If you copy paste the code from hugging face SFTTrainer page ([Supervised Fine-tuning Trainer](https://huggingface.co/docs/trl/main/en/sft_trainer)) it results in error:

name ‘PeftModel’ is not defined

Code:  
trainer = SFTTrainer(  
“facebook/opt-350m”,  
train\_dataset=dataset,  
dataset\_text\_field=“text”,  
max\_seq\_length=512,  
)  
trainer.train()
