请问这是为什么 FileNotFoundError: [Errno 2] No such file or directory

Question

import os

from torch.utils.data import Dataset
from utils import *
from torchvision import transforms

transform = transforms.Compose([
    transforms.ToTensor()
])


class MyDataset(Dataset):
    def __init__(self, path):
        self.path = path
        self.name = os.listdir(os.path.join(path, 'imangesPng'))

    def __len__(self):
        return len(self.name)

    def __getitem__(self, index):
        tag_name = self.name[index]
        tag_path = os.path.join(self.path, 'imangesPng', tag_name)
        img_path = os.path.join(self.path, 'imangesJpeg', tag_name.replace('png', 'jpg'))
        tag_imange = keep_image_size_open(tag_path, (1024, 1024))
        imanges = keep_image_size_open(img_path, (1024, 1024))
        return transform(imanges), transform(tag_imange)


if __name__ == '__main__':
    data = MyDataset(r'E:\pycharm\XrayFemurDivision\unet_model\Imanges')
    print(data[0][0].shape)
    print(data[0][1].shape)

尝试过将目录的连接符改为\

Answer 1

    tag_path = os.path.join(self.path, 'imangesPng', tag_name)
    img_path = os.path.join(self.path, 'imangesJpeg', tag_name.replace('png', 'jpg'))

应该是这部分代码问题，这个是在你的文件夹没有相应图片
