concat_from_sequence#

ivy.concat_from_sequence(input_sequence, /, *, new_axis=0, axis=0, out=None)[source]#

Concatenate a sequence of arrays along a new or an existing axis.

Parameters:

  • input_sequence (Union[Tuple[Union[Array, NativeArray]], List[Union[Array, NativeArray]]]) – A sequence of arrays.

  • new_axis (int, default: 0) – Insert and concatenate on a new axis or not, default 0 means do not insert new axis. new_axis = 0: concatenate new_axis = 1: stack

  • axis (int, default: 0) – axis along which the arrays will be concatenated.

  • out (Optional[Array], default: None) – optional output array, for writing the result to.

Return type:

Array

Returns:

ret – Output Array

Array.concat_from_sequence(self, /, input_sequence, *, new_axis=0, axis=0, out=None)[source]#

Concatenate a sequence of arrays along a new or an existing axis.

Parameters:

  • self (Array) – Array input.

  • input_sequence (Union[Tuple[Union[Array, NativeArray]], List[Union[Array, NativeArray]]]) – A sequence of arrays.

  • new_axis (int, default: 0) – Insert and concatenate on a new axis or not, default 0 means do not insert new axis. new_axis = 0: concatenate new_axis = 1: stack

  • axis (int, default: 0) – The axis along which the arrays will be concatenated.

  • out (Optional[Array], default: None) – Optional output array, for writing the result to.

Return type:

Array

Returns:

ret – Output Array

Container.concat_from_sequence(self, /, input_sequence, *, new_axis=0, axis=0, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, out=None)[source]#

ivy.Container instance method variant of ivy.stack. This method simply wraps the function, and so the docstring for ivy.stack also applies to this method with minimal changes.

Parameters:

  • self (Container) –

    Container with leaves to join with leaves of other arrays/containers.

    Each array leave must have the same shape.

  • input_sequence (Union[Tuple[Union[Array, NativeArray, Container]], List[Union[Array, NativeArray, Container]]]) – Container with other leaves to join. Each array leave must have the same shape.

  • new_axis (Union[int, Container], default: 0) – Insert and concatenate on a new axis or not, default 0 means do not insert new axis. new_axis = 0: concatenate new_axis = 1: stack

  • axis (Union[int, Container], default: 0) – axis along which the array leaves will be concatenated. More details can be found in the docstring for ivy.stack.

  • key_chains (Optional[Union[List[str], Dict[str, str], Container]], default: None) – The key-chains to apply or not apply the method to. Default is None.

  • to_apply (Union[bool, Container], default: True) – If True, the method will be applied to key_chains, otherwise key_chains will be skipped. Default is True.

  • prune_unapplied (Union[bool, Container], default: False) – Whether to prune key_chains for which the function was not applied. Default is False.

  • map_sequences (Union[bool, Container], default: False) – Whether to also map method to sequences (lists, tuples). Default is False.

  • out (Optional[Container], default: None) – optional output array, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

Container

Returns:

ret – an output container with the results.

Examples

>>> x = ivy.Container(a=ivy.array([[0, 1], [2,3]]), b=ivy.array([[4, 5]]))
>>> y = ivy.Container(a=ivy.array([[3, 2], [1,0]]), b=ivy.array([[1, 0]]))
>>> z = ivy.Container.static_concat_from_sequence([x,y],axis=1)
>>> print(z)
{
    a: ivy.array([[[0, 1],
                [3, 2]],
                [[2, 3],
                [1, 0]]]),
    b: ivy.array([[[4, 5],
                [1, 0]]])
}
