+## [参数不一致]torch.cuda.device
+
+### [torch.cuda.device](https://pytorch.org/docs/1.13/generated/torch.cuda.device.html#torch.cuda.device)
+
+```python
+torch.cuda.device(device)
+```
+
+### [paddle.CUDAPlace](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api/paddle/CUDAPlace_cn.html)
+
+```python
+paddle.CUDAPlace(id)
+```
+
+其中 Pytorch 与 Paddle 的参数支持类型不一致，具体如下：
+
+### 参数映射
+
+| PyTorch | PaddlePaddle | 备注                                                                             |
+| ------- | ------------ | -------------------------------------------------------------------------------- |
+| device  | id           | GPU 的设备 ID, Pytorch 支持 torch.device 和 int，Paddle 支持 int，需要进行转写。 |
+
+### 转写示例
+
+#### device: 获取 device 参数，对其取 device.index 值
+
+```python
+# Pytorch 写法
+torch.cuda.device(torch.device('cuda'))
+
+# Paddle 写法
+paddle.CUDAPlace(0)
+
+# 增加 index
+# Pytorch 写法
+torch.cuda.device(torch.device('cuda', index=index))
+
+# Paddle 写法
+paddle.CUDAPlace(index)
+```
