# tensorflow::ops::Mean

`#include <math_ops.h>`

Computes the mean of elements across dimensions of a tensor.

## Summary

Reduces `input` along the dimensions given in `axis`. Unless `keep_dims` is true, the rank of the tensor is reduced by 1 for each entry in `axis`. If `keep_dims` is true, the reduced dimensions are retained with length 1.

Arguments:

- scope: A [Scope](https://www.tensorflow.org/versions/r2.0/api_docs/cc/class/tensorflow/scope#classtensorflow_1_1_scope) object
- input: The tensor to reduce.
- axis: The dimensions to reduce. Must be in the range `[-rank(input), rank(input))`.

<br />

Optional attributes (see `https://www.tensorflow.org/versions/r2.0/api_docs/cc/struct/tensorflow/ops/mean/attrs#structtensorflow_1_1ops_1_1_mean_1_1_attrs`):

- keep_dims: If true, retain reduced dimensions with length 1.

<br />

Returns:

- `https://www.tensorflow.org/versions/r2.0/api_docs/cc/class/tensorflow/output#classtensorflow_1_1_output`: The reduced tensor.

<br />

Aliases:

- ReduceMean
