【问题描述】:
我是在 Windows 上使用 Pandas 的新手,我不确定我在这里做错了什么。
我的数据位于'C:\Users\me\data\lending_club\loan.csv'
path = 'C:\\Users\\me\\data\\lending_club\\loan.csv'
pd.read_csv(path)
我得到这个错误:
---------------------------------------------------------------------------

编辑:
我重新安装了 Anaconda,错误消失了。不确定到底发生了什么,但可能与在我的第二次安装中初始安装是全局的还是特定于用户的有关。谢谢大家的帮助!
【问题讨论】:
-
不确定这里出了什么问题。我只是使用相对路径。 - 这不可能吗?
-
当您执行
print(os.listdir(your_path))时会发生什么?
