Question

我正在尝试将此 csv 导入到 Pandas，但出现错误。这是我的代码：

import pandas as pd
df = pd.read_csv("cc-est2019-alldata.csv")

当我运行它时，我收到此错误：

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

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf1 in position 2: invalid continuation byte

During handling of the above exception, another exception occurred:

这是什么意思，我该如何解决？我尝试使用此处解释的解决方案，但没有奏效：https://www.kaggle.com/paultimothymooney/how-to-resolve-a-unicodedecodeerror-for-a-csv-file。

这是 csv 的链接（警告，文件大小为 170mb）：https://www2.census.gov/programs-surveys/popest/datasets/2010-2019/counties/asrh/cc-est2019-alldata.csv

我该如何解决这个错误？

提前致谢。

试试这个编码：

df = pd.read_csv("cc-est2019-alldata.csv", encoding='latin1')

将 CSV 导入 Pandas 时出现编码错误
