PEFT Prompt Tuning: forward() got an unexpected keyword argument 'inputs_embeds'

[mikeleske]

Has someone successfully applied to Prompt Tuning PEFT to EVO?

With the HF SFT Trainer and the following PEFT config

    peft_config = PromptTuningConfig(
        task_type=TaskType.CAUSAL_LM,
        num_virtual_tokens=128,
        tokenizer_name_or_path='togethercomputer/evo-1-131k-base'
    )
    peft_model = get_peft_model(model, peft_config)
    peft_model.print_trainable_parameters()

I get the following error:

TypeError: forward() got an unexpected keyword argument 'inputs_embeds'

Any pointer on what I am doing wrong would be largely appreciated.

I'm getting the exact same error, is there any update on this?

I was able to fix this by using model.add_adapter(lora_config,adapter_name="abc") instead of get_peft_model(model, peft_config)`
