UnicodeEncode

public final class UnicodeEncode

Encode a tensor of ints into unicode strings.

Returns a vector of strings, where `output[i]` is constructed by encoding the Unicode codepoints in `input_values[input_splits[i]:input_splits[i+1]]` using `output_encoding`.

---

Example:

input_values = [72, 101, 108, 108, 111, 87, 111, 114, 108, 100]
 input_splits = [0, 5, 10]
 output_encoding = 'UTF-8'
 
 output = ['Hello', 'World']

Constants

public static final String OP_NAME

The name of this op, as known by TensorFlow core engine

Constant Value: "UnicodeEncode"

Public Methods

public Output<TString> asOutput ()

Returns the symbolic handle of the tensor.

Inputs to TensorFlow operations are outputs of another TensorFlow operation. This method is used to obtain a symbolic handle that represents the computation of the input.

public static UnicodeEncode create (Scope scope, Operand<TInt32> inputValues, Operand<? extends TNumber> inputSplits, String outputEncoding, Options... options)

Factory method to create a class wrapping a new UnicodeEncode operation.

Parameters

scope	current scope
inputValues	A 1D tensor containing the unicode codepoints that should be encoded.
inputSplits	A 1D tensor specifying how the unicode codepoints should be split into strings. In particular, `output[i]` is constructed by encoding the codepoints in the slice `input_values[input_splits[i]:input_splits[i+1]]`.
outputEncoding	Unicode encoding of the output strings. Valid encodings are: `"UTF-8", "UTF-16-BE", and "UTF-32-BE"`.
options	carries optional attributes values

Returns

a new instance of UnicodeEncode

public static UnicodeEncode.Options errors (String errors)

Parameters

errors	Error handling policy when there is invalid formatting found in the input. The value of 'strict' will cause the operation to produce a InvalidArgument error on any invalid input formatting. A value of 'replace' (the default) will cause the operation to replace any invalid formatting in the input with the `replacement_char` codepoint. A value of 'ignore' will cause the operation to skip any invalid formatting in the input and produce no corresponding output character.

public Output<TString> output ()

The 1-D Tensor of strings encoded from the provided unicode codepoints.

public static UnicodeEncode.Options replacementChar (Long replacementChar)

Parameters

replacementChar	The replacement character codepoint to be used in place of any invalid formatting in the input when `errors='replace'`. Any valid unicode codepoint may be used. The default value is the default unicode replacement character is 0xFFFD (U+65533).
