解决pandas read_csv 读取中文列标题文件报错的问题

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 <module>
  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 "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 <module>
  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)

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)
