python 使用read_csv读取 CSV 文件时报错

读取csv文件时报错 

df = pd.read_csv('c:/Users/NUC/Desktop/成绩.csv' )

Traceback (most recent call last):
  File "D:/学习/helloworld/helloworld.py", line 268, in <module>
    df = pd.read_csv('c:/Users/NUC/Desktop/成绩.csv' )

    return _read(filepath_or_buffer, kwds)

OSError: Initializing from file failed

解决：

df = pd.read_csv('c:/Users/NUC/Desktop/成绩.csv', engine='python' )
加上 engine = 'python'
engine的参数有三个  'c','python','python_fwf'
