StringSplit

public final class StringSplit

Split elements of `source` based on `sep` into a `SparseTensor`.

Let N be the size of source (typically N will be the batch size). Split each element of `source` based on `sep` and return a `SparseTensor` containing the split tokens. Empty tokens are ignored.

For example, N = 2, source[0] is 'hello world' and source[1] is 'a b c', then the output will be

st.indices = [0, 0;
               0, 1;
               1, 0;
               1, 1;
               1, 2]
 st.shape = [2, 3]
 st.values = ['hello', 'world', 'a', 'b', 'c']
 
If `sep` is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings. For example, source of `"1<>2<><>3"` and sep of `"<>"` returns `["1", "2", "", "3"]`. If `sep` is None or an empty string, consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the startor end if the string has leading or trailing whitespace.

Note that the above mentioned behavior matches python's str.split.
