Determine wordshape features for each input string.

Used in the tutorials

In this example, we test for title case (the first character is upper or title case, and the remaining characters are lowercase).

  >>> input = [
  ... u"abc", u"ABc", u"ABC", u"Abc", u"aBcd", u"\u01c8bc".encode("utf-8")
  ... ]
  >>> wordshape(input, WordShape.HAS_TITLE_CASE)
  <tf.Tensor: shape=(6,), dtype=bool,
   numpy=array([False, False, False,  True, False,  True])>

input_tensor string Tensor with any shape.
pattern A tftext.WordShape or a list of WordShapes.
name A name for the operation (optional).

<bool>[input_tensor.shape + pattern.shape]: A tensor where result[i1...iN, j] is true if input_tensor[i1...iN] has the wordshape specified by pattern[j].

ValueError If pattern contains an unknown identifier.
