MFTCoder: Boosting Code LLMs with Multitask Fine-Tuning (KDD2024)

Introduction

High Accuracy and efficiency Multi-task Fine-tuning framework for Code LLMs.

MFTCoder is an open-source project of CodeFuse for accurate and efficient Multi-task Fine-tuning(MFT) on Large Language Models(LLMs), especially on Code-LLMs(large language model for code tasks). Moreover, we open source Code LLM models and code-related datasets along with the MFTCoder framework.

In MFTCoder, we released two codebases for finetuning Large Language Models:

• MFTCoder-accelerate is a framework with accelerate and DeepSpeed/FSDP. All tech-stacks are open-source and vibrant. We highly recommend you try this framework and make your fintuning accurate and efficient.
• MFTCoder-atorch is based on the ATorch frameworks, which is a fast distributed training framework of LLM.

The aim of this project is to foster collaboration and share advancements in large language models, particularly within the domain of code development.

Frameworks

Highlights

:white_check_mark: Multi-task: Train models on multiple tasks while maintaining a balance between them. The models can even generalize to new, previously unseen tasks.

:white_check_mark: Multi-model: It integrates state-of-the-art open-source models such as gpt-neox, llama, llama-2, baichuan, Qwen, chatglm2, and more. (These finetuned models will be released in the near future.)

:white_check_mark: Multi-framework: It provides support for both Accelerate (with Deepspeed and FSDP) and ATorch

:white_check_mark: Efficient fine-tuning: It supports LoRA, QLoRA as well as Full-parameters training, enabling fine-tuning of large models with minimal resources. The training speed meets the demands of almost all fine-tuning scenarios.

The main components of this project include:

• Support for both SFT (Supervised FineTuning) and MFT (Multi-task FineTuning). The current MFTCoder achieves data balance among multiple tasks, and future releases will achieve a balance between task difficulty and convergence speed during training.
• Support for QLoRA instruction fine-tuning, LoRA fine-tuning as well as Full-parameters fine-tuning.
• Support for most mainstream open-source large models, particularly those relevant to Code-LLMs, such as DeepSeek-coder, Mistral, Mixtral, Chatglm3, Code-LLaMA, Starcoder, Codegeex2, Qwen, GPT-Neox, and more.
• Support for weight merging between the LoRA adaptor and base models, simplifying the inference process.
• Release of 2 high-quality code-related instruction fine-tuning datasets: Evol-instruction-66k and CodeExercise-Python-27k.
• Release of many Code LLMs, please refer to organizations: codefuse-ai on huggingface or codefuse-ai on modelscope.

Requirements

To begin, ensure that you have successfully installed CUDA (version >= 11.4, preferably 12.1) along with the necessary drivers. Additionally, make sure you have installed torch (version >= 2.1.0).

Next, we have provided an init_env.sh script to simplify the installation of required packages. Execute the following command to run the script:

sh init_env.sh

We highly recommend training with flash attention(version >= 2.3.0), please refer to the following link for installation instructions: https://github.com/Dao-AILab/flash-attention

Training

As mentioned above, we open source two training frameworks. You could refer to their own READMEs for more details as followed.

If you are familiar with open source transformers, DeepSpeed or FSDP, we highly recommend you try:

🚀🚀 MFTCoder-accelerate: Accelerate + Deepspeed/FSDP Codebase for MFT(Multi-task Finetuning)

If you want to explore some new framework like atorch, you could check:

🚀 MFTCoder-atorch: Atorch Codebase for MFT(Multi-task Finetuning)

Models

We are excited to release the following two CodeLLMs trained by MFTCoder, now available on both HuggingFace and ModelScope:

Datasets

We are also pleased to release two code-related instruction datasets, meticulously selected from a range of datasets to facilitate multitask training. Moving forward, we are committed to releasing additional instruction datasets covering various code-related tasks.
