更新答案

向@alvas道歉，我没有看到原始帖子中有完整的数据集链接。在所有的行中确实有五列，问题似乎是引号不匹配。如果列中没有匹配的引号，SFrameCSV解析器会感到困惑，因此简单的答案是将引号字符更改为数据集中没有出现的字符。在

import graphlab
sts = graphlab.SFrame.read_csv('sts.csv', delimiter='\t',
                                column_type_hints=[str, str, float, str, str],
                                quote_char='\0')

这为我成功地读取了19097行。在

另外，还有一个SFrame.read_csv_with_errors方法，它将把“好”行读入SFrame，并在未解析的SArray中收集“坏”行。这样就可以用编程的方式跟踪有问题的行。在

原始答案

您的数据行似乎不包含任何引号，因此这不是问题所在。问题是在某些数据行（和标题）中有5列，而在其他数据行中只有4列。在

第一行有四列：

^{pr2}$

第二排有五个：

STS2012-gold    surprise.OnWN   3.250   nations unified by shared interests, history or institutions    a group of nations having common interests.

为了解决这个问题，我将调用SFramecsv解析器两次，一次用于四列数据，一次用于五列数据。因为第一个fow有四个列，所以这一列更简单：

import graphlab
sts4 = graphlab.SFrame.read_csv('sts.csv', delimiter='\t', header=True)

对于五列数据，我们必须跳过标题和第一行，然后重命名列：

sts5 = graphlab.SFrame.read_csv('sts.csv', delimiter='\t', 
                                header=False, skiprows=2)
sts5 = sts5.rename({'X1': 'Dataset', 'X2': 'Domain', 'X3': 'Score',
                    'X4': 'Sent1', 'X5': 'Sent2'})

那么sts4看起来像

+       +       -+   -+               -+
|   Dataset    |     Domain    | Score |             Sent1             |
+       +       -+   -+               -+

+       +       -+   -+               -+

并且sts5是

+       +       -+   -+               -+
|   Dataset    |     Domain    | Score |             Sent1             |
