我正在运行一个程序,它正在处理3万个类似的文件。随机数量的它们停止并产生此错误…

  File "C:\Importer\src\dfman\importer.py", line 26, in import_chr
    data = pd.read_csv(filepath, names=fields)
  File "C:\Python33\lib\site-packages\pandas\io\parsers.py", line 400, in parser_f
    return _read(filepath_or_buffer, kwds)
  File "C:\Python33\lib\site-packages\pandas\io\parsers.py", line 205, in _read
    return parser.read()
  File "C:\Python33\lib\site-packages\pandas\io\parsers.py", line 608, in read
    ret = self._engine.read(nrows)
  File "C:\Python33\lib\site-packages\pandas\io\parsers.py", line 1028, in read

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xda in position 6: invalid    continuation byte

这些文件的来源/创建都来自同一个地方。纠正这个问题以继续导入的最佳方法是什么?


当前回答

with open('filename.csv') as f:
   print(f)

执行这段代码后,你会发现'filename.csv'的编码,然后执行如下代码

data=pd.read_csv('filename.csv', encoding="encoding as you found earlier"

好了

其他回答

我遇到的另一个导致同样错误的重要问题是:

_values = pd.read_csv("C:\Users\Mujeeb\Desktop\file.xlxs")

^这一行导致了同样的错误,因为我正在使用read_csv()方法读取excel文件。使用read_excel()读取.xlxs

你可以试试这个。

import csv
import pandas as pd
df = pd.read_csv(filepath,encoding='unicode_escape')

试试这个:

import pandas as pd
with open('filename.csv') as f:
    data = pd.read_csv(f)

看起来它会处理编码,而不会通过参数显式地表示它

在传递给熊猫之前检查编码。它会让你慢下来,但是……

with open(path, 'r') as f:
    encoding = f.encoding 

df = pd.read_csv(path,sep=sep, encoding=encoding)

在python 3.7中

尝试改变编码。 在我的例子中,encoding = "utf-16"起作用了。

df = pd.read_csv(“file.csv”,encoding='utf-16')
