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) 

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.
