This is the reduction operation for the elementwise tf.strings.join op.

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.
