Given a list of string tensors of same shape, performs element-wise
concatenation of the strings of the same index in all tensors.
tf.strings.join(['abc','def']).numpy()
b'abcdef'
tf.strings.join([['abc','123'],
['def','456'],
['ghi','789']]).numpy()
array([b'abcdefghi', b'123456789'], dtype=object)
tf.strings.join([['abc','123'],
['def','456']],
separator=" ").numpy()
array([b'abc def', b'123 456'], dtype=object)
The reduction version of this elementwise operation is
tf.strings.reduce_join
Args |

inputs
|
A list of tf.Tensor objects of same size and tf.string dtype.
|
separator
|
A string added between each string being joined.
|
name
|
A name for the operation (optional).
