PyTorch Cluster是一个小型的扩展库,其中包含了高度优化的图聚类算法,用于在PyTorch中使用。该包包括以下聚类算法:Graclus,Voxel Grid Pooling,迭代最远点采样,k-NN和Radius图生成,基于最近点的聚类,随机游走采样等。DAS软件栈中的PyTorch Cluster版本,不仅保证了组件核心功能在DCU加速卡的可用性,还针对DCU特有的硬件架构进行了深度定制优化。这使得开发者能够以极低的成本,轻松实现应用程序在DCU加速卡上的快速迁移和性能提升。目前支持Pytorch1.13 Pyotrch2.1 Pytorch2.3

## 安装

### 使用pip方式安装
pytorch-cluster whl包下载目录:[http://10.6.10.68:8000/customized/torch-cluster/dtk2310](http://10.6.10.68:8000/customized/torch-cluster/dtk2310),目前只提供有python3.8版本的whl包。
```shell
pip install torch_cluster* (下载的torch_cluster的whl包)
```
### 使用源码编译方式安装

#### 编译环境准备
- 安装相关依赖
```shell
pip install numpy
pip install 'urllib3==1.26.14' 
pip install pytest
pip install wheel 
```
- 在首页 | 光合开发者社区下载 dtk23.10 解压至 /opt/ 路径下,并建立软链接
```shell
cd /opt && ln -s dtk-23.10 dtk
source /opt/dtk/env.sh
```
- 安装pytorch,pytorch whl包下载目录:[http://10.6.10.68:8000/debug/pytorch/dtk23.10/hipify/](http://10.6.10.68:8000/debug/pytorch/dtk23.10/hipify/),根据python、dtk版本,下载对应pytorch的whl包。安装命令如下:
```shell
pip install torch* (下载的torch的whl包)
```
#### 源码编译安装
```shell
git clone -b 1.6.0-release http://developer.hpccube.com/codes/aicomponent/torch-cluster.git

export FORCE_CUDA=1 or python pymap_script.py /path/to/pytorch_cluster(二选一,该操作是把HIP(CUDA)代码编译进去)

## Known Issue
完成安装进行单测时,会报错ImportError: Could not find module '_version_cpu' ~,在根目录/下查找一下,然后把库文件目录添加一下软链接即可。
