# tensorflow::ops::AccumulateNV2 Class Reference

# tensorflow::ops::AccumulateNV2

`#include <math_ops.h>`

Returns the element-wise sum of a list of tensors.

## Summary

`tf.accumulate_n_v2` performs the same operation as `tf.add_n`, but does not wait for all of its inputs to be ready before beginning to sum. This can save memory if inputs are ready at different times, since minimum temporary storage is proportional to the output size rather than the inputs size.

Unlike the original `accumulate_n`, `accumulate_n_v2` is differentiable.

Returns a `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` of same shape and type as the elements of `inputs`.

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- inputs: A list of `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/tensor#classtensorflow_1_1_tensor` objects, each with same shape and type.
- shape: Shape of elements of `inputs`.

Returns:

- `https://www.tensorflow.org/versions/r2.3/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The sum tensor.
