InterfaceError：执行操作失败； Python类型numpy.int64无法转换

Question

我不知道问题出在哪里！有人可以帮助我吗？

cnx = mysql.connector.connect（用户='root'，密码='suraj1697'，主机='127.0.0.1'，数据库='模型'） mycursor = cnx.cursor（） sql =“ INSERT INTO model2（length，host_length，path_length，fd_length，tld_length，count1，count2，count3，count4，count5，count6，count_http，count_https，count_www，count_digit，count_letter，count_dir，count_ip，count_short）VALUES（％d， ％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d，％d ，％d）” 打印（SQL） 数据= [] 对于范围（1，32）中的i：

mycursor.execute（'创建数据库模型'）

mycursor.execute("ALTER TABLE model2(id INT AUTO_INCREMENT PRIMARY KEY,lenght INT,host_length INT,path_length INT,fd_length INT,tld_length INT,count1 INT,count2 INT,count3 INT,count4 INT,count5 INT,count6 INT,count_http INT,count_https INT,count_www INT,count_digit INT,count_letter INT,count_dir INT,count_ip INT,count_short INT)")
#record=[int(urldata['url_length'][i]),int(urldata['hostname_length'][i]),int(urldata['path_length'][i]),int(urldata['fd_length'][i]),int(urldata['tld_length'][i]),int(urldata['count-'][i]),int(urldata['count@'][i]),int(urldata['count?'][i]),int(urldata['count%'][i]),int(urldata['count.'][i]),int(urldata['count='][i]),int(urldata['count-http'][i]),int(urldata['count-https'][i]),int(urldata['count-www'][i]),int(urldata['count-digits'][i]),int(urldata['count-letters'][i]),int(urldata['count_dir'][i]),int(urldata['use_of_ip'][i]),int(urldata['short_url'][i])]
record=[urldata['url_length'][i],urldata['hostname_length'][i], urldata['path_length'][i], urldata['fd_length'][i], urldata['tld_length'][i], urldata['count-'][i],urldata['count@'][i], urldata['count?'][i], urldata['count%'][i], urldata['count.'][i], urldata['count='][i], urldata['count-http'][i], urldata['count-https'][i],urldata['count-www'][i], urldata['count-digits'][i], urldata['count-letters'][i],urldata['count_dir'][i], urldata['use_of_ip'][i], urldata['short_url'][i]]
data.append(record)

打印（数据） mycursor.executemany（sql，data） cnx.commit（）

您输入的数据之一是numpy.int6。简单的解决方案是将值封装在int（）中。正确的方法是使用numpy提供的astype（）方法。

例如：

  

variable.astype（int）
