-
-    This operator changes the shape of ``x`` without changing its data.
-
-    The target shape can be given by ``shape`` or ``actual_shape``.
-    When ``shape`` and ``actual_shape`` are set at the same time,
-    ``actual_shape`` has a higher priority than ``shape``
-    but at this time ``shape`` can only be an integer list or tuple, and ``shape`` still should be set correctly to
-    guarantee shape inference in compile-time.
-
-    Some tricks exist when specifying the target shape.
-
-    1. -1 means the value of this dimension is inferred from the total element
-    number of x and remaining dimensions. Thus one and only one dimension can
-    be set -1.
-
-    2. 0 means the actual dimension value is going to be copied from the
-    corresponding dimension of x. The index of 0s in shape can not exceed
-    the dimension of x.
-
-    Here are some examples to explain it.
-
-    1. Given a 3-D tensor x with a shape [2, 4, 6], and the target shape
-    is [6, 8], the reshape operator will transform x into a 2-D tensor with
-    shape [6, 8] and leaving x's data unchanged.
-
-    2. Given a 3-D tensor x with a shape [2, 4, 6], and the target shape
-    specified is [2, 3, -1, 2], the reshape operator will transform x into a
-    4-D tensor with shape [2, 3, 4, 2] and leaving x's data unchanged. In this
-    case, one dimension of the target shape is set to -1, the value of this
-    dimension is inferred from the total element number of x and remaining
-    dimensions.
-
-    3. Given a 3-D tensor x with a shape [2, 4, 6], and the target shape
-    is [-1, 0, 3, 2], the reshape operator will transform x into a 4-D tensor
-    with shape [2, 4, 3, 2] and leaving x's data unchanged. In this case,
-    besides -1, 0 means the actual dimension value is going to be copied from
-    the corresponding dimension of x.
-
-    **Note**:
-        The parameter ``actual_shape`` will be deprecated in the future and only use ``shape`` instead to represent the target shape.
-
-    Args:
-        x(Tensor): An N-D Tensor. The data type is ``float32``, ``float64``, ``int32`` or ``int64``.
-        shape(list|tuple|Tensor): 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 Tensor, 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(Tensor)``. \
-                                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:
-        Tensor: A reshaped Tensor with the same data type 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.
