Computes the mean of t
ensor elements over
the given dimension.
Computes the mean of t
he input tensor's elements along
the given dimension.
Args:
input (Variable): The input variable which is a Tensor or LoDTensor.
dim (list|int|None): The dimension
s
along which the mean is computed. If
:attr:
`None`, compute the mean over all elements of :attr:`input`
and return a
Tensor variable with a single element, otherwise
dim (list|int|None): The dimension along which the mean is computed. If
`None`, compute the mean over all elements of :attr:`input`
and return a
variable with a single element, otherwise it
must be in the range :math:`[-rank(input), rank(input))`. If
:math:`dim[i] < 0`, the dimension to reduce is :math:`rank + dim[i]`.
:math:`dim[i] < 0`, the dimension to reduce is
:math:`rank(input) + dim[i]`.
keep_dim (bool): Whether to reserve the reduced dimension in the
output Tensor. The result tensor will have one fewer dimension
than the :attr:`input` unless :attr:`keep_dim` is true.
name(str|None): A name for this layer(optional). If set
None
, the layer
name(str|None): A name for this layer(optional). If set
`None`
, the layer
will be named automatically.
Returns:
Variable: The reduced
Tensor v
ariable.
Variable: The reduced
mean V
ariable.
