在用pycharm运行深度神经网络加载数据时，发现报错

Traceback (most recent call last):

File “D:/PyCharmWorkPlace/graduate_project/lsgan/main.py”, line 16, in

class LSGAN:

File “D:/PyCharmWorkPlace/graduate_project/lsgan/main.py”, line 125, in LSGAN

dataset = dset.ImageFolder(root=dataroot,

super().init(

File “D:\welcomeminiconda\envs\tensorflow\lib\site-packages\torchvision\datasets\folder.py”, line 145, in init

classes, class_to_idx = self.find_classes(self.root)

File “D:\welcomeminiconda\envs\tensorflow\lib\site-packages\torchvision\datasets\folder.py”, line 219, in find_classes

return find_classes(directory)

File “D:\welcomeminiconda\envs\tensorflow\lib\site-packages\torchvision\datasets\folder.py”, line 43, in find_classes

raise FileNotFoundError(f”Couldn’t find any class folder in {directory}.”)

FileNotFoundError: Couldn’t find any class folder in D:/PyCharmWorkPlace/graduate_project/data/graydata/.

在这里插入图片描述

这里的原因是ImageFolder调用的是一个数据包

我的png文件路径是D:/PyCharmWorkPlace/graduate_project/data/graydata/.

在这里插入图片描述

此时应该把路径写为图片的上一级目录，所以添加一个文件夹，将路径改为

D:/PyCharmWorkPlace/graduate_project/data/gray/

在这里插入图片描述

问题解决！
