Built on top of the [🤗 Transformers](https://github.com/huggingface/transformers) ecosystem, TRL supports a variety of model architectures and modalities, and can be scaled-up across various hardware setups. ## Highlights - **Trainers**: Various fine-tuning methods are easily accessible via trainers like [`SFTTrainer`](https://huggingface.co/docs/trl/sft_trainer), [`GRPOTrainer`](https://huggingface.co/docs/trl/grpo_trainer), [`DPOTrainer`](https://huggingface.co/docs/trl/dpo_trainer), [`RewardTrainer`](https://huggingface.co/docs/trl/reward_trainer) and more. - **Efficient and scalable**: - Leverages [🤗 Accelerate](https://github.com/huggingface/accelerate) to scale from single GPU to multi-node clusters using methods like [DDP](https://pytorch.org/tutorials/intermediate/ddp_tutorial.html) and [DeepSpeed](https://github.com/deepspeedai/DeepSpeed). - Full integration with [🤗 PEFT](https://github.com/huggingface/peft) enables training on large models with modest hardware via quantization and LoRA/QLoRA. - Integrates [🦥 Unsloth](https://github.com/unslothai/unsloth) for accelerating training using optimized kernels. - **Command Line Interface (CLI)**: A simple interface lets you fine-tune with models without needing to write code. ## Installation ### Python Package Install the library using `pip`: ```bash pip install trl ``` ### From source If you want to use the latest features before an official release, you can install TRL from source: ```bash pip install git+https://github.com/huggingface/trl.git ``` ### Repository If you want to use the examples you can clone the repository with the following command: ```bash git clone https://github.com/huggingface/trl.git ``` ## Quick Start For more flexibility and control over training, TRL provides dedicated trainer classes to post-train language models or PEFT adapters on a custom dataset. Each trainer in TRL is a light wrapper around the 🤗 Transformers trainer and natively supports distributed training methods like DDP, DeepSpeed ZeRO, and FSDP. ### `SFTTrainer` Here is a basic example of how to use the [`SFTTrainer`](https://huggingface.co/docs/trl/sft_trainer): ```python from trl import SFTTrainer from datasets import load_dataset dataset = load_dataset("trl-lib/Capybara", split="train") trainer = SFTTrainer( model="Qwen/Qwen2.5-0.5B", train_dataset=dataset, ) trainer.train() ``` ### `GRPOTrainer` [`GRPOTrainer`](https://huggingface.co/docs/trl/grpo_trainer) implements the [Group Relative Policy Optimization (GRPO) algorithm](https://huggingface.co/papers/2402.03300) that is more memory-efficient than PPO and was used to train [Deepseek AI's R1](https://huggingface.co/deepseek-ai/DeepSeek-R1). ```python from datasets import load_dataset from trl import GRPOTrainer dataset = load_dataset("trl-lib/tldr", split="train") # Dummy reward function: count the number of unique characters in the completions def reward_num_unique_chars(completions, **kwargs): return [len(set(c)) for c in completions] trainer = GRPOTrainer( model="Qwen/Qwen2-0.5B-Instruct", reward_funcs=reward_num_unique_chars, train_dataset=dataset, ) trainer.train() ``` ### `DPOTrainer` [`DPOTrainer`](https://huggingface.co/docs/trl/dpo_trainer) implements the popular [Direct Preference Optimization (DPO) algorithm](https://huggingface.co/papers/2305.18290) that was used to post-train [Llama 3](https://huggingface.co/papers/2407.21783) and many other models. Here is a basic example of how to use the `DPOTrainer`: ```python from datasets import load_dataset from transformers import AutoModelForCausalLM, AutoTokenizer from trl import DPOConfig, DPOTrainer model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2.5-0.5B-Instruct") tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-0.5B-Instruct") dataset = load_dataset("trl-lib/ultrafeedback_binarized", split="train") training_args = DPOConfig(output_dir="Qwen2.5-0.5B-DPO") trainer = DPOTrainer( model=model, args=training_args, train_dataset=dataset, processing_class=tokenizer ) trainer.train() ``` ### `RewardTrainer` Here is a basic example of how to use the [`RewardTrainer`](https://huggingface.co/docs/trl/reward_trainer): ```python from trl import RewardConfig, RewardTrainer from datasets import load_dataset from transformers import AutoModelForSequenceClassification, AutoTokenizer tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-0.5B-Instruct") model = AutoModelForSequenceClassification.from_pretrained( "Qwen/Qwen2.5-0.5B-Instruct", num_labels=1 ) model.config.pad_token_id = tokenizer.pad_token_id dataset = load_dataset("trl-lib/ultrafeedback_binarized", split="train") training_args = RewardConfig(output_dir="Qwen2.5-0.5B-Reward", per_device_train_batch_size=2) trainer = RewardTrainer( args=training_args, model=model, processing_class=tokenizer, train_dataset=dataset, ) trainer.train() ``` ## Command Line Interface (CLI) You can use the TRL Command Line Interface (CLI) to quickly get started with post-training methods like Supervised Fine-Tuning (SFT) or Direct Preference Optimization (DPO): **SFT:** ```bash trl sft --model_name_or_path Qwen/Qwen2.5-0.5B \ --dataset_name trl-lib/Capybara \ --output_dir Qwen2.5-0.5B-SFT ``` **DPO:** ```bash trl dpo --model_name_or_path Qwen/Qwen2.5-0.5B-Instruct \ --dataset_name argilla/Capybara-Preferences \ --output_dir Qwen2.5-0.5B-DPO ``` Read more about CLI in the [relevant documentation section](https://huggingface.co/docs/trl/main/en/clis) or use `--help` for more details. ## Development If you want to contribute to `trl` or customize it to your needs make sure to read the [contribution guide](https://github.com/huggingface/trl/blob/main/CONTRIBUTING.md) and make sure you make a dev install: ```bash git clone https://github.com/huggingface/trl.git cd trl/ pip install -e .[dev] ``` ## Citation ```bibtex @misc{vonwerra2022trl, author = {Leandro von Werra and Younes Belkada and Lewis Tunstall and Edward Beeching and Tristan Thrush and Nathan Lambert and Shengyi Huang and Kashif Rasul and Quentin Gallouédec}, title = {TRL: Transformer Reinforcement Learning}, year = {2020}, publisher = {GitHub}, journal = {GitHub repository}, howpublished = {\url{https://github.com/huggingface/trl}} } ``` ## License This repository's source code is available under the [Apache-2.0 License](LICENSE).
