For example, to load a PEFT adapter model for causal language modeling: The configuration classes stores the configuration of a PeftModel, PEFT adapter models, and the configurations of PrefixTuning, PromptTuning, and PromptEncoder. , r=lora_alpha=16) and adjust based on training results. If a single integer is passed, PEFT will transform only the layer at Mar 22, 2023 · peft_model = get_peft_model(model, peft_config=peft_config). OLoRA utilizes QR decomposition to initialize the LoRA adapters. class LoraRuntimeConfig: """ 🤗 PEFT: State-of-the-art Parameter-Efficient Fine-Tuning. To load and use a PEFT adapter model from 🤗 Transformers, make sure the Hub repository or local directory contains an adapter_config. PEFT offers parameter-efficient methods for finetuning large pretrained models. This is the base configuration class for PEFT adapter models. peft_config (Dict, defaults to None) — The PEFT configuration to use for training. Recently, Parameter-Efficient Fine-Tuning (PEFT) methods have achieved strong task performance while updating much fewer parameters than full model fine-tuning (FFT). The appropriate configuration type is determined by the peft_type argument. py at main · huggingface/peft Oct 22, 2023 · 上記のように、peftを使用してLLMをファインチューニングする際には、1度読み込んだモデルをget_peft_modelという関数にモデルと peftの指定を行ったconfigを追加しないと行けません。 Sep 27, 2024 · Practical Tips for Using LoraConfig. to(device=device) 이후의 과정은 huggingface의 pipeline과 동일하므로 생략하겠다. from peft. The layer indexes to transform, is this argument is specified, PEFT will transform only the layers indexes that are specified inside this list. Even if you don't see a model listed below, you can manually configure the model config to enable PEFT for a model. #gpt Jul 6, 2024 · trainer = SFTTrainer(model=model_name, # model to train train_dataset=dataset, # the training dataset eval_dataset=eval_dataset, # the evaluation dataset peft_config=peft_config, # from LoRA . SEQ_2_SEQ_LM, inference_mode= False, r= 8, lora_alpha= 32, lora_dropout= 0. Jan 28, 2023 · Large pretrained language models are widely used in downstream NLP tasks via task-specific fine-tuning, but such procedures can be costly. Additive Quantization of Language Models is a Large Language Models compression method. 19%のみを peft_type (Union[~peft. However, it is non-trivial to make informed design choices on the PEFT configurations peft_config (dict, defaults to None) — The PEFT configuration to use for training. For the bigscience/mt0-large model May 26, 2023 · PeftModelを作成するには、get_peft_model関数でベースモデルとpeft_configをラップします。モデルでトレーニング可能なパラメーター数の感覚を掴むには、print_trainable_parametersメソッドを使用します。このケースでは、モデルのパラメーターの0. json文件和adapter权重，如上例所示。然后，您可以使用AutoModelFor类加载PEFT adapter模型。例如，要为因果语言建模加载一个PEFT adapter模型： 指定PEFT模型id Jul 31, 2023 · Parameter Efficient Fine-Tuning (PEFT) represents a paradigm shift in the way large language models (LLMs) are adapted to specific tasks. . The PEFT library is designed to help you quickly train large models on free or low-cost GPUs, and in this tutorial, you’ll learn how to setup a configuration to apply a PEFT method to a pretrained base model for training. compute_metrics (Callable[[EvalPrediction], Dict], optional) — The function to use to compute the metrics. warn( f"peft config has already set base model revision to {peft_config. model_id (str or os. Dec 13, 2024 · You can use PEFT recipes via the NeMo Run CLI (See here for more details). For the bigscience/mt0-large model, you're only training 0. 要从huggingface的Transformers库中加载并使用PEFTadapter模型，请确保Hub仓库或本地目录包含一个adapter_config. Unlike full fine-tuning, where all model parameters are Nov 27, 2023 · # Load the configuration for the Peft model from a pre-trained version peft_config = PeftConfig. A configuration stores important parameters that specify how a particular PEFT method should be applied. config import PeftConfig. e. utils. - peft/src/peft/config. Then you can load the PEFT adapter model using the AutoModelFor class. If you pass a PEFT configuration, the model will be wrapped in a PEFT model. This provides a quick and easy way to launch training jobs when you do not need to override any configuration from the default recipes. if peft_config. , it mutates the weights before performing any training on them. revision is not None and peft_config. PeftType, str]) — The type of Peft method to use. This method loads the configuration of your adapter model from a set of kwargs. Feb 10, 2023 · Creating config corresponding to the PEFT method; peft_config = LoraConfig( task_type=TaskType. from_pretrained(peft_model_id) # Load the base causal language model using the configuration peft_type (Union[~peft. json file and the adapter weights, as shown in the example image above. 1) Wrapping base 🤗 Transformers model by calling get_peft_model Prepare a model for training with a PEFT method such as LoRA by wrapping the base model and PEFT configuration with get_peft_model. revision != revision: warnings. For example, take a look at the following LoraConfig for applying LoRA and PromptEncoderConfig for applying p-tuning (these configuration files are already JSON-serialized). Sep 18, 2024 · Parameter-efficient fine-tuning (PEFT) modifies a subset of parameters in pre-trained neural networks, rather than updating all model parameters. config. Traditional fine-tuning methods can be computationally intensive, requiring significant resources and storage. Dec 6, 2024 · Prepare a model for training with a PEFT method such as LoRA by wrapping the base model and PEFT configuration with get_peft_model. It contains all the methods that are common to all PEFT adapter models. AQLM quantization. A path to a directory containing a PEFT configuration file saved using the save_pretrained method (. ; Monitor For detailed instruction on using PiSSA, please follow these instructions. The traditional paradigm is to finetune all of a model’s parameters for each downstream task, but this is becoming exceedingly costly and impractical because of the enormous number of parameters in models today. Can be either: A string, the model id of a PEFT configuration hosted inside a model repo on the Hugging Face Hub. Start with Default Values: If you’re new to LoRA, begin with common settings (e. revision}, overwriting with revision {revision}" Quicktour. Must take a EvalPrediction and return a dictionary string to metric values. LoRA and DoRA are registered as factory classes, so you can specify peft=<lora/dora/none> directly in the terminal. /my_peft_config_directory/). It quantizes multiple weights together and takes advantage of interdependencies between them. OLoRA.
