python - 属性错误 : 'ElementTree' object has no attribute 'getiterator' when trying to import excel file

Question

这是我的代码。
我刚刚安装了 jupyterlab，并在其中添加了 excel 文件。
如果我将路径更改为文件在我的系统上的位置，则会出现同样的错误。
仅将 excel 文件作为数据框导入时，我似乎找不到任何遇到相同问题的人。
excel 文件是一个 3x26 表，其中包含 studentnr、course、result 列，其值分别为 101-105、A-D、1.0-9.9。也许问题出在excel文件上？
无论哪种方式，我都不知道如何解决这个问题。

import pandas as pd
import numpy as np
df = pd.read_excel('student-results.xlsx')

这是我得到的错误:

您可以尝试使用参数 engine="openpyxl" .它帮助我解决了同样的问题。
