Split - version 11
==================

This page documents version **11** of operator **Split**. See :doc:`Split` for the latest version (since version 18).

- **Domain**: ``ai.onnx``
- **Since version**: 11

Split a tensor into a list of tensors, along the specified
'axis'. Lengths of the parts can be specified using argument 'split'.
Otherwise, the tensor is split to equal sized parts.

**Inputs**

- **input** (*T*): The tensor to split

**Outputs**

Between 1 and ∞ outputs.

- **outputs** (*T*): One or more outputs forming list of tensors after splitting

**Attributes**

- **axis** (*int*): Which axis to split on. A negative value means counting dimensions from the back. Accepted range is [-rank, rank-1] where r = rank(input).
- **split** (*int[]*): length of each output. Values should be >= 0.

**Type Constraints**

- **T**: Constrain input and output types to all tensor types.
  Allowed types: tensor(bool), tensor(complex128), tensor(complex64), tensor(double), tensor(float), tensor(float16), tensor(int16), tensor(int32), tensor(int64), tensor(int8), tensor(string), tensor(uint16), tensor(uint32), tensor(uint64), tensor(uint8).
