tf.compat.v1.reduce_sum
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
)
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.
For example:
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
| 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, of the same dtype as the input_tensor. |
Numpy Compatibility
Equivalent to np.sum apart the fact that numpy upcast uint8 and int32 to int64 while tensorflow returns the same dtype as the input.
