Let N be the size of source (typically N will be the batch size). Split each
element of input based on delimiter and return a SparseTensor
containing the splitted tokens. Empty tokens are ignored.
delimiter can be empty, or a string of split characters. If delimiter is an
empty string, each element of input is split into individual single-byte
character strings, including splitting of UTF-8 multibyte sequences. Otherwise
every character of delimiter is a potential split point.
For example
N = 2, input[0] is 'hello world' and input[1] is 'a b c', then the output
will be
