python数据挖掘关联分析Apriori算法报错

   用python学习数据挖掘关联分析的时候，看到一篇别人的博客，然后我自己运行的时候报错了，并且在网上搜索到对应的错误原因都不是我这个
   我看的博客网址(https://blog.csdn.net/weixin_39559994/article/details/107200440?ops_request_misc=%257B%2522request%255Fid%2522%253A%2522165391141616781435469762%2522%252C%2522scm%2522%253A%25222014071?%ra=link3.130102334..%2522%257D&request_id=165391141616781435469762&biz_id=0&utm_medium=distribute.pc_search_result.none-task-blog-2~all~sobaiduend~default-2-107200440-null-null.142)
   下面是我的代码

import pandas as pd
data = pd.read_excel('电影推荐系统.xlsx')
# print(data)
user_movie = data.pivot_table(index = '用户编号', columns = '名称', values = '评分')
# print(user_movie)
bool_data = user_movie.notnull()
bool_data
# print(bool_data)
from mlxtend.frequent_patterns import apriori
items = apriori( bool, min_support=0.2, use_colnames=True)
from mlxtend.frequent_patterns import association_rules
relues = association_rules(items, min_threshold=0.7)
# relues
print(relues)

报错原因：

请问有人能告诉我这是怎么回事吗？谢谢各位了
