阅读MSR意译语料库为大熊猫

我从MSR下载MSR复述语料库，并试图把它载入数据帧，但得到了以下错误：阅读MSR意译语料库为大熊猫

import pandas as pd 
df = pd.read_csv(r'C:\MSRParaphraseCorpus\msr_paraphrase_test.txt', sep = '\t')

错误：

所以我看了看线34，看起来非常好。

fname = r'C:\MSRParaphraseCorpus\msr_paraphrase_test.txt' 
    with open(fname, encoding="utf8") as f: 
     content = f.readlines() 

    content[34]

输出：

'0\t1268500\t1268733\tAgainst the Japanese currency, the euro was at 135.92/6.04 yen against the late New York level of 136.03/14.\tThe dollar was at 117.85 yen against the Japanese currency, up 0.1 percent.\n'

有什么想法？

P.S.添加一些更多的细节，因为SO会让我发帖而没有详细信息...

34行实际上是内容[33]和该行的问题是，最后一个字段有一个开始报价，但没有结束。你需要做pd.read_csv（r'C：\ MSRParaphraseCorpus \ msr_paraphrase_test.txt'，sep ='\ t'，quotechar =''）让csv阅读器忽略引号。不作为答案张贴，因为在解决该问题之后尝试加载文件还有其他问题。额外的问题不会跳出来，错误不是很清楚。但我会看起来更多一点。 – clockwatcher

问题在于第34行的开引号（正如我的评论中提到的）。通过传入csv.QUOTE_NONE来禁用csv阅读器的引用。尝试：

import csv 
import pandas as pd 

df = pd.read_csv(r'C:\MSRParaphraseCorpus\msr_paraphrase_test.txt', sep = '\t', quoting=csv.QUOTE_NONE)
