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

Platform	CUDA Driver Version	Supported GPUs
cu112	>= 450.80.02	GTX 10xx, RTX 20xx, A100, RTX 30xx

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
