tf.compat.v1.strings.split

Split elements of input based on sep.

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

Examples:

print(tf.compat.v1.strings.split(['hello world', 'a b c']))
SparseTensor(indices=tf.Tensor( [[0 0] [0 1] [1 0] [1 1] [1 2]], ...),
             values=tf.Tensor([b'hello' b'world' b'a' b'b' b'c'], ...),
             dense_shape=tf.Tensor([2 3], shape=(2,), dtype=int64))
print(tf.compat.v1.strings.split(['hello world', 'a b c'],
    result_type="RaggedTensor"))
<tf.RaggedTensor [[b'hello', b'world'], [b'a', b'b', b'c']]>

If sep is given, consecutive delimiters are not grouped together and are deemed to delimit empty strings. For example, input 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 start or end if the string has leading or trailing whitespace.

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