📝 Introduction

🍲 ms-swift is an official framework provided by the ModelScope community for fine-tuning and deploying large language models and multi-modal large models. It currently supports the training (pre-training, fine-tuning, human alignment), inference, evaluation, quantization, and deployment of over 400 large models and 100+ multi-modal large models. These large language models (LLMs) include models such as Qwen2.5, Llama3.2, GLM4, Internlm2.5, Yi1.5, Mistral, DeepSeek, Baichuan2, Gemma2, and TeleChat2. The multi-modal LLMs include models such as Qwen2-VL, Qwen2-Audio, Llama3.2-Vision, Llava, InternVL2.5, MiniCPM-V-2.6, GLM4v, Xcomposer2.5, Yi-VL, DeepSeek-VL2, Phi3.5-Vision, and GOT-OCR2.

🍔 In addition, ms-swift gathers the latest training technologies, including LoRA, QLoRA, Llama-Pro, LongLoRA, GaLore, Q-GaLore, LoRA+, LISA, DoRA, FourierFt, ReFT, UnSloth, and Liger. ms-swift supports accelerating the inference, evaluation, and deployment modules using vLLM and LMDeploy. To help researchers and developers fine-tune and apply large models more easily, ms-swift also provides a Gradio-based Web-UI interface and a wealth of best practices.

🚀 Quick Start

10 minutes of self-cognition fine-tuning of Qwen2.5-7B-Instruct on a single 3090 GPU:

Command Line Interface

    --lora_rank 8 \
    --lora_alpha 32 \
    --target_modules all-linear \
    --gradient_accumulation_steps 16 \

    --warmup_ratio 0.05 \
    --dataloader_num_workers 4 \
    --model_author swift \
    --model_name swift-robot

After training is complete, use the following command to perform inference with the trained weights. The --adapters option should be replaced with the last checkpoint folder generated from the training. Since the adapters folder contains the parameter files from the training, there is no need to specify --model or --system separately.

# Using an interactive command line for inference.
CUDA_VISIBLE_DEVICES=0 \
swift infer \
    --adapters output/vx-xxx/checkpoint-xxx \
    --stream true

# merge-lora and use vLLM for inference acceleration
CUDA_VISIBLE_DEVICES=0 \
swift infer \
    --adapters output/vx-xxx/checkpoint-xxx \
    --stream true \
    --merge_lora true \
    --infer_backend vllm \
    --max_model_len 8192

Web-UI

The Web-UI is a zero-threshold training and deployment interface solution based on Gradio interface technology. For more details, you can check here.

Using Python

ms-swift also supports training and inference using Python. Below is pseudocode for training and inference. For more details, you can refer to here.

Training:

# Retrieve the model and template, and add a trainable LoRA module
model, tokenizer = get_model_tokenizer(model_id_or_path, ...)
template = get_template(model.model_meta.template, tokenizer, ...)
model = Swift.prepare_model(model, lora_config)

# Download and load the dataset, and encode the text into tokens
train_dataset, val_dataset = load_dataset(dataset_id_or_path, ...)
train_dataset = EncodePreprocessor(template=template)(train_dataset, num_proc=num_proc)
val_dataset = EncodePreprocessor(template=template)(val_dataset, num_proc=num_proc)

# Train the model
trainer = Seq2SeqTrainer(
    model=model,
    args=training_args,
    data_collator=template.data_collator,
    train_dataset=train_dataset,
    eval_dataset=val_dataset,
    template=template,
)
trainer.train()

Inference:

# Perform inference using the native PyTorch engine
engine = PtEngine(model_id_or_path, adapters=[lora_checkpoint])
infer_request = InferRequest(messages=[{'role': 'user', 'content': 'who are you?'}])
request_config = RequestConfig(max_tokens=max_new_tokens, temperature=temperature)

resp_list = engine.infer([infer_request], request_config)
print(f'response: {resp_list[0].choices[0].message.content}')
