The method is described in detail in https://huggingface.co/papers/2205.05638 Args: model ([`~transformers.PreTrainedModel`]): The model to be adapted. config ([`IA3Config`]): The configuration of the (IA)^3 model. adapter_name (`str`): The name of the adapter, defaults to `"default"`. low_cpu_mem_usage (`bool`, `optional`, defaults to `False`): Create empty adapter weights on meta device. Useful to speed up the loading process. Returns: `torch.nn.Module`: The (IA)^3 model. Example: ```py >>> from transformers import AutoModelForSeq2SeqLM, ia3Config >>> from peft import IA3Model, IA3Config >>> config = IA3Config( ... peft_type="IA3", ... task_type="SEQ_2_SEQ_LM", ... target_modules=["k", "v", "w0"], ... feedforward_modules=["w0"], ... ) >>> model = AutoModelForSeq2SeqLM.from_pretrained("t5-base") >>> ia3_model = IA3Model(config, model) ``` **Attributes**: - **model** ([`~transformers.PreTrainedModel`]) -- The model to be adapted. - **peft_config** ([`ia3Config`]): The configuration of the (IA)^3 model. ia3_strprefixc [5(a SSKnSSKJn [ 5(aSSKJn UR SS5nUR SS5nUR SS5n [U[5(aUR5n OUn U(a[U WRR5(adUR5n U RU RRU RRU R S .5 W"X!4SU 0U D6n U $U(a[U WRR 5(adUR5n U RU R"U R$R&U R$R(S .5 W"X!4SU 0U D6n U $[U[*RR,5(a[-X!4SU 0UD6n U $[U[*RR.5(a[/X!4SU 0UD6n U $[U [*RR05(a<US (a"[2R4"S 5 S=US 'Ul!4SU 0UD6n U $[U [85(a=US (d"[2R4"S 5 S=US 'Ul!4U SS.UD6n U $[;SUS35e)Nrr) Linear8bitLt) Linear4bitloaded_in_8bitFloaded_in_4bitis_feedforward)has_fp16_weights thresholdindex) compute_dtypecompress_statistics quant_typefan_in_fan_outzjfan_in_fan_out is set to True but the target module is `torch.nn.Linear`.
