我已将其读入graphlab.SFrame使用read_csv()函数：
import graphlab
sts = graphlab.SFrame.read_csv('sts.csv', delimiter='\t', column_type_hints=[str, str, float, str, str])
并且有些行未解析。回溯如下：

Sent1看看这些行，如果我的或Sent2列中的任何一个包含奇数双引号，似乎就有问题了。
使用error_bad_lines来跟踪有问题的行：
sts = graphlab.SFrame.read_csv('sts.csv', delimiter='\t', column_type_hints=[str, str, float, str, str],
error_bad_lines=True)
它抛出回溯：

如果我的行包含奇数个双引号，有没有办法解决这个问题？
有没有办法在不清理数据的情况下做到这一点（例如，识别有问题的行，然后清理/更正它们，但保留另一个 SFrame 来跟踪清理/更正？
作为健全性检查，如果我们\t在原始 csv 文件中进行搜索，行中有一个选项卡会出现问题，但在graphlab解析它时，它会消失：
作为另一个完整性检查，逐行读取文件并将其拆分\t为整个文件返回 5 列：
