squeeze#
- ivy.squeeze(x, /, axis, *, copy=None, out=None)[source]#
Remove singleton dimensions (axes) from x.
- Parameters:
x (
Union
[Array
,NativeArray
]) – input array.axis (
Union
[int
,Sequence
[int
]]) – axis (or axes) to squeeze. If a specified axis has a size greater than one, a ValueError is. If None, then all squeezable axes are squeezed. Default:None
out (
Optional
[Array
]) – optional output array, for writing the result to. It must have a shape that the (default:None
) inputs broadcast to.
- Return type:
- Returns:
ret – an output array having the same data type and elements as x.
This function conforms to the Array API Standard. This docstring is an extension of the docstring # noqa in the standard.
Both the description and the type hints above assumes an array input for simplicity, but this function is nestable, and therefore also accepts
ivy.Container
instances in place of any of the arguments.Functional Examples
With
ivy.Array
input:>>> x = ivy.array([[[0, 1], [2, 3]]]) >>> print(ivy.squeeze(x, axis=0)) ivy.array([[0, 1], [2, 3]])
>>> x = ivy.array([[[[1, 2, 3]], [[4, 5, 6]]]]) >>> print(ivy.squeeze(x, axis=2)) ivy.array([[[1, 2, 3], [4, 5, 6]]])
>>> x = ivy.array([[[0], [1], [2]]]) >>> print(ivy.squeeze(x, axis=None)) ivy.array([0, 1, 2])
>>> print(ivy.squeeze(x, axis=0)) ivy.array([[0], [1], [2]])
>>> print(ivy.squeeze(x, axis=2)) ivy.array([[0, 1, 2]])
>>> print(ivy.squeeze(x, axis=(0, 2))) ivy.array([0, 1, 2])
With
ivy.Container
input:>>> x = ivy.Container(a=ivy.array([0., 1., 2.]), ... b=ivy.array([3., 4., 5.])) >>> y = ivy.squeeze(x, axis=None) >>> print(y) { a: ivy.array([0., 1., 2.]), b: ivy.array([3., 4., 5.]) }
- Array.squeeze(self, /, axis, *, copy=None, out=None)#
ivy.Array instance method variant of ivy.squeeze. This method simply wraps the function, and so the docstring for ivy.squeeze also applies to this method with minimal changes.
Examples
>>> x = ivy.array([[[0.],[ 1.]]]) >>> y = x.squeeze(2) >>> print(y) ivy.array([[0., 1.]])
- Return type:
Array
- Container.squeeze(self, /, axis, *, copy=None, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, out=None)#
ivy.Container instance method variant of ivy.squeeze. This method simply wraps the function, and so the docstring for ivy.squeeze also applies to this method with minimal changes.
- Parameters:
self (
Container
) – input container.axis (
Union
[int
,Sequence
[int
]]) – axis (or axes) to squeeze.key_chains (
Optional
[Union
[List
[str
],Dict
[str
,str
]]]) – The key-chains to apply or not apply the method to. Default isNone
. (default:None
)to_apply (
bool
) – If True, the method will be applied to key_chains, otherwise key_chains (default:True
) will be skipped. Default isTrue
.prune_unapplied (
bool
) – Whether to prune key_chains for which the function was not applied. (default:False
) Default isFalse
.map_sequences (
bool
) – Whether to also map method to sequences (lists, tuples). (default:False
) Default isFalse
.out (
Optional
[Container
]) – optional output container, for writing the result to. It must have a shape (default:None
) that the inputs broadcast to.
- Return type:
Container
- Returns:
ret – an output container with the results.
Examples
>>> x = ivy.Container(a=ivy.array([[[10.], [11.]]]), ... b=ivy.array([[[11.], [12.]]])) >>> y = x.squeeze(2) >>> print(y) { a: ivy.array([[10., 11.]]), b: ivy.array([[11., 12.]]) }
>>> x = ivy.Container(a=ivy.array([[[10.], [11.]]]), ... b=ivy.array([[[11.], [12.]]])) >>> y = x.squeeze(0) >>> print(y) { a: ivy.array([[10.], [11.]]), b: ivy.array([[11.], [12.]]) }
