Install OneFlow

System Requirements

Python 3.6, 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 -f https://release.oneflow.info oneflow==0.7.0+cu102

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-cuda10.2docker 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.zipunzip 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 buildcd 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
```
