Question

我正在尝试对某些文档进行标记，但我有这个错误

UnicodeDecodeError：'ascii'编解码器无法解码字节0xef的位置 6：序数不在范围内（128）

import nltk
import pandas as pd

df = pd.DataFrame(pd.read_csv('status2.csv'))
documents = df['status']

result = [nltk.word_tokenize(sent) for sent in documents]

我认为这是unicode问题所以我添加了

documents = unicode(documents, 'utf-8')

另一个错误

TypeError：强制转换为Unicode：需要字符串或缓冲区，找到系列

print documents

Answer 1

unicode对字符串或字节进行操作，但documents是一个pandas系列。

也许：

result = [nltk.word_tokenize(unicode(sent, 'utf-8')) for sent in documents]

python标记化UnicodeDecodeError
