当用pandas库读取.csv文件时，出现如下报错：
My Code:

impor tpandas as pd
df=pd.read_csv('C:\\Users\\登亮\\Desktop\\test.csv',encoding='utf-8')

Error:

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xd3 in position 0: invalid continuation byte

Reason：
In binary, 0xE9 looks like1110 1001. If you read about UTF-8 on Wikipedia, you’ll see that such a byte must be followed by two of the form 10xx xxxx. So, for example

>>>b'\xe9\x80\x80'.decode('utf-8')u'\u9000'

But that’s just the mechanical cause of the exception. In this case, you have a string that is almost certainly encoded in latin 1. You can see how UTF-8 and latin 1 look different:

>>>u'\xe9'.encode('utf-8')b'\xc3\xa9'>>>u'\xe9'.encode('latin-1')b'\xe9'

(Note, I'm using a mix of Python 2 and 3 representation here. The input is valid in any version of Python, but your Python interpreter is unlikely to actually show both unicode and byte strings in this way.)
Solution：
Ttry calling read_csv withen coding='latin1',encoding='iso-8859-1'orencoding='cp1252'; these the various encodings found on Windows.
