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 istf.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).
Returns
A tf.string tensor.
