Joins a string Tensor across the given dimensions.
tf.raw_ops.ReduceJoin(
inputs,
reduction_indices,
keep_dims=False,
separator='',
name=None
)
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 |
|---|
inputs
|
A Tensor of type string.
The input to be joined. All reduced indices must have non-zero size.
|
reduction_indices
|
A Tensor of type int32.
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.
|
keep_dims
|
An optional bool. Defaults to False.
If True, retain reduced dimensions with length 1.
|
separator
|
An optional string. Defaults to "".
The separator to use when joining.
|
name
|
A name for the operation (optional).
|
Returns |
|---|
A Tensor of type string.
