將 CSV 導入 Pandas 時出現編碼錯誤

Question

我正在嘗試將此 csv 導入 pandas，但出現錯誤。 這是我的代碼：

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

當我運行它時，我得到這個錯誤：

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

pandas/_libs/parsers.pyx in pandas._libs.parsers._string_box_utf8()

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

During handling of the above exception, another exception occurred:

這是什么意思，我該如何解決？ 我嘗試使用此處解釋的解決方案，但沒有成功： https://www.kaggle.com/paultimothymooney/how-to-resolve-a-unicodedecodeerror-for-a-csv-file 。

Here's a link to the csv (warning, the file is 170mb): https://www2.census.gov/programs-surveys/popest/datasets/2010-2019/counties/asrh/cc-est2019-alldata.csv

我該如何解決這個錯誤？

提前致謝。

試試這個編碼：

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