Broken download links for Caltech101 and Caltech256 datasets

[JonasKlotz]

🐛 Describe the bug

When invoking the download method within torchvision.datasets.Caltech101 and Caltech256, the current Google Drive URLs no longer resolve and yield an error stating “Sorry, the file you have requested does not exist. Make sure that you have the correct URL and that the file exists.” Thus, the dataset is not downloadable. Details
In the Caltech101.download implementation, the following calls are made:

download_and_extract_archive(
    "https://drive.google.com/file/d/137RyRjvTBkBiIfeYBNZBtViDHQ6_Ewsp",
    self.root,
    filename="101_ObjectCategories.tar.gz",
    md5="b224c7392d521a49829488ab0f1120d9",
)
download_and_extract_archive(
    "https://drive.google.com/file/d/175kQy3UsZ0wUEHZjqkUDdNVssr7bgh_m",
    self.root,
    filename="Annotations.tar",
    md5="6f83eeb1f24d99cab4eb377263132c91",
)

When these URLs are accessed directly, a 404‐style response is returned instead of the expected archive.

Similarly, in Caltech256.download, the code uses:

download_and_extract_archive(
    "https://drive.google.com/file/d/1r6o0pSROcV1_VwT4oSjA2FBUSCWGuxLK",
    self.root,
    filename="256_ObjectCategories.tar",
    md5="67b4f42ca05d46448c6bb8ecd2220f6d",
)

This Google Drive link also appears inactive.

Observed Error Message

Sorry, the file you have requested does not exist.
Make sure that you have the correct URL and that the file exists.

Thanks
