# ChainDataset

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

```python
class tensorplay.utils.data.ChainDataset(datasets: Iterable[Dataset])
```

Dataset for chaining multiple [IterableDataset](/docs/generated/tensorplay.utils.data.IterableDataset.html#tensorplay.utils.data.IterableDataset) s.

This class is useful to assemble different existing dataset streams. The
chaining operation is done on-the-fly, so concatenating large-scale
datasets with this class will be efficient.

Parameters:

datasets (iterable of [IterableDataset](/docs/generated/tensorplay.utils.data.IterableDataset.html#tensorplay.utils.data.IterableDataset)) – datasets to be chained together
