# <div align="center"><strong>OneFlow</strong></div>
## 简介
OneFlow 是一个深度学习框架，旨在**易用，可扩展且高效**。使用 OneFlow，很容易做到:

- 模型编程使用与 pytorch 类似的 API

- 使用 global API 将模型扩展到 n 维并行以便于分布式执行
- 使用静态图编译器加速/部署模型

## 安装 OneFlow-DCU

### System Requirements

- Linux.

- Python 3.7, 3.8, 3.9

- (**推荐**) Upgrade pip

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

###  Pip 安装

可以再光合[光合开发者社区](https://developer.hpccube.com/tool/#sdk) AI 生态包中获取最新的 Oneflow-DCU Release 版本（需对应 DCU Toolkit 版本与 python 版本）

```bash
python3 -m pip install oneflow-0.9+dtk2304.git.5be579-cp39-cp39-manylinux_2_17_x86_64.manylinux2014_x86_64.whl
```

### 使用镜像

提供 oneflow 0.9，dtk-23.04，python 3.9 的光源镜像

```
docker pull image.sourcefind.cn:5000/dcu/admin/base/oneflow:0.9.1-centos7.6-dtk-23.04-py39-latest
```

### 在 DCU 平台上源码编译（DTK-23.04，Python3.9）

- 拉取官方 CPU 镜像

  ```
  docker pull oneflowinc/manylinux2014_x86_64_cpu:latest
  ```

- 使用官网镜像建立 docker

  ```
  docker run -it --network=host --name=oneflow_compile --privileged --device=/dev/kfd --device=/dev/dri --ipc=host --shm-size=16G  --group-add video --cap-add=SYS_PTRACE --security-opt seccomp=unconfined -u root --ulimit stack=-1:-1 --ulimit memlock=-1:-1 -v `pwd`:/home oneflowinc/manylinux2014_x86_64_cpu:latest /bin/bash
  
  docker exec -it oneflow_compile /bin/bash
  ```

- 拉取 oneflow 代码

  ```
  git clone -b 0.9.1-rocm http://developer.hpccube.com/codes/aicomponent/oneflow.git
  ```

- 在[开发者社区](https://developer.hpccube.com/tool/#sdk) DCU Toolkit 中下载 DTK-23.04 解压至 /opt/ 路径下，并建立软链接

  ```
  ln -s /opt/dtk-23.04 /opt/rocm
  ```

- 导入环境变量以及安装必要依赖库

  ```

  yum install -y numactl libffi* openblas openblas-devel libibverbs-devel
  pip3 install -r dev-requirements.txt -i http://mirrors.aliyun.com/pypi/simple/ --trusted-host mirrors.aliyun.com
  ```

- cmake && make

  ```
  mkdir build && cd build
  cmake .. -DBUILD_CUDA=OFF -DBUILD_ROCM=ON -DONEFLOW=ON -DUSE_CLANG_FORMAT=OFF -DCMAKE_BUILD_TYPE=Release -DTHIRD_PARTY=ON -DTREAT_WARNINGS_AS_ERRORS=OFF -DTHIRD_PARTY_MIRROR=aliyun -DBUILD_HWLOC=OFF -DCMAKE_C_COMPILER=${ROCM_PATH}/llvm/bin/clang -DCMAKE_CXX_COMPILER=${ROCM_PATH}/llvm/bin/clang++ -DBUILD_TESTING=ON -DBUILD_RDMA=ON -DBUILD_PROFILER=ON
