• 2024/08/29: InternEvo supports streaming dataset of huggingface format. Add detailed instructions of data flow.

• 2024/04/17: InternEvo supports training model on NPU-910B cluster.

• 2024/01/17: To delve deeper into the InternLM series of models, please checkInternLM in our organization.

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.

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+cu118pip 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 toInstall Tutorial

Firstly, prepare training script astrain.py

For more detailed explanation, please refer toTraining Tutorial

Secondly, prepare data for training or fine-tuning.

Download dataset from huggingface, takeroneneldan/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 fromhttps://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 toUsage Tutorial

The content of configuration file is as7B_sft.py

For more detailed introduction, please refer toUsage Tutorial

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"

Please refer to theSystem Architecture document for architecture details.

We appreciate all the contributors for their efforts to improve and enhance InternEvo. Community users are highly encouraged to participate in the project. Please refer to the contribution guidelines for instructions on how to contribute to the project.

InternEvo codebase is an open-source project contributed by Shanghai AI Laboratory and researchers from different universities and companies. We would like to thank all the contributors for their support in adding new features to the project and the users for providing valuable feedback. We hope that this toolkit and benchmark can provide the community with flexible and efficient code tools for fine-tuning InternEvo and developing their own models, thus continuously contributing to the open-source community. Special thanks to the two open-source projects,flash-attention andColossalAI.
