python - Pytorch 无法识别数据集的目录

问题描述

我正在尝试在我的 Mac 上运行来自官方 PyTorch 网站 ( https://pytorch.org/tutorials/beginner/dcgan_faces_tutorial.html ) 的深度卷积 GAN 代码。

当我尝试加载数据时，我不断收到“FileNotFound”错误。

Random Seed:  999

 76         samples = make_dataset(root, class_to_idx, extensions)
 77         if len(samples) == 0:

---> 23     classes = [d for d in os.listdir(dir) if os.path.isdir(os.path.join(dir, d))]
 24     classes.sort()
 25     class_to_idx = {classes[i]: i for i in range(len(classes))}

FileNotFoundError: [Errno 2] No such file or directory: 'Users/user1/Downloads/DCGANs/celeba/'

这是我尝试加载数据集的地方dataroot = "Users/user1/Downloads/DCGANs/celeba/"

数据集是一个包含大约 200,000 张图像的文件夹（名为 celeba）。

dataset = dset.ImageFolder(root=dataroot,
                       transform=transforms.Compose([
                           transforms.Resize(image_size),
                           transforms.CenterCrop(image_size),
                           transforms.ToTensor(),
                           transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5)),
                       ]))

我在 Atom 和 Jupyter Notebook 上都试过这个，但没有任何区别。

高度赞赏所有帮助:)

解决方案

可识别的目录结构以/. 所以我认为，你应该更换

dataroot = "Users/user1/Downloads/DCGANs/celeba/"

经过

dataroot = "/Users/user1/Downloads/DCGANs/celeba/"
