python - “utf-8”编解码器无法解码位置 28 中的字节 0xa3：无效的起始字节

问题描述

我正在尝试使用 pandas 库从谷歌驱动器中读取 CSV 文件。
但是，我遇到了一个问题“UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa3 in position 28: invalid start byte”

我的代码

df = pd.read_csv("/content/gdrive/My Drive/data/OnlineRetail.csv")

输出

---------------------------------------------------------------------------
UnicodeDecodeError                        Traceback (most recent call last)
pandas/_libs/parsers.pyx in pandas._libs.parsers.TextReader._convert_tokens()

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

UnicodeDecodeError: 'utf-8' codec can't decode byte 0xa3 in position 28: invalid start byte

During handling of the above exception, another exception occurred:

解决方案

有同样的问题。它可能不是 utf-8 编码。试着弄清楚它是什么。您可以通过在 Notepad++ 中打开它来做到这一点。顶部有编码菜单，看看选择了什么。
