Since `requests.Session` is not guaranteed to be thread-safe, `huggingface_hub` creates one session instance per thread.
Using sessions allows us to keep the connection open between HTTP calls and ultimately save time. If you are
integrating `huggingface_hub` in a third-party library and wants to make a custom call to the Hub, use [`get_session`]
to get a Session configured by your users (i.e. replace any `requests.get(...)` call by `get_session().get(...)`).
