# tensorplay.utils.data.default_collate

Source: https://www.tensorplay.cn/docs/generated/tensorplay.utils.data.default_collate.html

```python
tensorplay.utils.data.default_collate(batch)
```

Take in a batch of data and put the elements within the batch into a
tensor with an additional outer dimension - batch size.

The exact output type can be a [tensorplay.Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), a Sequence of
[tensorplay.Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), a Collection of [tensorplay.Tensor](/docs/generated/tensorplay.Tensor.html#tensorplay.Tensor), or
left unchanged, depending on the input type. This is used as the default
function for collation when batch_size or batch_sampler is defined in
[DataLoader](/docs/generated/tensorplay.utils.data.DataLoader.html#tensorplay.utils.data.DataLoader).

Parameters:

batch – a single batch to be collated
