Operatori TensorFlow Text e SentencePiece

I seguenti operatori TensorFlow Text e SentencePiece sono supportati se utilizzi l'API Python per la conversione e importi queste librerie.

Operatori TF.Text:

CaseFoldUTF8
ConstrainedSequence
MaxSpanningTree
NormalizeUTF8
NormalizeUTF8WithOffsetsMap
RegexSplitWithOffsets
RougeL
SentenceFragments
SentencepieceOp
SentencepieceTokenizeOp
SentencepieceTokenizeWithOffsetsOp
SentencepieceDetokenizeOp
SentencepieceVocabSizeOp
SplitMergeTokenizeWithOffsets
UnicodeScriptTokenizeWithOffsets
WhitespaceTokenizeWithOffsets
WordpieceTokenizeWithOffsets

Operatori di SentencePiece:

SentencepieceGetPieceSize
SentencepiecePieceToId
SentencepieceIdToPiece
SentencepieceEncodeDense
SentencepieceEncodeSparse
SentencepieceDecode

Il seguente snippet mostra come convertire i modelli con gli operatori sopra indicati:

import tensorflow as tf
# These imports are required to load operators' definition.
import tensorflow_text as tf_text
import sentencepiece as spm

converter = tf.lite.TFLiteConverter.from_keras_model(your_model)
converter.target_spec.supported_ops = [
  tf.lite.OpsSet.TFLITE_BUILTINS, tf.lite.OpsSet.SELECT_TF_OPS
]
model_data = converter.convert()

Sul lato runtime, è inoltre necessario collegare la libreria TensorFlow Text o SentencePiece all'app o al programma binario finale.

Operatori definiti dall'utente

Nota: questa funzionalità è disponibile solo a partire dalla versione TensorFlow 2.5

Se hai creato i tuoi operatori TensorFlow, puoi anche convertire in TensorFlow Lite i modelli che li contengono elencando gli operatori richiesti nella experimental_select_user_tf_ops, come indicato di seguito:

import tensorflow as tf

ops_module = tf.load_op_library('./your_ops_library.so')

converter = tf.lite.TFLiteConverter.from_saved_model(your_model)
converter.target_spec.supported_ops = [
  tf.lite.OpsSet.TFLITE_BUILTINS, tf.lite.OpsSet.SELECT_TF_OPS
]
converter.target_spec.experimental_select_user_tf_ops = [
    'your_op_name1',
    'your_op_name2'
]
model_data = converter.convert()

Sul lato runtime, è inoltre necessario collegare la libreria degli operatori all'app finale o al programma binario.

Aggiungi gli operatori TensorFlow core all'elenco degli operatori consentiti.

Se riscontri un caso in cui gli operatori TensorFlow core non sono inclusi nell'elenco consentito sopra, puoi segnalare la richiesta di funzionalità qui con i nomi degli operatori principali di TensorFlow, non elencati nell'elenco consentito.

Puoi anche creare una richiesta di pull personalizzata dal codice sorgente. Ad esempio, se vuoi aggiungere l'operazione raw_ops.StringToNumber nell'elenco degli elementi consentiti, ci sono tre posizioni da aggiornare come questo commit.

(1) Aggiungi il codice sorgente del kernel dell'operatore alla regola portable_extended_ops_group2 Build.

filegroup(
    name = "portable_extended_ops_group2",
    srcs = [
        ...
+   "string_to_number_op.cc",

        ...
    ],
)

Per trovare il file di origine del kernel dell'operatore pertinente nella directory tensorflow/core/kernels, puoi cercare il percorso del codice sorgente, che contiene la seguente dichiarazione del kernel con il nome dell'operatore:

REGISTER_KERNEL_BUILDER(Name("StringToNumber")                 \
                            .Device(DEVICE_CPU)                \
                            .TypeConstraint<type>("out_type"), \
                        StringToNumberOp<type>)

Se nella directory tensorflow/core/kernels sono presenti file di intestazione, necessari nel codice sorgente del kernel dell'operatore, devi aggiungere il file di intestazione alla regola Build portable_extended_ops_headers nel seguente modo:

filegroup(
    name = "portable_extended_ops_headers",
    srcs = [
        ...
+   "string_util.h",

        ...
    ],
)

(2) Aggiungi il nome dell'operatore all'elenco degli operatori autorizzati.

L'elenco di quelli consentiti è definito in tensorflow/lite/delegates/flex/allowlisted_flex_ops.cc. Il nome dell'operatore di TensorFlow core deve essere elencato per essere consentito tramite l'opzione Seleziona TF.

static const std::set<std::string>* allowlisted_flex_ops =
    new std::set<std::string>({
        ...
+   "StringToNumber",

        ...
    });

Poiché l'elenco riportato sopra è in ordine alfabetico, garantisce di aver posizionato il nome nel posto giusto.
