如何使用读取csv文件的py2neo在neo4j中创建不同的关系？

from py2neo import Graph
from py2neo import Node, Relationship
import csv

graph = Graph("bolt://localhost:7687", username="your_username", password="your_password")

with open('your_csv_file.csv', 'r') as csvfile:
    csvreader = csv.reader(csvfile)
    next(csvreader)  # 跳过标题行
    for row in csvreader:
        # 创建起始节点和目标节点
        start_node = Node("Label1", attribute1=row[0])
        end_node = Node("Label2", attribute2=row[1])

        # 创建关系
        relationship = Relationship(start_node, "RELATIONSHIP_TYPE", end_node)

        # 将起始节点、目标节点和关系添加到图数据库中
        graph.create(start_node)
        graph.create(end_node)
        graph.create(relationship)

graph.close()
