Question

我在Windows 10上安装了Anaconda 3.我使用pd.read_csv（）来加载csv文件，但是我收到了错误消息。首先，我尝试使用了df = pd.read_csv('C:\direct_marketing.csv')，并且导入了文件。

然后我尝试df = pd.read_csv('C:\tutorial.csv')并收到以下错误消息：

Traceback (most recent call last):

  File "<ipython-input-3-ce208cc2684f>", line 1, in <module>
    df = pd.read_csv('C:\tutorial.csv')

  File "C:\Users\Alexandros_7\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 562, in parser_f
    return _read(filepath_or_buffer, kwds)

  File "C:\Users\Alexandros_7\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 315, in _read
    parser = TextFileReader(filepath_or_buffer, **kwds)

  File "C:\Users\Alexandros_7\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 645, in __init__
    self._make_engine(self.engine)

  File "C:\Users\Alexandros_7\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 799, in _make_engine
    self._engine = CParserWrapper(self.f, **self.options)

  File "C:\Users\Alexandros_7\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 1213, in __init__
    self._reader = _parser.TextReader(src, **kwds)

  File "pandas\parser.pyx", line 358, in pandas.parser.TextReader.__cinit__ (pandas\parser.c:3427)

  File "pandas\parser.pyx", line 628, in pandas.parser.TextReader._setup_parser_source (pandas\parser.c:6861)

OSError: File b'C:\tutorial.csv' does not exist

然后我将文件移动到一个新文件夹并重命名，然后再次使用read.csv（）导入它：

df = pd.read_csv('C:\Users\test.csv')

这次我收到了一条不同的错误消息：

  File "<ipython-input-5-03c6d380c174>", line 1
    df = pd.read_csv('C:\Users\test.csv')
                    ^
SyntaxError: (unicode error) 'unicodeescape' codec can't decode bytes in position 2-3: truncated \UXXXXXXXX escape

你能帮我理解发生了什么以及如何处理这种情况吗？

非常感谢！

Answer 1

尝试转义反斜杠：

df = pd.read_csv('C:\\Users\\test.csv')

Answer 2

尝试使用两个反斜杠'\'而不是'\'。它可能会把它作为逃避标志..？

Answer 3

另一种选择是在路径r

之前添加df = pd.read_csv(r'C:\Users\test.csv')
