Class StringSplitV2

java.lang.Object

org.tensorflow.op.PrimitiveOp

org.tensorflow.op.core.StringSplitV2

All Implemented Interfaces:

Op

@Operator
public final class StringSplitV2
extends PrimitiveOp

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.

Method Detail

create

public static StringSplitV2 create(Scope scope,
                                   Operand<String> input,
                                   Operand<String> sep,
                                   StringSplitV2.Options... options)

Factory method to create a class to wrap a new StringSplitV2 operation to the graph.

Parameters:

scope - current graph scope

input - `1-D` string `Tensor`, the strings to split.

sep - `0-D` string `Tensor`, the delimiter character.

options - carries optional attributes values

Returns:

a new instance of StringSplitV2

maxsplit

public static StringSplitV2.Options maxsplit(Long maxsplit)

Parameters:

maxsplit - An `int`. If `maxsplit > 0`, limit of the split of the result.

indices

public Output<Long> indices()

values

public Output<String> values()

shape

public Output<Long> shape()
