python - Python：FileNotFoundError：文件 b'fleet.csv' 不存在

问题描述

FileNotFoundError当我尝试读取目录中的特定 CSV 文件时，我得到了一个。如果我读取另一个 CSV 文件，我可以正确读取它而不会出现任何错误。

我试过的

fleet_data=pd.read_csv('data_fleet.csv', sep=',',index_col=0)
fleet_data=pd.read_csv('Users/Ver/Desktop/Processing/data_fleet.csv',sep=',',index_col=0)
fleet_data=pd.read_csv('Users\Ver\Desktop\Processing\data_fleet.csv',sep=',',index_col=0)
fleet_data=pd.read_csv('data_fleet.csv')

我尝试更改文件的名称，但它仍然不起作用。

错误


fleet_data=pd.read_csv('data_fleet.csv', sep=',',index_col=0)

但

如果我将 CSV 文件从项目复制到另一个项目文件夹并打开 Python 文件并打开文件 (data_fleet.py)，我可以毫无问题地读取它。

读取所需文件夹中的文件有什么问题？

解决方案

尝试给它绝对路径：

'C:\\Users\\Ver\\Desktop\\Processing\\data_fleet.csv'
