Progettazione di feature utilizzando TFX Pipeline e TensorFlow Transform

Trasforma i dati di input e traccia un modello con una pipeline TFX.

In questo tutorial basato su notebook, creeremo ed eseguiremo una pipeline TFX per acquisire dati di input non elaborati e preelaborarli in modo appropriato per l'addestramento ML. Questo notebook è basato sul gasdotto TFX abbiamo costruito nella validazione dei dati utilizzando TFX Pipeline e tensorflow Data Validation Tutorial . Se non l'hai ancora letto, dovresti leggerlo prima di procedere con questo quaderno.

Puoi aumentare la qualità predittiva dei tuoi dati e/o ridurre la dimensionalità con l'ingegneria delle funzionalità. Uno dei vantaggi dell'utilizzo di TFX è che si scriverà il codice di trasformazione una volta e le trasformazioni risultanti saranno coerenti tra l'addestramento e l'elaborazione per evitare lo squilibrio tra addestramento e pubblicazione.

Noi aggiungeremo un Transform componente alla pipeline. Il componente Transform è implementato utilizzando il tf.transform biblioteca.

Si prega di consultare Capire TFX Pipelines per conoscere meglio i vari concetti in TFX.

Impostare

Per prima cosa dobbiamo installare il pacchetto TFX Python e scaricare il set di dati che utilizzeremo per il nostro modello.

Aggiorna Pip

Per evitare di aggiornare Pip in un sistema durante l'esecuzione in locale, verificare che stiamo eseguendo in Colab. I sistemi locali possono ovviamente essere aggiornati separatamente.

try:
  import colab
  !pip install --upgrade pip
except:
  pass

Installa TFX

pip install -U tfx

Hai riavviato il runtime?

Se stai utilizzando Google Colab, la prima volta che esegui la cella in alto, devi riavviare il runtime facendo clic sul pulsante "RIAVVIA RUNTIME" sopra o utilizzando il menu "Runtime > Riavvia runtime ...". Ciò è dovuto al modo in cui Colab carica i pacchetti.

Controlla le versioni TensorFlow e TFX.

import tensorflow as tf
print('TensorFlow version: {}'.format(tf.__version__))
from tfx import v1 as tfx
print('TFX version: {}'.format(tfx.__version__))
TensorFlow version: 2.6.2
TFX version: 1.4.0

Imposta variabili

Ci sono alcune variabili usate per definire una pipeline. Puoi personalizzare queste variabili come desideri. Per impostazione predefinita, tutto l'output dalla pipeline verrà generato nella directory corrente.

import os

PIPELINE_NAME = "penguin-transform"

# Output directory to store artifacts generated from the pipeline.
PIPELINE_ROOT = os.path.join('pipelines', PIPELINE_NAME)
# Path to a SQLite DB file to use as an MLMD storage.
METADATA_PATH = os.path.join('metadata', PIPELINE_NAME, 'metadata.db')
# Output directory where created models from the pipeline will be exported.
SERVING_MODEL_DIR = os.path.join('serving_model', PIPELINE_NAME)

from absl import logging
logging.set_verbosity(logging.INFO)  # Set default logging level.

Prepara dati di esempio

Scaricheremo il set di dati di esempio da utilizzare nella nostra pipeline TFX. Il set di dati che stiamo usando è Palmer Penguins set di dati .

Tuttavia, a differenza tutorial precedenti che hanno usato un set di dati già pre-elaborato, useremo il grezzo dataset Palmer Penguins.

Poiché il componente TFX ExampleGen legge gli input da una directory, è necessario creare una directory e copiarvi il set di dati.

import urllib.request
import tempfile

DATA_ROOT = tempfile.mkdtemp(prefix='tfx-data')  # Create a temporary directory.
_data_path = 'https://storage.googleapis.com/download.tensorflow.org/data/palmer_penguins/penguins_size.csv'
_data_filepath = os.path.join(DATA_ROOT, "data.csv")
urllib.request.urlretrieve(_data_path, _data_filepath)
('/tmp/tfx-dataacmxfq9f/data.csv', <http.client.HTTPMessage at 0x7f5b0ab1bf10>)

Dai una rapida occhiata a come appaiono i dati grezzi.

head {_data_filepath}

Adelie,Torgersen,39.2,19.6,195,4675,MALE
Adelie,Torgersen,34.1,18.1,193,3475,NA

Vi sono alcune voci con valori che sono rappresentati come mancanti NA . Elimineremo semplicemente quelle voci in questo tutorial.

sed -i '/\bNA\b/d' {_data_filepath}
head {_data_filepath}
species,island,culmen_length_mm,culmen_depth_mm,flipper_length_mm,body_mass_g,sex

Adelie,Torgersen,41.1,17.6,182,3200,FEMALE
Adelie,Torgersen,38.6,21.2,191,3800,MALE

Dovresti essere in grado di vedere sette caratteristiche che descrivono i pinguini. Utilizzeremo lo stesso set di funzionalità dei tutorial precedenti - 'culmen_length_mm', 'culmen_depth_mm', 'flipper_length_mm', 'body_mass_g' - e predire la 'specie' di un pinguino.

L'unica differenza sarà che i dati di input non sono preelaborati. Nota che non utilizzeremo altre funzionalità come "isola" o "sesso" in questo tutorial.

Prepara un file di schema

Come descritto nella validazione dei dati utilizzando TFX Pipeline e tensorflow Data Validation tutorial , abbiamo bisogno di un file di schema per il set di dati. Poiché il set di dati è diverso dall'esercitazione precedente, è necessario generarlo di nuovo. In questo tutorial, salteremo questi passaggi e utilizzeremo semplicemente un file di schema preparato.

import shutil

SCHEMA_PATH = 'schema'

_schema_uri = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/penguin/schema/raw/schema.pbtxt'
_schema_filename = 'schema.pbtxt'
_schema_filepath = os.path.join(SCHEMA_PATH, _schema_filename)

os.makedirs(SCHEMA_PATH, exist_ok=True)
urllib.request.urlretrieve(_schema_uri, _schema_filepath)
('schema/schema.pbtxt', <http.client.HTTPMessage at 0x7f5b0ab20f50>)

Questo file di schema è stato creato con la stessa pipeline dell'esercitazione precedente senza modifiche manuali.

Crea una pipeline

Le pipeline TFX sono definite utilizzando le API Python. Noi aggiungeremo Transform componente per l'oleodotto che abbiamo creato nel tutorial di Convalida dati .

Un componente Transform richiede dati di ingresso di un ExampleGen componente e uno schema da una SchemaGen componente, e produce una "trasformazione grafico". L'uscita sarà utilizzato in un Trainer componente. Transform può produrre facoltativamente anche "dati trasformati", ovvero i dati materializzati dopo la trasformazione. Tuttavia, trasformeremo i dati durante l'addestramento in questo tutorial senza la materializzazione dei dati trasformati intermedi.

Una cosa da notare è che abbiamo bisogno di definire una funzione Python, preprocessing_fn per descrivere come dati di input devono essere trasformati. È simile a un componente Trainer che richiede anche il codice utente per la definizione del modello.

Scrivi codice di pre-elaborazione e addestramento

Dobbiamo definire due funzioni Python. Uno per Transform e uno per Trainer.

preprocessing_fn

La componente Transform troverà una funzione chiamata preprocessing_fn nel data file del modulo come abbiamo fatto per Trainer componente. È inoltre possibile specificare una funzione specifica utilizzando il preprocessing_fn parametro del componente Transform.

In questo esempio, eseguiremo due tipi di trasformazione. Per le caratteristiche numerici continui come culmen_length_mm e body_mass_g , noi normalizzare questi valori utilizzando la tft.scale_to_z_score funzione. Per la funzione etichetta, dobbiamo convertire le etichette delle stringhe in valori di indice numerico. Useremo tf.lookup.StaticHashTable per la conversione.

Per identificare campi trasformati facilmente, aggiungiamo un _xf suffisso ai nomi funzionalità trasformate.

run_fn

Il modello stesso è quasi lo stesso dei tutorial precedenti, ma questa volta trasformeremo i dati di input utilizzando il grafico di trasformazione dal componente Trasforma.

Un'altra differenza importante rispetto al tutorial precedente è che ora esportiamo un modello per servire che include non solo il grafico di calcolo del modello, ma anche il grafico di trasformazione per la preelaborazione, che viene generato nel componente Trasforma. Dobbiamo definire una funzione separata che verrà utilizzata per servire le richieste in entrata. Si può vedere che la stessa funzione _apply_preprocessing è stato utilizzato per entrambi i dati di allenamento e la richiesta di servire.

Ora hai completato tutti i passaggi di preparazione per creare una pipeline TFX.

Scrivi una definizione di pipeline

Definiamo una funzione per creare una pipeline TFX. Un Pipeline oggetto rappresenta una pipeline TFX, che può essere eseguito utilizzando uno dei sistemi di conduttura orchestrazione che supporta TFX.

Dovresti vedere "INFO:absl:Component Pusher è terminato." se la pipeline è stata completata correttamente.

Il componente pusher spinge il modello addestrato per la SERVING_MODEL_DIR che è il serving_model/penguin-transform directory se non hai modificato le variabili nelle fasi precedenti. Puoi vedere il risultato dal browser dei file nel pannello di sinistra in Colab, o usando il seguente comando:

# List files in created model directory.
find {SERVING_MODEL_DIR}
serving_model/penguin-transform
serving_model/penguin-transform/1638699738
serving_model/penguin-transform/1638699738/keras_metadata.pb
serving_model/penguin-transform/1638699738/assets
serving_model/penguin-transform/1638699738/variables
serving_model/penguin-transform/1638699738/variables/variables.data-00000-of-00001
serving_model/penguin-transform/1638699738/variables/variables.index
serving_model/penguin-transform/1638699738/saved_model.pb

È inoltre possibile controllare la firma del modello generato utilizzando il saved_model_cli strumento .

saved_model_cli show --dir {SERVING_MODEL_DIR}/$(ls -1 {SERVING_MODEL_DIR} | sort -nr | head -1) --tag_set serve --signature_def serving_default
The given SavedModel SignatureDef contains the following input(s):
  inputs['examples'] tensor_info:
      dtype: DT_STRING
      shape: (-1)
      name: serving_default_examples:0
The given SavedModel SignatureDef contains the following output(s):
  outputs['output_0'] tensor_info:
      dtype: DT_FLOAT
      shape: (-1, 3)
      name: StatefulPartitionedCall_2:0
Method name is: tensorflow/serving/predict

Perché abbiamo definito serving_default con la nostra serve_tf_examples_fn funzione, gli spettacoli di firma che ci vuole una singola stringa. Questa stringa è una stringa serializzata tf.Examples e verrà analizzato con il tf.io.parse_example () funzionano come abbiamo definito in precedenza (ulteriori informazioni su tf.Examples qui ).

Possiamo caricare il modello esportato e provare alcune inferenze con alcuni esempi.

# Find a model with the latest timestamp.
model_dirs = (item for item in os.scandir(SERVING_MODEL_DIR) if item.is_dir())
model_path = max(model_dirs, key=lambda i: int(i.name)).path

loaded_model = tf.keras.models.load_model(model_path)
inference_fn = loaded_model.signatures['serving_default']

Il terzo elemento, che corrisponde alla specie 'Gentoo', dovrebbe essere il più grande tra i tre.
