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

Question

嘗試讀取目錄中的特定CSV文件時，出現FileNotFoundError 。 如果我讀取另一個CSV文件，則可以正確讀取它，而不會出現任何錯誤。

我嘗試過的

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')

我嘗試更改文件名，但仍然無法正常工作。

錯誤

fleet_data=pd.read_csv('data_fleet.csv', sep=',',index_col=0)
Traceback (most recent call last):

    FileNotFoundError: File b'data_fleet.csv' does not exist

但

如果我將CSV文件從項目復制到另一個項目文件夾，然后打開Python文件並打開文件（data_fleet.py），則可以毫無問題地讀取它。

讀取所需文件夾中的文件有什么問題？

Answer 1

嘗試給它絕對路徑：

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

Answer 2

您可以嘗試列出目錄的內容嗎？ 例如，使用os模塊和listdir()函數

>>> import os
>>> contents = os.listdir()
>>> contents

這將使您查看是否有任何奇數字符或某些東西阻止您“查找”
