OneFlow

OneFlow is a deep learning framework designed to be user-friendly, scalable and efficient. With OneFlow, it is easy to:

• program a model with PyTorch-like API
• scale a model to n-dimensional-parallel/distributed exectuion with the Global View API
• accelerate/deploy a model with the Static Graph Compiler.

Install OneFlow

System Requirements

• Linux. As for now, there is no pre-built release for macOS, Windows.

• Python 3.7, 3.8, 3.9, 3.10

• (Highly recommended) Upgrade pip

  python3 -m pip install --upgrade pip #--user
  

• CUDA Toolkit Linux x86_64 Driver

  • CUDA runtime is statically linked into OneFlow. OneFlow will work on a minimum supported driver, and any driver beyond. For more information, please refer to CUDA compatibility documentation.

  • Please upgrade your Nvidia driver to version 440.33 or above and install OneFlow for CUDA 10.2 if possible.

Install with Pip Package

• To install latest stable release of OneFlow with CUDA support:

  python3 -m pip install oneflow

• To install nightly release of OneFlow with CUDA support:

  python3 -m pip install --pre oneflow -f https://staging.oneflow.info/branch/master/cu102

• To install other available builds for different variants:

  • Stable

    python3 -m pip install --find-links https://release.oneflow.info oneflow==0.8.0+[PLATFORM]

  • Nightly

    python3 -m pip install --pre oneflow -f https://staging.oneflow.info/branch/master/[PLATFORM]
    

  • All available [PLATFORM]:

    Platform	CUDA Driver Version	Supported GPUs
    cu112	>= 450.80.02	GTX 10xx, RTX 20xx, A100, RTX 30xx
    cu102	>= 440.33	GTX 10xx, RTX 20xx
    cpu	N/A	N/A

• If you are in China, you could run this to have pip download packages from domestic mirror of pypi:

  python3 -m pip config set global.index-url https://pypi.tuna.tsinghua.edu.cn/simple
  

  For more information on this, please refer to pypi 镜像使用帮助

Use docker image

docker pull oneflowinc/oneflow:nightly-cuda10.2
docker pull oneflowinc/oneflow:nightly-cuda11.2

Build from Source

Clone Source Code

• Option 1: Clone source code from GitHub

  git clone https://github.com/Oneflow-Inc/oneflow --depth=1

• Option 2: Download from Aliyun

  If you are in China, please download OneFlow source code from: https://oneflow-public.oss-cn-beijing.aliyuncs.com/oneflow-src.zip

  curl https://oneflow-public.oss-cn-beijing.aliyuncs.com/oneflow-src.zip -o oneflow-src.zip
  unzip oneflow-src.zip

Build OneFlow

• Option 1: Build with Conda (recommended)

  Please refer to this repo

• Option 2: Build in docker container (recommended)

  • Pull the docker image:

    docker pull oneflowinc/manylinux2014_x86_64_cuda11.2

  • Follow the instructions in the bare metal build guide below.

• Option 3: Build on bare metal

  • Install dependencies (not required if you are using docker):

    • on Ubuntu 20.04, run:

      sudo apt install -y libopenblas-dev nasm g++ gcc python3-pip cmake autoconf libtool
      

    • on macOS, run:

      brew install nasm
      

  • In the root directory of OneFlow source code, run:

    mkdir build
    cd build
    

  • Config the project, inside build directory:

    • If you are in China

      run this to config for CUDA:

      cmake .. -C ../cmake/caches/cn/cuda.cmake
      

      run this to config for CPU-only:

      cmake .. -C ../cmake/caches/cn/cpu.cmake
      

    • If you are not in China

      run this to config for CUDA:

      cmake .. -C ../cmake/caches/international/cuda.cmake
      

      run this to config for CPU-only:

      cmake .. -C ../cmake/caches/international/cpu.cmake
      

  • Build the project, inside build directory, run:

    make -j$(nproc)
    

  • Add oneflow to your PYTHONPATH, inside build directory, run:

    source source.sh
    

    Please note that this change is not permanent.

  • Simple validation

    python3 -m oneflow --doctor
    

Troubleshooting

Please refer to troubleshooting for common issues you might encounter when compiling and running OneFlow.
