The error in PEFT is occurring after this transformers change: huggingface/transformers#33870 Now, in our tests, some model_kwargs no longer necessarily contain past_key_values, resulting in a KeyError. We now account for this possibility. Affected models were opt and gpt2.

Now, in our tests, some model_kwargs no longer necessarily contain past_key_values, resulting in a KeyError. We now account for this possibility. Affected models were opt and gpt2.
Example of failing CI: https://github.com/huggingface/peft/actions/runs/11256453704/job/31298371856
Note that CI won't detect this issue as it requires the latest transformers install. I ran this locally using
pytest tests/test_decoder_models.py -k "(prefix or prompt) and (opt or gpt2)" -v.
