Pr 2374 ci branch (#2378)

* Update __init__.py

Fix issue with NoneType comparison for max_input_tokens and sliding_window

- Add default values for max_input_tokens and sliding_window to handle None cases.
- Ensure the comparison between max_input_tokens and sliding_window is handled correctly to prevent TypeError.
- This change addresses the error: TypeError: '<=' not supported between instances of 'int' and 'NoneType'.

* Update __init__.py

Handle NoneType in sliding_window comparison to fix TypeError in __init__.py by ensuring the comparison logic accounts for NoneType values, preventing errors and improving code robustness.

* fix: syntax/style tweak
