# tensorplay.functional.ravel

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

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

Return a contiguous flattened tensor. A copy is made only if needed.

Parameters:

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

Example:

```
>>> t = tensorplay.tensor([[[1, 2],
...                    [3, 4]],
...                   [[5, 6],
...                    [7, 8]]])
>>> tensorplay.ravel(t)
tensor([1, 2, 3, 4, 5, 6, 7, 8])
```
