# What does this PR do?

Fix `CONFIG_ARCHIVE_MAP_MAPPING_NAMES` as reported in #21204.
Also, `UPERNET_PRETRAINED_CONFIG_ARCHIVE_MAP` doesn't exist.

Remark: we have planned deprecation
```
        warnings.warn(
            "ALL_PRETRAINED_CONFIG_ARCHIVE_MAP is deprecated and will be removed in v5 of Transformers. "
            "It does not contain all available model checkpoints, far from it. Checkout hf.co/models for that.",
            FutureWarning,
        )
```

Fix #21204
_The documentation is not available anymore as the PR was closed or merged._<|||||>I will merge as it is - don't think it matters (at least not at this moment), and eventually this is going to be deprecated.
