act (str): The non-linear activation to be applied to the reshaped tensor
variable.
inplace(bool): Must use :attr:`False` if :attr:`x` is used in multiple
operators. If this flag is set :attr:`True`, reuse input
:attr:`x` to reshape, which will change the shape of
tensor variable :attr:`x` and might cause errors when
:attr:`x` is used in multiple operators. If :attr:`False`,
preserve the shape :attr:`x` and create a new output tensor
variable whose data is copied from input x but reshaped.
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 layers' input, ``inplace`` must be :attr:`False`.
name (str): The name of this layer. It is optional.
