tf.compat.v1.reduce_join

View source on GitHub

Joins all strings into a single string, or joins along an axis.

tf.compat.v1.reduce_join(
    inputs,
    axis=None,
    keep_dims=None,
    separator='',
    name=None,
    reduction_indices=None,
    keepdims=None
)
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.
