在Windows环境中使用pandas读取包含中文列名的CSV文件时，遇到了OSError和UnicodeDecodeError。通过改变工作目录、指定GBK编码成功解决了读取问题。

从windows操作系统本地读取csv文件报错

data = pd.read_csv(path)

Traceback (most recent call last):

File "C:/Users/arron/PycharmProjects/ML/ML/test.py", line 45, in

data = pd.read_csv(path)

File "C:\Users\arron\AppData\Local\Continuum\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 655, in parser_f

return _read(filepath_or_buffer, kwds)

File "C:\Users\arron\AppData\Local\Continuum\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 405, in _read

File "C:\Users\arron\AppData\Local\Continuum\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 1582, in __init__

self._reader = parsers.TextReader(src, **kwds)

File "pandas\_libs\parsers.pyx", line 394, in pandas._libs.parsers.TextReader.__cinit__ (pandas\_libs\parsers.c:4209)

File "pandas\_libs\parsers.pyx", line 712, in pandas._libs.parsers.TextReader._setup_parser_source (pandas\_libs\parsers.c:8895)

OSError: Initializing from file failed

上述报错的解决方案是

pwd = os.getcwd()

os.chdir(os.path.dirname(path))

data = pd.read_csv(os.path.basename(path))

os.chdir(pwd)

此时又报如下错误：

Traceback (most recent call last):

File "C:/Users/arron/PycharmProjects/ML/ML/test.py", line 47, in

data = pd.read_csv(os.path.basename(path))

File "C:\Users\arron\AppData\Local\Continuum\Anaconda3\lib\site-packages\pandas\io\parsers.py", line 655, in parser_f

return _read(filepath_or_buffer, kwds)

self._make_engine(self.engine)

self._engine = CParserWrapper(self.f, **self.options)

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd7 in position 0: invalid continuation byte

最终解决方案是：

pwd = os.getcwd()

os.chdir(os.path.dirname(path))

data = pd.read_csv(os.path.basename(path),encoding='gbk')

os.chdir(pwd)
