tf.string_split

Split elements of source based on delimiter. (deprecated arguments)

Aliases:

tf.compat.v1.string_split

tf.string_split(
    source,
    sep=None,
    skip_empty=True,
    delimiter=None,
    result_type='SparseTensor',
    name=None
)

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

If sep is an empty string, each element of the source is split into individual strings, each containing one byte. (This includes splitting multibyte sequences of UTF-8.) If delimiter contains multiple bytes, it is treated as a set of delimiters with each considered a potential split point.

Examples:

tf.strings.split(['hello world', 'a b c'])
tf.SparseTensor(indices=[[0, 0], [0, 1], [1, 0], [1, 1], [1, 2]],
                values=['hello', 'world', 'a', 'b', 'c']
                dense_shape=[2, 3])

```
tf.strings.split(['hello world', 'a b c'], result_type="RaggedTensor")
<tf.RaggedTensor [['hello', 'world'], ['a', 'b', 'c']]>


#### Args:


* <b>`source`</b>: `1-D` string `Tensor`, the strings to split.
* <b>`sep`</b>: `0-D` string `Tensor`, the delimiter character, the string should
  be length 0 or 1. Default is ' '.
* <b>`skip_empty`</b>: A `bool`. If `True`, skip the empty strings from the result.
* <b>`delimiter`</b>: deprecated alias for `sep`.
* <b>`result_type`</b>: The tensor type for the result: one of `"RaggedTensor"` or
  `"SparseTensor"`.
* <b>`name`</b>: A name for the operation (optional).


#### Raises:


* <b>`ValueError`</b>: If delimiter is not a string.


#### Returns:

A `SparseTensor` or `RaggedTensor` of rank `2`, the strings split according
to the delimiter.  The first column of the indices corresponds to the row
in `source` and the second column corresponds to the index of the split
component in this row.
