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 .
