python 导入数据错误：UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 0: invalid start

正想导入数据到python作分析

找到这个教程

https://www.cnblogs.com/OliverQin/p/8966321.html

我要导入CSV文件，已经放在相同目录之下。

import pandas as pd
data = pd.read_csv("电信客户流失.csv",encoding="utf8")

报错如下

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte

错误类型

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xb5 in position 0: invalid start byte

过了一会儿突然可以了，真实奇怪

这时我在看这篇博客，

https://blog.csdn.net/xxceciline/article/details/80405129

然后我再次运行，又出现错误

使用这个链接的方法

https://www.cnblogs.com/pengei/p/6407077.html

==========解决方案============

第一种：

　　第一行加:# -*- coding: utf-8 -*-

第二种：

　　引用处设置默认编码格式

　　# coding: utf-8

第三种：

　　使用中文处将中文unicode编码

python3以后第二种方式。

还是一样的报错

#-*- coding : utf-8 -*-
# coding: utf-8
import pandas as pd
data = pd.read_csv("电信客户流失.csv",encoding="utf-8")

我尝试这个方法行不通

在百度上的方法都解决不了，我用谷歌搜索解决方案

我的最终解决方案，来自这里

#-*- coding : utf-8 -*-
# coding: utf-8
import pandas as pd
data = pd.read_csv("电信客户流失.csv",encoding="unicode_escape")

说明刚才的错误没有了

 

用read_csv之后，里面加上encoding='gbk'就可以了。

 现在是什么问题都没有了
