tf.compat.v1.math.reduce_prod
tf . compat . v1 . reduce_prod (
input_tensor ,
axis = None ,
keepdims = None ,
name = None ,
reduction_indices = None ,
keep_dims = None
)
Deprecated: SOME ARGUMENTS ARE DEPRECATED: (keep_dims)
. They will be removed in a future version.
Instructions for updating:
keep_dims is deprecated, use keepdims instead
This is the reduction operation for the elementwise tf.math.multiply
op.
Reduces input_tensor
along the dimensions given in axis
.
Unless keepdims
is true, the rank of the tensor is reduced by 1 for each
of the entries in axis
, which must be unique. If keepdims
is true, the
reduced dimensions are retained with length 1.
If axis
is None, all dimensions are reduced, and a
tensor with a single element is returned.
For example
>>> x = tf . constant ([[ 1. , 2. ], [ 3. , 4. ]])
>>> tf . math . reduce_prod ( x )
<tf . Tensor : shape = (), dtype = float32 , numpy = 24. >
>>> tf . math . reduce_prod ( x , 0 )
<tf . Tensor : shape = ( 2 ,), dtype = float32 , numpy = array ([ 3. , 8. ], dtype = float32 ) >
>>> tf . math . reduce_prod ( x , 1 )
<tf . Tensor : shape = ( 2 ,), dtype = float32 , numpy = array ([ 2. , 12. ],
dtype = float32 ) >
Args
input_tensor
The tensor to reduce. Should have numeric type.
axis
The dimensions to reduce. If None
(the default), reduces all
dimensions. Must be in the range [-rank(input_tensor),
rank(input_tensor))
.
keepdims
If true, retains reduced dimensions with length 1.
name
A name for the operation (optional).
reduction_indices
The old (deprecated) name for axis.
keep_dims
Deprecated alias for keepdims
.
Returns
The reduced tensor.
