# tensorplay.functional.positive

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

```python
tensorplay.functional.positive(input) → Tensor
```

Returns input.
Throws a runtime error if input is a bool tensor.

Parameters:

input ([Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor)) – the input tensor.

Example:

```
>>> t = tensorplay.randn(5)
>>> t
tensor([ 0.0090, -0.2262, -0.0682, -0.2866,  0.3940])
>>> tensorplay.positive(t)
tensor([ 0.0090, -0.2262, -0.0682, -0.2866,  0.3940])
```
