+## [参数完全一致]torch.Tensor.nan_to_num
+
+### [torch.Tensor.nan_to_num](https://pytorch.org/docs/1.13/generated/torch.Tensor.nan_to_num.html#torch.Tensor.nan_to_num)
+
+```python
+torch.Tensor.nan_to_num(nan=0.0, posinf=None, neginf=None)
+```
+
+### [paddle.Tensor.nan_to_num](https://www.paddlepaddle.org.cn/documentation/docs/zh/develop/api/paddle/Tensor_cn.html#nan-to-num)
