flashmodels's Introduction

Flash Models

Flash Models is a library containing models accelerated by TorchAcc, a PyTorch training acceleration framework based on PyTorch/XLA.

Currently, it hosts common open-source large language models, with plans to expand to include models from other domains such as vision.

Setup

Clone the code and install the required dependencies:

# Start a container using the Docker image with TorchAcc.
sudo docker run  --gpus all --net host --ipc host --shm-size 10G -it --rm --cap-add=SYS_PTRACE registry.cn-hangzhou.aliyuncs.com/pai-dlc/acc:r2.3.0-cuda12.1.0-py3.10-nightly bash

# Clone the code and install the requirements.
git clone https://github.com/AlibabaPAI/FlashModels.git
cd ./FlashModels
pip install -r requirements.txt

Training

Each model supports two types of tasks:

training with TorchAcc
training without TorchAcc (Pytorch cuda native mode)

Here is an example of llama training tasks on a single worker with multiple devices (GPU or TPU):

Training with TorchAcc

./examples/run.sh \
    --model ./hf_models/config/llama-7b \
    --accelerator acc \
    --gc \
    --mbs 24 \
    --fsdp 8 \
    --bf16

Training without TorchAcc

./examples/run.sh \
    --model ./hf_models/config/llama-7b \
    --accelerator cuda \
    --gc \
    --mbs 8 \
    --fsdp 8 \
    --bf16
