Pytorch 无法识别数据集的目录

Question

我正在尝试在我的 Mac 上运行来自官方 PyTorch 站点 ( 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---------------------------------------------------------------------------FileNotFoundError                         Traceback (most recent call last)<ipython-input-6-1019cc990fb4> in <module>() 78                                transforms.CenterCrop(image_size), 79                                transforms.ToTensor(),---> 80                                transforms.Normalize((0.5, 0.5, 0.5), (0.5, 0.5, 0.5)), 81                            ])) 82 # Create the dataloader/anaconda3/lib/python3.6/site-packages/torchvision/datasets/folder.py in __init__(self, root, transform, target_transform, loader)176         super(ImageFolder, self).__init__(root, loader, IMG_EXTENSIONS,177                                           transform=transform,--> 178                                           target_transform=target_transform)179         self.imgs = self.samples/anaconda3/lib/python3.6/site-packages/torchvision/datasets/folder.py in __init__(self, root, loader, extensions, transform, target_transform) 73  74     def __init__(self, root, loader, extensions, transform=None, target_transform=None):---> 75         classes, class_to_idx = find_classes(root) 76         samples = make_dataset(root, class_to_idx, extensions) 77         if len(samples) == 0:/anaconda3/lib/python3.6/site-packages/torchvision/datasets/folder.py in find_classes(dir) 21  22 def find_classes(dir):---> 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/"我在 Atom 和 Jupyter Notebook 上都试过这个，没有什么区别。非常感谢所有帮助:)

Answer 1

可识别的目录结构以/. 所以我假设，你应该更换

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

经过

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