Introduction

CodeFuse-MFTCoder is an open-source project of CodeFuse for multitasking Code-LLMs(large language model for code tasks), which includes models, datasets, training codebases and inference guides. In MFTCoder, we released two codebases for finetuning Large Language Models:

  • mft_peft_hf is based on the HuggingFace Accelerate and deepspeed framework.
  • mft_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.

Highlights

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

βœ… 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.)

βœ… Multi-framework: It provides support for both HuggingFace Accelerate (with deepspeed) and ATorch.

βœ… Efficient fine-tuning: It supports LoRA and QLoRA, 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, as well as LoRA fine-tuning.
  • Support for most mainstream open-source large models, particularly those relevant to Code-LLMs, such as 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 2 models: CodeFuse-13B and CodeFuse-CodeLlama-34B.

Requirements

To begin, ensure that you have successfully installed CUDA (version >= 11.4, preferably 11.7) along with the necessary drivers. Additionally, make sure you have installed torch (version 2.0.1).

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

If you require flash attention, please refer to the following link for installation instructions: https://github.com/Dao-AILab/flash-attention

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.

Dataset Introduction
⭐ Evol-instruction-66k Based on open-evol-instruction-80k, filter out low-quality, repeated, and similar instructions to HumanEval, thus get high-quality code instruction dataset.
⭐ CodeExercise-Python-27k python code exercise instruction dataset generated by chatgpt
