Source: https://www.tensorplay.cn/docs/generated/tensorplay.functional.atanh.html

```python
tensorplay.functional.atanh(input: Tensor, *, out: Tensor | None) → Tensor
```

Returns a new tensor with the inverse hyperbolic tangent of the elements of input.

> **Note**
>
> The domain of the inverse hyperbolic tangent is (-1, 1) and values outside this range will be mapped to NaN, except for the values 1 and -1 for which the output is mapped to +/-INF respectively. @@TPBLOCK_1@@ Parameters : input (Tensor) – the input tensor. Keyword Arguments : out (Tensor, optional) – the output tensor. Example: @@TPBLOCK_0@@
