Import fails with transformers 5.0.0 - AutoModelForVision2Seq removed

[Clasyc]

py/smol.py fails to import with the newly released transformers 5.0.0:

ImportError: cannot import name 'AutoModelForVision2Seq' from 'transformers'

The requirements.txt specifies transformers>=4.45.0 with no upper bound, so pip installs 5.0.0 which removed AutoModelForVision2Seq.

Workaround: Pin to transformers>=4.45.0,<5.0.0
Suggested fix: Update requirements.txt:

- transformers>=4.43.2
+ transformers>=4.43.2,<5.0.0

Or update the import in py/smol.py to use the new transformers 5.0 API if AutoModelForVision2Seq was renamed/moved.
