+ pytorch 版本大于 2.4.1 && dtk 版本大于 25.04 推荐使用 fastpt 不转码编译。

### 2.1 使用pip方式安装

d2go whl 包下载目录:[光和开发者社区](https://download.sourcefind.cn:65024/4/main),选择对应的 pytorch 版本和 python 版本下载对应 d2go 的 whl 包: 

```shell
pip install torch* # 下载torch的whl包
pip install fastpt* --no-deps # 下载fastpt的whl包
source  /usr/local/bin/fastpt -E
pip install d2go* # # 下载的 d2go-fastpt 的whl包

#### 2.2.1 编译环境准备

提供基于 fastpt 不转码编译:

1. 基于光源 pytorch 基础镜像环境:镜像下载地址:[光合开发者社区](https://sourcefind.cn/#/image/dcu/pytorch),根据 pytorch、python、dtk 及系统下载对应的镜像版本。
2. 基于现有 python 环境:安装 pytorch,fastpt whl 包下载目录:[光合开发者社区](https://sourcefind.cn/#/image/dcu/pytorch),根据 python、dtk 版本,下载对应 pytorch 的 whl 包。安装命令如下:

```shell
pip install torch* # 下载torch的whl包
pip install fastpt* --no-deps # 下载fastpt的whl包, 安装顺序,先安装torch,后安装fastpt
pip install setuptools==59.5.0 wheel pytest scikit-learn

- 提供2种源码编译方式(进入 d2go 目录):
  - 源码编译安装:

    ```bash
    source /usr/local/bin/fastpt -C
    python -m pip install 'git+https://github.tbedu.top/https://github.com/facebookresearch/detectron2.git'
    python -m pip install 'git+https://github.tbedu.top/https://github.com/facebookresearch/mobile-vision.git'

    python setup.py develop
    python setup.py install
    ```
  - whl 包构建安装:

    ```bash
    source /usr/local/bin/fastpt -C

    python setup.py bdist_wheel # 该指令用于编译whl包,执行该指令时不必执行前两个指令
    pip install dist/d2go-0.0.1b20250528-py3-none-any.whl
    ```

#### 2.2.3 注意事项

+ ROCM_PATH 为 dtk 的路径,默认为 /opt/dtk;
+ 在 pytorch2.5.1 环境下编译需要支持 c++17 语法,打开setup.py文件,把文件中的 -std=c++14 修改为 -std=c++17。
