Sentence-transformer: No such file or directory error
### System Info

Using the sentence-transformer widget leads to the following error at https://huggingface.co/NbAiLab/nb-sbert:
`[Errno 2] No such file or directory: '/data/NbAiLab_nb-sbert/1_Pooling/config.json'`
I have checked all the config files, and can not find any references to this. 
I am able to load the model locally (from the HF repo), and do valid calculations. The only thing that does not work is the widget.
I found this on the discussion forum: https://discuss.huggingface.co/t/sentence-similarity-demo-not-working/8711
Any idea about what is happening here?

### Who can help?

@Narsil @LysandreJik

### Information

- [ ] The official example scripts
- [ ] My own modified scripts

### Tasks

- [ ] An officially supported task in the `examples` folder (such as GLUE/SQuAD, ...)
- [X] My own task or dataset (give details below)

### Reproduction

1. Open https://huggingface.co/NbAiLab/nb-sbert
2. In the widget, use Example 1 or fill in sentences
3. Press "compute"

### Expected behavior

Widget providing sentence similarities
Fixed now.

The culprit is either the way the api works or sentence-transformers, but `sentence-transformers` is not great at dealing with missing files (it looks only for 1 file and assumes the rest is there, leading to the failure you are seeing).

Since the API uses massive storage to handle all the models on the hub, there is periodical cleaning of unused files, and sometimes it happens that sentence-transformers doesn't access all the files at the same time, leading to only partial cleanup of sentence-transformers model files and to this error.

Hope you understand a bit better what happened.
For the fix we'll see about maybe adding something upstream, but can't make any promises.<|||||>This issue has been automatically marked as stale because it has not had recent activity. If you think this still needs to be addressed please comment on this thread.
