Squeeze - version 24
====================

This page documents version **24** of operator **Squeeze**. See :doc:`Squeeze` for the latest version (since version 25).

- **Domain**: ``ai.onnx``
- **Since version**: 24

Remove single-dimensional entries from the shape of a tensor.
Takes an input ``axes`` with a list of axes to squeeze.
If ``axes`` is not provided, all the single dimensions will be removed from
the shape. If an axis is selected with shape entry not equal to one, an error is raised.

**Inputs**

- **data** (*T*): Tensors with at least max(dims) dimensions.
- **axes** (*tensor(int64)*): 1D tensor of integers indicating the dimensions to squeeze. Negative value means counting dimensions from the back. Accepted range is [-r, r-1] where r = rank(data).

**Outputs**

- **squeezed** (*T*): Reshaped tensor with same data as input.

**Type Constraints**

- **T**: Constrain input and output types to all tensor types up to IRv12.
  Allowed types: tensor(bfloat16), tensor(bool), tensor(complex128), tensor(complex64), tensor(double), tensor(float), tensor(float16), tensor(float4e2m1), tensor(float8e4m3fn), tensor(float8e4m3fnuz), tensor(float8e5m2), tensor(float8e5m2fnuz), tensor(float8e8m0), tensor(int16), tensor(int32), tensor(int4), tensor(int64), tensor(int8), tensor(string), tensor(uint16), tensor(uint32), tensor(uint4), tensor(uint64), tensor(uint8).
