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

  • copy (Optional[Union[bool, Container]], default: None) – boolean indicating whether or not to copy the input array. If True, the function must always copy. If False, the function must never copy and must raise a ValueError in case a copy would be necessary. If None, the function must reuse existing memory buffer if possible and copy otherwise. Default: 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 container, for writing the result to. It must have a shape that the inputs broadcast to.

Return type:

Container

Returns:

ret – container with tensors of zeros with the same shape and type as the inputs, unless dtype provided which overrides.

>>> y = 5
>>> z = x.one_hot(y)
>>> print(z)
{
    a: ivy.array([[0., 1., 0., 0., 0.],
                [0., 0., 1., 0., 0.]]),
    b: ivy.array([[0., 0., 0., 1., 0.],

ones_like(key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False, *, dtype=None, device=None, out=None)[source]#

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

Parameters:
  • self (Container) – input array from which to derive the output array shape.

  • 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.

  • dtype (Optional[Union[Dtype, NativeDtype, Container]], default: None) – output array data type. If dtype is None, the output array data type must be inferred from self. Default None.

  • device (Optional[Union[Device, NativeDevice, Container]], default: None) – device on which to place the created array. If device is None, the output array device must be inferred from self. Default: None.

  • 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 – a container having the same shape as self and filled with ones.

static static_frombuffer(buffer, dtype=<class 'float'>, count=-1, offset=0, key_chains=None, to_apply=True, prune_unapplied=False, map_sequences=False)[source]#

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

Parameters:
  • buffer (Container) – An object that exposes the buffer interface.

  • dtype (Optional[Union[Dtype, NativeDtype, Container]], default: <class 'float'>) – Data-type of the returned array; default: float.

  • count (Optional[Union[int, Container]], default: -1) – Number of items to read. -1 means all data in the buffer.

  • offset (Optional[Union[int, Container]], default: 0) – Start reading the buffer from this offset (in bytes); default: 0.

  • 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.
