# 自定义OP编译
|
||
|
|
旋转框IOU计算OP是参考[自定义外部算子](https://www.paddlepaddle.org.cn/documentation/docs/zh/guides/custom_op/new_cpp_op_cn.html) 。
|
||
|
|
|
||
|
|
## 1. 环境依赖
|
||
|
|
- Paddle >= 2.0.1
|
||
|
|
- gcc 8.2
|
||
|
|
|
||
|
|
## 2. 安装
|
||
|
|
```
|
||
|
|
python setup.py install
|
||
|
|
```
|
||
|
|
|
||
|
|
编译完成后即可使用，以下为`rbox_iou`的使用示例
|
||
|
|
```
|
||
|
|
# 引入自定义op
|
||
|
|
from ext_op import rbox_iou
|
||
|
|
|
||
|
|
paddle.set_device('gpu:0')
|
||
|
|
paddle.disable_static()
|
||
|
|
|
||
|
|
rbox1 = np.random.rand(13000, 5)
|
||
|
|
rbox2 = np.random.rand(7, 5)
|
||
|
|
|
||
|
|
pd_rbox1 = paddle.to_tensor(rbox1)
|
||
|
|
pd_rbox2 = paddle.to_tensor(rbox2)
|
||
|
|
|
||
|
|
iou = rbox_iou(pd_rbox1, pd_rbox2)
|
||
|
|
print('iou', iou)
|
||
|
|
```
|
||
|
|
|
||
|
|
## 3. 单元测试
|
||
|
|
可以通过执行单元测试来确认自定义算子功能的正确性，执行单元测试的示例如下所示：
|
||
|
|
```
|
||
|
|
python unittest/test_matched_rbox_iou.py
|
||
|
|
```
