如何在 python 中提供 D 驱动器中文件夹的正确路径

Question

这是我的代码。基本上，我想循环加载D驱动器内文件夹中的所有图像。

from PIL import Image
def loadimages(path):
list=listdir(path)
loadedimages=[]
for image in list:
img=Image.open(path+image)
loadedimages.append(img)
return loadedimages
path= r"D:ACADEMICS8SEMPatternClassificationCBT-1TrainCharacters"
imgs=loadimages(path)

我收到这样的错误

Traceback (most recent call last):
File "<pyshell#26>", line 1, in <module>
imgs=loadimages(path)
File "<pyshell#11>", line 5, in loadimages
img=Image.open(path+image)
File "C:Usersanjana ousephAppDataLocalProgramsPythonPython37libsite-packagesPILImage.py", line 2809, in open
fp = builtins.open(filename, "rb")
FileNotFoundError: [Errno 2] No such file or directory: 'D:\ACADEMICS\8SEM\PatternClassification\CBT-1\TrainCharacters1'

Answer 1

如果图像位于 TrainCharacter 文件夹中，则缺少"\"

目前它正在寻找

'D:\ACADEMICS\8SEM\PatternClassification\CBT-1\TrainCharacters1'

您可能需要

'D:\ACADEMICS\8SEM\PatternClassification\CBT-1\TrainCharacters\1'

Answer 2

看来问题是行img=Image.open(path+image)。 我建议使用内置的 Python 路径操作方法os.path.join：

from PIL import Image
import os
def loadimages(path):
list=listdir(path)
loadedimages=[]
for image in list:
img=Image.open(os.path.join(path, image))
loadedimages.append(img)
return loadedimages
path= r"D:ACADEMICS8SEMPatternClassificationCBT-1TrainCharacters"
imgs=loadimages(path)
