我正在使用python导入数据集,但它不起作用,熊猫,numpy和seaborn导入效果很好。

我尝试使用完整路径和短路径(数据集和python文件在同一文件夹中...)。

我的代码:

import pandas as pd
import seaborn as sns
import numpy as np

pd.read_csv("dataset.csv")

我们可以看到这可能是编码问题,但我输入了enconding ='utf_8',没有附加内容。 最后一条错误消息是:

---------------------------------------------------------------------------
UnicodeDecodeError                        Traceback (most recent call last)

During handling of the above exception, another exception occurred:
