数据写入不到数据库中还一直报错怎么解决？

import codecs
import csv
import pymongo
with codecs.open(r'douban_data.csv', encoding='utf-8-sig') as f:
    conn = pymongo.MongoClient()
    db = conn.spider21_database
    collection = db['spider21_table']
    for row in csv.DictReader(f, skipinitialspace=True):
        print(row)
        conn['spider21_database']['spider21_table'].inster_many({row})

报错信息：

数据：

应该是insert_many吧？

方法1:
insert_many 改成 insertOne
方法2:
insert_many({row}) 改成 insert_many(row)
