Question

因此，我尝试在jupyter笔记本中导入一个csv文件，但出现错误。我写的代码是：

import pandas as pd
df = pd.read_csv('all_stocks_5yr.csv')
df.head()

但是我得到了错误：

 FileNotFoundError                         Traceback (most recent call last)

          3 
    ----> 4 df = pd.read_csv('all_stocks_5yr.csv')
          5 df.head()

我尝试过使用其他csv文件，如果我通过转到属性，然后使用位置并使用它来说出确切位置，那么我会收到错误消息：OSError: Initializing from file failed

为什么无法将csv文件导入jupyternotebook？
