加载数据集时如何解决 Pandas 'read_csv' 中的“UnicodeDecodeError”

Question

我正在处理 CSV 文件中的销售数据集。当我尝试使用 pandas read_csv 方法加载此数据集时，出现错误UnicodeDecodeError: 'ascii' codec can't decode byte 0xae in position 16: ordinal not in range(128) 我不知道如何解决此问题。我搜索它并得到this link，仍然无法解决我的问题。我尝试了以下

import pandas as pd

sales=pd.read_csv("Superstore-Sales.csv")
sales.head(5)

这是完整的错误

During handling of the above exception, another exception occurred:

Answer 1

看看，sales=pd.read_csv("Superstore-Sales.csv", encoding='latin1') 有没有帮助。

Answer 2

你可以试试这个：

address = (r"C:\--------------------/Superstore-Sales.csv")
sales = pd.read_csv(address, encoding='latin1') 
sales.head()
