besides -1, 0 means the actual dimension value is going to be copied from
the corresponding dimension of x.
**Warning:** the parameter :attr:`actual_shape` will be deprecated in the future and only use :attr:`shape` instead.
**Note**:
The parameter ``actual_shape`` will be deprecated in the future and only use ``shape`` instead to represent the target shape.
Args:
x(variable): The input tensor.
shape(list|tuple|Variable): The new shape. At most one dimension of the new shape can
be -1. If :attr:`shape` is a list or tuple, it can contain Variable or not and
the shape of Variable must be [1].
actual_shape(variable): An optional input. If provided, reshape
according to this given shape rather than
:attr:`shape` specifying shape. That is to
say :attr:`actual_shape` has a higher priority
than :attr:`shape(list|tuple)` but not :attr:`shape(Variable)`. \
This argument :attr:`actual_shape` will be removed in a future version. \
Instructions for updating: :attr:`actual_shape` is deprecated,
only use :attr:`shape` instead.
act (str): The non-linear activation to be applied to the reshaped tensor
variable.
inplace(bool): If ``inplace`` is `True`, the input and output of ``layers.reshape``
are the same variable, otherwise, the input and output of
``layers.reshape`` are different variables. Note that if :attr:`x`
is more than one layer's input, ``inplace`` must be :attr:`False`.
name (str): The name of this layer. It is optional.
x(Variable): A ``Tensor`` or ``LoDTensor`` . The data type is ``float32``, ``float64``, ``int32`` or ``int64``.
shape(list|tuple|Variable): Define the target shape. At most one dimension of the target shape can be -1.
The data type is ``int32`` . 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 .
actual_shape(variable, optional): An 1-D ``Tensor`` or ``LoDTensor`` . The data type is ``int32`` . If provided, reshape
according to this given shape rather than ``shape`` specifying shape.
That is to say ``actual_shape`` has a higher priority
than ``shape(list|tuple)`` but not ``shape(Variable)``. \
This argument ``actual_shape`` will be removed in a future version. \
Instructions for updating: ``actual_shape`` will be removed in future versions and replaced by ``shape``.
act (str, optional): The non-linear activation to be applied to the reshaped input. Default None.
inplace(bool, optional): If ``inplace`` is True, the input and output of ``layers.reshape``
are the same variable. Otherwise, the input and output of
``layers.reshape`` are different variable. Default False. Note that if ``x``
is more than one OPs' input, ``inplace`` must be False.
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: The reshaped tensor variable if :attr:`act` is None. It is a \
new tensor variable if :attr:`inplace` is :attr:`False`, \
otherwise it is :attr:`x`. If :attr:`act` is not None, return \
the activated tensor variable.
Variable: A ``Tensor`` or ``LoDTensor``. The data type is same as ``x``. It is a new tensor variable if ``inplace`` is ``False``, otherwise it is ``x``. If ``act`` is None, return the reshaped tensor variable, otherwise return the activated tensor variable.
Raises:
TypeError: if actual_shape is neither Variable nor None.
TypeError: If actual_shape is neither Variable nor None.
ValueError: If more than one elements of ``shape`` is -1.
ValueError: If the element of ``shape`` is 0, the corresponding dimension should be less than or equal to the dimension of ``x``.
ValueError: If the elements in ``shape`` is negative except -1.
factor(float|Variable|1.0): The exponential factor of Pow.
name(str|None): A name for this layer(optional). If set None, the layer
will be named automatically.
x(Variable): A ``Tensor`` or ``LoDTensor`` . The data type is ``float32`` or ``float64``.
factor(float32|Variable, optional): A scalar with type ``float32`` or a ``Tensor`` with shape [1] and type ``float32``. The exponential factor of Pow. Default 1.0.
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:
output(${out_type}): ${out_comment}
Variable: A ``Tensor`` or ``LoDTensor``. The data type is same as ``x``.
expand_times (list|tuple|Variable): Expand times number for each dimension.
x (Variable): A ``Tensor`` or ``LoDTensor`` with dimension in [1, 6]. The data type is ``bool``, ``float32``, ``float64`` or ``int32`` .
expand_times (list|tuple|Variable): The data type is ``int32`` . If ``expand_times`` is a list or tuple, the elements of
it should be integers or Tensors with shape [1]. If ``expand_times`` is an Variable, it should be an 1-D Tensor.
Expand times number for each dimension of ``x`` .
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: The expanded variable which is a LoDTensor. After expanding, size of each dimension of Output(Out) is equal to ithe size of the corresponding dimension of Input(X) multiplying the corresponding value given by expand_times.
Variable: A ``Tensor`` or ``LoDTensor``. The data type is same as ``x``. After expanding, size of each dimension of output is equal to the size of the corresponding dimension of ``x`` multiplying the corresponding value given by ``expand_times`` .
Raises:
TypeError: The type of ``expand_times`` must be list, tuple or Variable.
ValueError: The elements of ``expand_times`` cannot be negative.
