## 准备数据：
使用连接下载 **ShapeNet** 数据集：[下载地址](https://shapenet.cs.stanford.edu/media/shapenetcore_partanno_segmentation_benchmark_v0_normal.zip) 

下载完成后解压到 `data/shapenetcore_partanno_segmentation_benchmark_v0_normal`

## 训练：

```bash
python train.py
```

## 实验结果：


| Models                   | Accuracy | cat.mIOU | ins.mIOU |
| ------------------------ | -------------- | ------------ | ------------ |
| Point Transformer (paper)      |       None      |     0.837    |    0.866     |
| Point Transformer (ours)  |       0.93456      |     0.79787    |    0.83578     |
