# tensorflow::ops::ReduceJoin

`#include <string_ops.h>`

Joins a string Tensor across the given dimensions.

## Summary

Computes the string join across dimensions in the given string Tensor of shape `[d_0, d_1, ..., d_n-1]`. Returns a new Tensor created by joining the input strings with the given separator (default: empty string). Negative indices are counted backwards from the end, with `-1` being equivalent to `n - 1`.

For example:

``` `

# `tensor`a` is [["a", "b"], ["c", "d"]] tf.reduce_join(a, 0) ==> ["ac", "bd"] tf.reduce_join(a, 1) ==> ["ab", "cd"] tf.reduce_join(a, -2) = tf.reduce_join(a, 0) ==> ["ac", "bd"] tf.reduce_join(a, -1) = tf.reduce_join(a, 1) ==> ["ab", "cd"] tf.reduce_join(a, 0, keep_dims=True) ==> [["ac", "bd"]] tf.reduce_join(a, 1, keep_dims=True) ==> [["ab"], ["cd"]] tf.reduce_join(a, 0, separator=".") ==> ["a.c", "b.d"] tf.reduce_join(a, [0, 1]) ==> ["acbd"] tf.reduce_join(a, [1, 0]) ==> ["abcd"] tf.reduce_join(a, []) ==> ["abcd"] ```Arguments: scope: A Scope object inputs: The input to be joined. All reduced indices must have non-zero size. reduction_indices: The dimensions to reduce over. Dimensions are reduced in the order specified. Omitting `reduction_indices` is equivalent to passing `[n-1, n-2, ..., 0]`. Negative indices from `-n` to `-1` are supported. Optional attributes (see `Attrs`): keep_dims: If `True`, retain reduced dimensions with length `1`. separator: The separator to use when joining. Returns: `Output`: Has shape equal to that of the input with reduced dimensions removed or set to `1` depending on `keep_dims`.
