tf.strings.reduce_join

Joins all strings into a single string, or joins along an axis.

tf.strings.reduce_join(
    inputs, axis=None, keepdims=False, separator='', name=None
)

>>> tf.strings.reduce_join([['abc','123'],
...                         ['def','456']]).numpy()
b'abc123def456'
>>> tf.strings.reduce_join([['abc','123'],
...                         ['def','456']], axis=-1).numpy()
array([b'abc123', b'def456'], dtype=object)
>>> tf.strings.reduce_join([['abc','123'],
...                         ['def','456']],
...                        axis=-1,
...                        separator=" ").numpy()
array([b'abc 123', b'def 456'], dtype=object)

Args

inputs A tf.string tensor.
axis Which axis to join along. The default behavior is to join all elements, producing a scalar.
keepdims If true, retains reduced dimensions with length 1.
separator a string added between each string being joined.
name A name for the operation (optional).

Returns

A tf.string tensor.
