Can the transformer models run without any local storage at all?
### Feature request

We have a use case where we'd like to download transformer models from our S3 or other storage location directly into memory (without saving it in local storage), finetune the model and save the final model directly to the remote storage through an API.

We're wondering if this use case of not using local storage at all is possible using the current library?

### Motivation

Our usecase requires minimizing local storage usage.

### Your contribution

We are trying to figure out if this feature is already supported
This is indeed to supported by the library.<|||||>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.
