我正在尝试在我的 Mac 上运行 PyTorch 官方网站 ( 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

FileNotFoundError: [Errno 2] No such file or directory: 'Users/user1/Downloads/DCGANs/celeba/'
这是我尝试加载数据集的位置，其中dataroot =“Users/user1/Downloads/DCGANs/celeba/”
数据集是一个文件夹(名为 celeba)，包含大约 200,000 张图像。
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 上都尝试过这个，没有什么区别。
非常感谢所有帮助:)
最佳答案
可识别的目录结构以/开头。所以我认为，你应该更换
dataroot = "Users/user1/Downloads/DCGANs/celeba/"
由
dataroot = "/Users/user1/Downloads/DCGANs/celeba/"
关于python - Pytorch 无法识别数据集的目录，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53916510/
