📝 Introduction

SWIFT (Scalable lightWeight Infrastructure for Fine-Tuning) is an extensible framework designed to facilitate lightweight model fine-tuning and inference. It integrates implementations for various efficient fine-tuning methods, by embracing approaches that is parameter-efficient, memory-efficient, and time-efficient. SWIFT integrates seamlessly into ModelScope ecosystem and offers the capabilities to finetune various models, with a primary emphasis on LLMs and vision models. Additionally, SWIFT is fully compatible with PEFT, enabling users to leverage the familiar Peft interface to finetune ModelScope models.

Currently supported approaches (and counting):

  1. 🔥LoRA: LORA: LOW-RANK ADAPTATION OF LARGE LANGUAGE MODELS
  2. 🔥LoRA+: LoRA+: Efficient Low Rank Adaptation of Large Models
  3. 🔥LLaMA PRO: LLAMA PRO: Progressive LLaMA with Block Expansion
  4. 🔥SCEdit: SCEdit: Efficient and Controllable Image Diffusion Generation via Skip Connection Editing < arXiv | Project Page >
  5. 🔥NEFTune: Noisy Embeddings Improve Instruction Finetuning
  6. QA-LoRA:Quantization-Aware Low-Rank Adaptation of Large Language Models.
  7. LongLoRA: Efficient Fine-tuning of Long-Context Large Language Models
  8. ROME: Rank-One Editing of Encoder-Decoder Models
  9. Adapter: Parameter-Efficient Transfer Learning for NLP
  10. Prompt Tuning: Visual Prompt Tuning
  11. Side: Side-Tuning: A Baseline for Network Adaptation via Additive Side Networks
  12. Res-Tuning: Res-Tuning: A Flexible and Efficient Tuning Paradigm via Unbinding Tuner from Backbone < arXiv | Project Page | Usage >
  13. All tuners offered on PEFT, like IA3, AdaLoRA

Key features:

  1. By integrating the ModelScope library, models can be readily obtained via a model-id.
  2. Tuners provided by SWIFT can be combined to allow exploration of multiple tuners on a model for best result.
  3. Support calling activate_adapter or deactivate_adapter or set_active_adapters to activate/deactivate tuners. User can inference with one model and multiple tuners in different threads independently.
  4. Support training and inference with scripts/CLI，meanwhile support inference with Web-UI.
  5. Support model deployment(vllm/chatglm.cpp/xinference)，Check Official documentation for details.

Users can check the documentation of SWIFT to get detail tutorials.

🔥SCEdit

SCEdit is an efficient generative fine-tuning framework proposed by Alibaba TongYi Vision Intelligence Lab. This framework enhances the fine-tuning capabilities for text-to-image generation downstream tasks and enables quick adaptation to specific generative scenarios, saving 30%-50% of training memory costs compared to LoRA. Furthermore, it can be directly extended to controllable image generation tasks, requiring only 7.9% of the parameters that ControlNet needs for conditional generation and saving 30% of memory usage. It supports various conditional generation tasks including edge maps, depth maps, segmentation maps, poses, color maps, and image completion.

🛠️ Installation

SWIFT is running in Python environment. Please make sure your python version is higher than 3.8.

  • Install SWIFT by the pip command:
# full ability
pip install ms-swift[all] -U
# only use llm
pip install ms-swift[llm] -U
# only use aigc
pip install ms-swift[aigc] -U
# only use adapters
pip install ms-swift -U
  • Install SWIFT by source code(for running sft/infer examples), please run:
git clone https://github.com/modelscope/swift.git
cd swift
pip install -e .[llm]

SWIFT requires torch>=1.13.

  • Use SWIFT in our docker image:
docker pull registry.cn-hangzhou.aliyuncs.com/modelscope-repo/modelscope:ubuntu20.04-cuda11.8.0-py38-torch2.0.1-tf2.13.0-1.9.1

🚀 Getting Started

SWIFT supports multiple tuners, as well as tuners provided by PEFT. To use these tuners, simply call:

from swift import Swift, LoRAConfig
config = LoRAConfig(...)
model = Swift.prepare_model(model, config, extra_state_keys=['...'])

The code snippet above initialized the tuner randomly. The input model is an instance of torch.nn.Module, the config is a subclass instance of SwiftConfig or PeftConfig. extra_state_keys is the extra module weights(like the linear head) to be trained and stored in the output dir.

You may combine multiple tuners by:

from swift import Swift, LoRAConfig, PromptConfig
model = Swift.prepare_model(model, {'lora': LoRAConfig(...), 'prompt': PromptConfig(...)})

Call save_pretrained and push_to_hub after finetuning:

from swift import push_to_hub
model.save_pretrained('some-output-folder')
push_to_hub('my-group/some-repo-id-modelscope', 'some-output-folder', token='some-ms-token')

Assume my-group/some-repo-id-modelscope is the model-id in the hub, and some-ms-token is the token for uploading.

Using the model-id to do later inference:

from swift import Swift
model = Swift.from_pretrained(model, 'my-group/some-repo-id-modelscope')

Here shows a runnable example:

import os
import tempfile

# Please install modelscope by `pip install modelscope`
from modelscope import Model

from swift import LoRAConfig, SwiftModel, Swift, push_to_hub

tmp_dir = tempfile.TemporaryDirectory().name
if not os.path.exists(tmp_dir):
    os.makedirs(tmp_dir)


model = Model.from_pretrained('modelscope/Llama-2-7b-ms', device_map='auto')
lora_config = LoRAConfig(target_modules=['q_proj', 'k_proj', 'v_proj'])
model: SwiftModel = Swift.prepare_model(model, lora_config)
# Do some finetuning here
model.save_pretrained(tmp_dir)

push_to_hub('my-group/swift_llama2', output_dir=tmp_dir)
model = Model.from_pretrained('modelscope/Llama-2-7b-ms', device_map='auto')
model = SwiftModel.from_pretrained(model, 'my-group/swift_llama2', device_map='auto')

This is a example that uses transformers for model creation uses SWIFT for efficient tuning.

from swift import Swift, LoRAConfig, AdapterConfig, PromptConfig
from transformers import AutoModelForImageClassification

# init vit model
model = AutoModelForImageClassification.from_pretrained("google/vit-base-patch16-224")

# init lora tuner config
lora_config = LoRAConfig(
    r=10,  # the rank of the LoRA module
    target_modules=['query', 'key', 'value'],  # the modules to be replaced with the end of the module name
    merge_weights=False  # whether to merge weights
)

# init adapter tuner config
adapter_config = AdapterConfig(
    dim=768,  # the dimension of the hidden states
    hidden_pos=0,  # the position of the hidden state to passed into the adapter
    target_modules=r'.*attention.output.dense$',  # the modules to be replaced with regular expression
    adapter_length=10  # the length of the adapter length
)

# init prompt tuner config
prompt_config = PromptConfig(
    dim=768,  # the dimension of the hidden states
    target_modules=r'.*layer\.\d+$',  # the modules to be replaced with regular expression
    embedding_pos=0,    # the position of the embedding tensor
    prompt_length=10,   # the length of the prompt tokens
    attach_front=False  # Whether prompt is attached in front of the embedding
)

# create model with swift. In practice, you can use any of these tuners or a combination of them.
model = Swift.prepare_model(model, {"lora_tuner": lora_config, "adapter_tuner": adapter_config, "prompt_tuner": prompt_config})

# get the trainable parameters of model
model.get_trainable_parameters()
# 'trainable params: 838,776 || all params: 87,406,432 || trainable%: 0.9596273189597764'

You can use the features offered by Peft in SWIFT:

from swift import LoraConfig, Swift
from peft import TaskType
lora_config = LoraConfig(target_modules=['query', 'key', 'value'], task_type=TaskType.CAUSAL_LM)
model_wrapped = Swift.prepare_model(model, lora_config)

# or call from_pretrained to load weights in the modelhub
model_wrapped = Swift.from_pretrained(model, 'some-id-in-the-modelscope-modelhub')

The saving strategy between Swift tuners and Peft tuners are slightly different. You can name a tuner by:

model = Swift.prepare_model(model, {'default': LoRAConfig(...)})
model.save_pretrained('./output')

In the output dir, you will have a dir structure like this:

output
    |-- default
        |-- adapter_config.json
        |-- adapter_model.bin
    |-- adapter_config.json
    |-- adapter_model.bin

The config/weights stored in the output dir is the config of extra_state_keys and the weights of it. This is different from PEFT, which stores the weights and config of the default tuner.
