# 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. If indices are not specified, joins across all dimensions beginning from n - 1 through 0.

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, []) ==> [["a", "b"], ["c", "d"]]
tf.reduce_join(a) = tf.reduce_join(a, [1, 0]) ==> "abcd"


Args:

• 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.
