Chapter 04 -pin peft version compatible with transformers==4.41.2 ImportError: cannot import name 'EncoderDecoderCache' from 'transformers' (/usr/local/lib/python3.12/dist-packages/transformers/

[seanv507]

Problem

The Supervised classification fails because of an implicit install of peft which imports EncoderDecoderCache from transformers.

/usr/local/lib/python3.12/dist-packages/peft/peft_model.py in
37 from torch.nn import BCEWithLogitsLoss, CrossEntropyLoss, MSELoss
---> 38 from transformers import Cache, DynamicCache, EncoderDecoderCache, PreTrainedModel
39 from transformers.modeling_outputs import QuestionAnsweringModelOutput, SequenceClassifierOutput, TokenClassifierOutput

ImportError: cannot import name 'EncoderDecoderCache' from 'transformers' (/usr/local/lib/python3.12/dist-packages/transformers/init.py)

Solution

pinning peft to 0.11.1 (as in requirements.txt ) solves this issue
