:class: output
Help on function ones in module mxnet.numpy:
ones(shape, dtype=, order='C', ctx=None)
Return a new array of given shape and type, filled with ones.
This function currently only supports storing multi-dimensional data
in row-major (C-style).
Parameters
----------
shape : int or tuple of int
The shape of the empty array.
dtype : str or numpy.dtype, optional
An optional value type. Default is `numpy.float32`. Note that this
behavior is different from NumPy's `ones` function where `float64`
is the default value, because `float32` is considered as the default
data type in deep learning.
order : {'C'}, optional, default: 'C'
How to store multi-dimensional data in memory, currently only row-major
(C-style) is supported.
ctx : Context, optional
An optional device context (default is the current default context).
Returns
-------
out : ndarray
Array of ones with the given shape, dtype, and ctx.
Examples
--------
>>> np.ones(5)
array([1., 1., 1., 1., 1.])
>>> np.ones((5,), dtype=int)
array([1, 1, 1, 1, 1], dtype=int64)
>>> np.ones((2, 1))
array([[1.],
[1.]])
>>> s = (2,2)
>>> np.ones(s)
array([[1., 1.],
[1., 1.]])

ones(*size, *, out=None, dtype=None, layout=torch.strided, device=None, requires_grad=False) -> Tensor
Returns a tensor filled with the scalar value `1`, with the shape defined
by the variable argument :attr:`size`.
Args:
size (int...): a sequence of integers defining the shape of the output tensor.
Can be a variable number of arguments or a collection like a list or tuple.
Keyword arguments:
out (Tensor, optional): the output tensor.
dtype (:class:`torch.dtype`, optional): the desired data type of returned tensor.
Default: if ``None``, uses a global default (see :func:`torch.set_default_tensor_type`).
layout (:class:`torch.layout`, optional): the desired layout of returned Tensor.
Default: ``torch.strided``.
device (:class:`torch.device`, optional): the desired device of returned tensor.
Default: if ``None``, uses the current device for the default tensor type
(see :func:`torch.set_default_tensor_type`). :attr:`device` will be the CPU
for CPU tensor types and the current CUDA device for CUDA tensor types.
requires_grad (bool, optional): If autograd should record operations on the
returned tensor. Default: ``False``.
Example::
>>> torch.ones(2, 3)
tensor([[ 1., 1., 1.],
[ 1., 1., 1.]])
>>> torch.ones(5)
tensor([ 1., 1., 1., 1., 1.])

help(tf.ones)
.. parsed-literal::
:class: output
Help on function ones in module tensorflow.python.ops.array_ops:
ones(shape, dtype=tf.float32, name=None)
Creates a tensor with all elements set to one (1).
See also `tf.ones_like`, `tf.zeros`, `tf.fill`, `tf.eye`.
This operation returns a tensor of type `dtype` with shape `shape` and
all elements set to one.
>>> tf.ones([3, 4], tf.int32)
Args:
shape: A `list` of integers, a `tuple` of integers, or
a 1-D `Tensor` of type `int32`.
dtype: Optional DType of an element in the resulting `Tensor`. Default is
`tf.float32`.
name: Optional string. A name for the operation.
Returns:
A `Tensor` with all elements set to one (1).
