尝试在 Colab 中使用 pytorch torch.datasets.ImageFolder 加载训练数据。

transform = transforms.Compose([transforms.Resize(400),
                                transforms.ToTensor()])
dataset_path = 'ss/'
dataset = datasets.ImageFolder(root=dataset_path, transform=transform)
dataloader = torch.utils.data.DataLoader(dataset, batch_size=20)

我遇到了以下错误：

---------------------------------------------------------------------------

----> 4 dataset = datasets.ImageFolder(root=dataset_path, transform=transform)
      5 dataloader = torch.utils.data.DataLoader(dataset, batch_size=20)
