weight')
            return tf.multiply(l1_weight, tf.reduce_sum(tf.abs(tensor)), name='value')
    return regularizer

What's a good function header?
