cc @nreimers <|||||>The issue is known and has to do with some cache file cleaning we use for the widgets: Files older than 30 days are deleted, but this causes some issues with the caching system of sentence-transformers.

 @osanseviero has posted a PR in sentence-transformers that will re-download files. The PR is merged in sentence-transformers and will soon pushed to pip. It will then solve this issue. <|||||>[This](https://github.com/UKPLab/sentence-transformers/pull/1116) is the PR for reference. I'll update this issue once all changes are pushed to pip + deployed in the API.<|||||>The newest version of sentence-transformers is pushed to pip: version 2.1.0

It can now be deployed in the API.<|||||>This will be fixed with https://github.com/huggingface/huggingface_hub/pull/383 deployment<|||||>This is fixed now!
