Info on Original Adapter Hub Repo Archival

[calpt]

Within the last few weeks, we have archived the "original" Hub repository (found at: https://github.com/adapter-hub/Hub) released alongside our initial AdapterHub release in 2020 (announcement). This post summarizes all important points on the archival.

Hub infrastructure

• The Hub repository on GitHub is now in read-only mode, meaning no new adapters can be added there. It will remain accessible for reference purposes.
• It remains recommended to upload all new adapters to the Hugging Face Model Hub, which will be the only supported Hub for Adapters in the future. Read our docs: https://docs.adapterhub.ml/huggingface_hub.html
• We have moved all ~300 publicly accessible adapters, including all of our original collection and most third-party contributions over to the Hugging Face Model Hub, ensuring they stay accessible in the future

Compatibility in Adapters

>= v0.2.2

Attempting to load adapters from the original Hub repo will automatically redirect to loading the same adapter from the Hugging Face Model Hub. There is no breaking change in existing code, the same adapter weights will be loaded. Additionally, a warning is issued to switch to the corresponding adapter ID for the Hugging Face Model Hub. Explicitly adding source='ah' will still load from the original source.

>= v1.0.0

Loading from the original Hub repo will be removed. The source parameter in load_adapter(), list_adapters() and get_adapter_info() will be removed. All adapters identified by adapter IDs will always load from Hugging Face Model Hub. Old adapter IDs will continue to redirect and issue a warning.

Additionally, push_adapter_to_hub() will no longer support specifying an AdapterHub tag to upload adapters.
