"""
This function return a Tensor with the `fill_value` which size is same as `shape`
This Op return a Tensor with the `fill_value` which size is same as `shape`
Args:
shape(list|tuple|Variable): Shape of the Tensor to be created.
The data type is ``int32`` or ``int64`` . If ``shape`` is a list or tuple,
the elements of it should be integers or Tensors with shape [1].
If ``shape`` is an Variable, it should be an 1-D Tensor .
value(float): The constant value used to initialize the Tensor to be created.
fill_value(bool|float16|float32|float64|int32|int64|Variable): The constant value
used to initialize the Tensor to be created. If fill_value is an Variable, it must be an 1-D Tensor.
out(Variable, optional): Optional output which can be any created
Variable that meets the requirements to store the result of operation.
if out is None, a new Varibale will be create to store the result.
dtype(np.dtype|core.VarDesc.VarType|str, optional): Data type of the output tensor
which can be float16, float32, float64, int32, int64, if dytpe is `None`, the data
type of created tensor is `float32`
device(str, optional): This parameter specifies that the Tensor is created
on the GPU or CPU.
device(str, optional): On which device to run this Op. The :attr:`device` must be
None, 'cpu' or 'gpu'. If :attr:`device` is None, the device that the user set in
the paddle program will be chosen. Default value is None.
stop_gradient(bool, optional): Indicating if we stop gradient from current(out) Variable,
default value is True.
name(str, optional): The default value is None. Normally there is no need for user to set this
property. For more information, please refer to :ref:`api_guide_Name`.
Returns:
Variable: Tensor which is created according to shape and dtype.
Raises:
TypeError: The `dtype` must be one of None, bool, float16, float32, float64, int32 and int64.
TypeError: The `out` must be a Variable.
TypeError: The `shape` must be one of Variable, list tuple.
