)
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)
