Introduction

InternEvo is an open-sourced lightweight training framework aims to support model pre-training without the need for extensive dependencies. With a single codebase, it supports pre-training on large-scale clusters with thousands of GPUs, and fine-tuning on a single GPU while achieving remarkable performance optimizations. InternEvo achieves nearly 90% acceleration efficiency during training on 1024 GPUs.

Based on the InternEvo training framework, we are continually releasing a variety of large language models, including the InternLM-7B series and InternLM-20B series, which significantly outperform numerous renowned open-source LLMs such as LLaMA and other leading models in the field.

Installation

First, install the specified versions of torch, torchvision, torchaudio, and torch-scatter. For example:

pip install --extra-index-url https://download.pytorch.org/whl/cu118 torch==2.1.0+cu118 torchvision==0.16.0+cu118 torchaudio==2.1.0+cu118
pip install torch-scatter -f https://data.pyg.org/whl/torch-2.1.0+cu118.html

Install InternEvo:

pip install InternEvo

Install flash-attention (version v2.2.1):

If you need to use flash-attention to accelerate training, and it is supported in your environment, install as follows:

pip install flash-attn==2.2.1

For more detailed information about installation environment or source code installation, please refer to Install Tutorial

Quick Start

Train Script

Firstly, prepare training script as train.py

For more detailed explanation, please refer to Training Tutorial

Data Preparation

Secondly, prepare data for training or fine-tuning.

Download dataset from huggingface, take roneneldan/TinyStories dataset as example:

huggingface-cli download --repo-type dataset --resume-download "roneneldan/TinyStories" --local-dir "/mnt/petrelfs/hf-TinyStories"

Achieve tokenizer to local path. For example, download special_tokens_map.json、tokenizer.model、tokenizer_config.json、tokenization_internlm2.py and tokenization_internlm2_fast.py from https://huggingface.co/internlm/internlm2-7b/tree/main to local /mnt/petrelfs/hf-internlm2-tokenizer .

Then modify configuration file as follows:

TRAIN_FOLDER = "/mnt/petrelfs/hf-TinyStories"
data = dict(
    type="streaming",
    tokenizer_path="/mnt/petrelfs/hf-internlm2-tokenizer",
)

For other type dataset preparation, please refer to Usage Tutorial

Configuration File

The content of configuration file is as 7B_sft.py

For more detailed introduction, please refer to Usage Tutorial

Train Start

Training can be started on slurm or torch distributed environment.

On slurm, using 2 nodes and 16 cards, the command is as follows:

$ srun -p internllm -N 2 -n 16 --ntasks-per-node=8 --gpus-per-task=1 python train.py --config ./configs/7B_sft.py

On torch, using 1 node and 8 cards, the command is as follows:

$ torchrun --nnodes=1 --nproc_per_node=8 train.py --config ./configs/7B_sft.py --launcher "torch"

System Architecture

Please refer to the System Architecture document for architecture details.
