AttributeError: 'Config' object has no attribute '_get_non_default_generation_parameters'

System Info

transformers version: 4.47.1
I finetuned the rmbg-2.0 with my own dataset. When I save the model using model.save_pretrained, I got the error as follows:
File "/usr/lib/python3.10/site-packages/transformers/modeling_utils.py", line 2815, in save_pretrained
misplaced_generation_parameters = model_to_save.config._get_non_default_generation_parameters()
AttributeError: 'Config' object has no attribute '_get_non_default_generation_parameters'

Who can help?

Hi @XYZ-916, can you create some simple reproducer code we can run to diagnose this? For example, just load and save the model or even just the config and check if the bug still occurs
