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 length1
. - separator: The separator to use when joining.
Returns:
-
Output
: Has shape equal to that of the input with reduced dimensions removed or set to1
depending onkeep_dims
