[dss010101]

What happened + What you expected to happen

Recently upgraded from python 3.11.5 to 3.11.6. Now when im using ray, i get an exception at on the following line:

            ray.init(ignore_reinit_error=True)

2023-11-21 17:01:38,062	ERROR services.py:1398 --

**ModuleNotFoundError: No module named 'async_timeout'**

Now i think i can solve this by pip installing aync_timeout - but i want to understand why this dependency is now cropping up when it wasnt before...is it new?
