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: [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/.&nbsp;所以我假设，你应该更换dataroot&nbsp;=&nbsp;"Users/user1/Downloads/DCGANs/celeba/"经过dataroot&nbsp;=&nbsp;"/Users/user1/Downloads/DCGANs/celeba/"
