使用 tfds.load() 无法访问 CelebA 数据集

我正在尝试在深度学习项目中使用 CelebA 数据集。我有来自 Kaggle 的压缩文件夹。 我想解压缩，然后将图像拆分为训练、测试和验证，但后来发现这在我的设备上是不可能的不那么强大 system.

因此，为了避免浪费时间，我想使用 TensorFlow-datasets 方法来加载 CelebA 数据集。但不幸的是，数据集无法访问，并出现以下错误：

（代码先）

ds = tfds.load('celeb_a', split='train', download=True)

有人可以解释我做错了什么吗？

顺便说一句，如果这不起作用，有没有办法将已经从 Kaggle 下载的压缩文件转换为所需的格式，而无需解压缩，然后单独迭代每个图像？基本上我不能往下走解压缩然后分割如此大的数据集的路线...

TIA!

EDIT: I tried the same on Colab, but getting a similar error:
