试图在 Pandas 中读取 .csv 文件的文件 url，返回文件未找到

Question

这是我上课期间的练习，我无法参加，所以我私下赶上。 我正在尝试使用 Pandas 读取我的 .csv 文件。我正在使用 Jupiter，并在我的 Jupiter 中正确上传了 .csv 文件。 但由于某种原因，我的代码无法读取我的文件。

你能知道为什么吗？ 谢谢！ ** 示例数据：HR 员工流失率和绩效 ** 您可以从此处获取： 我已经从以下 url 下载了这个文件，并将它上传到我的 Jupiter。 https://www.kaggle.com/patelprashant/employee-attrition#WA_Fn-UseC_-HR-Employee-Attrition.csv

file_url = "HR_Employee_Attrition.csv"

data = pd.read_csv(file_url)

​ data.head()##->同data.head(5)

<ipython-input-19-201da5b1caca> in <module>
----> 1 data = pd.read_csv(file_url)
      2 # here the rows are being indexed by one of the columns ->  'EmployeeNumber'
      3 # all other column headings of the csv file would become columns.
      4 
      5 data.head()  ## same as data.head(5)

我认为 pd.read 函数 csv 参数中 csv 的位置不正确。所以检查csv文件的路径（在参数中提供完整的路径位置字符串）。
