Computes the sum of elements across dimensions of a tensor. (deprecated arguments)
tf.compat.v1.reduce_sum(
input_tensor, axis=None, keepdims=None, name=None, reduction_indices=None,
keep_dims=None
)
Warning: SOME ARGUMENTS ARE DEPRECATED: (keep_dims). They will be removed in a future version.
Instructions for updating:
keep_dims is deprecated, use keepdims instead
Reduces input_tensor along the dimensions given in axis.
Unless keepdims is true, the rank of the tensor is reduced by 1 for each
entry in axis. 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.
x = tf.constant([[1, 1, 1], [1, 1, 1]])
tf.reduce_sum(x) # 6
tf.reduce_sum(x, 0) # [2, 2, 2]
tf.reduce_sum(x, 1) # [3, 3]
tf.reduce_sum(x, 1, keepdims=True) # [[3], [3]]
tf.reduce_sum(x, [0, 1]) # 6
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.The reduced tensor, of the same dtype as the input_tensor.
Equivalent to np.sum apart the fact that numpy upcast uint8 and int32 to int64 while tensorflow returns the same dtype as the input.
