如何在加载数据集时解析Pandas 'read_csv‘中的“read_csv”
提问于 2020-04-11 12:35:37
我正在使用CSV文件中的一个销售数据集。当我尝试用熊猫read_csv方法加载这个数据集时，我得到了一个错误UnicodeDecodeError: 'ascii' codec can't decode byte 0xae in position 16: ordinal not in range(128)，我不知道如何解决这个问题。我搜索了它，得到了，仍然无法解决我的问题。我尝试了以下方法
import pandas as pd
sales=pd.read_csv("Superstore-Sales.csv")
sales.head(5)这里是全错误

看看sales=pd.read_csv("Superstore-Sales.csv", encoding='latin1')能不能帮上忙。

你可以试试这个：
address = (r"C:\--------------------/Superstore-Sales.csv")
sales = pd.read_csv(address, encoding='latin1')
