Transforme os dados de entrada e traçando um modelo com um pipeline TFX.

Neste tutorial baseado em notebook, vamos criar e executar um pipeline TFX para ingerir dados de entrada brutos e pré-processá-los de forma adequada para o treinamento de ML. Este notebook é baseado no gasoduto TFX nós construímos na validação de dados usando TFX Pipeline e TensorFlow Validação de dados Tutorial . Se você ainda não leu este, deve lê-lo antes de prosseguir com este bloco de notas.

Você pode aumentar a qualidade preditiva de seus dados e / ou reduzir a dimensionalidade com a engenharia de recursos. Um dos benefícios de usar TFX é que você escreverá seu código de transformação uma vez, e as transformações resultantes serão consistentes entre o treinamento e a veiculação para evitar distorção de treinamento / veiculação.

Nós vamos adicionar um Transform componente para o pipeline. O componente Transform é implementado utilizando o tf.transform biblioteca.

Consulte Compreender TFX Pipelines para aprender mais sobre vários conceitos em TFX.

Configurar

Primeiro precisamos instalar o pacote TFX Python e baixar o conjunto de dados que usaremos em nosso modelo.

Atualizar Pip

Para evitar a atualização do Pip em um sistema quando executado localmente, verifique se estamos executando no Colab. É claro que os sistemas locais podem ser atualizados separadamente.

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

Instale TFX

pip install -U tfx

Você reiniciou o tempo de execução?

Se você estiver usando o Google Colab, na primeira vez que executar a célula acima, você deve reiniciar o tempo de execução clicando acima do botão "RESTART RUNTIME" ou usando o menu "Runtime> Restart runtime ...". Isso ocorre devido à maneira como o Colab carrega os pacotes.

Verifique as versões do 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

Configurar variáveis

Existem algumas variáveis ​​usadas para definir um pipeline. Você pode personalizar essas variáveis ​​como quiser. Por padrão, toda a saída do pipeline será gerada no diretório atual.

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.

Prepare dados de exemplo

Faremos o download do conjunto de dados de exemplo para uso em nosso pipeline TFX. O conjunto de dados que estamos usando é Palmer Penguins conjunto de dados .

No entanto, ao contrário de tutoriais anteriores que usaram um conjunto de dados já pré-processados, usaremos a matéria-dataset Palmer Penguins.

Como o componente TFX ExampleGen lê as entradas de um diretório, precisamos criar um diretório e copiar o conjunto de dados para ele.

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>)

Dê uma olhada rápida na aparência dos dados brutos.

head {_data_filepath}
species,island,culmen_length_mm,culmen_depth_mm,flipper_length_mm,body_mass_g,sex
Adelie,Torgersen,39.1,18.7,181,3750,MALE

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

Há algumas entradas com valores que são representados como desaparecidos NA . Apenas excluiremos essas entradas neste 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,39.1,18.7,181,3750,MALE
Adelie,Torgersen,39.5,17.4,186,3800,FEMALE
Adelie,Torgersen,40.3,18,195,3250,FEMALE
Adelie,Torgersen,36.7,19.3,193,3450,FEMALE
Adelie,Torgersen,39.3,20.6,190,3650,MALE

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

Você deve ser capaz de ver sete características que descrevem os pinguins. Usaremos o mesmo conjunto de recursos dos tutoriais anteriores - 'culmen_length_mm', 'culmen_depth_mm', 'flipper_length_mm', 'body_mass_g' - e preveremos a 'espécie' de um pinguim.

A única diferença será que os dados de entrada não são pré-processados. Observe que não usaremos outros recursos como 'ilha' ou 'sexo' neste tutorial.

Prepare um arquivo de esquema

Conforme descrito na validação de dados usando TFX Pipeline e TensorFlow Validação de dados Tutorial , precisamos de um arquivo de esquema para o conjunto de dados. Como o conjunto de dados é diferente do tutorial anterior, precisamos gerá-lo novamente. Neste tutorial, pularemos essas etapas e apenas usaremos um arquivo de esquema preparado.

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>)

Este arquivo de esquema foi criado com o mesmo pipeline do tutorial anterior, sem nenhuma alteração manual.

Crie um pipeline

Os pipelines TFX são definidos usando APIs Python. Nós vamos adicionar Transform componente para o gasoduto que criamos no tutorial Validação de dados .

Um componente Transform exige que os dados de entrada a partir de um ExampleGen componente e um esquema de um SchemaGen componente, e produz um "transformar gráfico". A saída será usado em um Trainer componente. Transform pode opcionalmente produzir "dados transformados", que são os dados materializados após a transformação. No entanto, transformaremos os dados durante o treinamento neste tutorial sem materialização dos dados transformados intermediários.

Uma coisa a notar é que precisamos definir uma função Python, preprocessing_fn para descrever como dados de entrada deve ser transformado. Isso é semelhante a um componente Trainer, que também requer código de usuário para a definição do modelo.

Escreva o código de pré-processamento e treinamento

Precisamos definir duas funções Python. Um para Transform e outro para Trainer.

preprocessing_fn

O componente Transform vai encontrar uma função chamada preprocessing_fn em determinado arquivo de módulo como fizemos para Trainer componente. Você também pode especificar uma função específica usando o preprocessing_fn parâmetro do componente Transform.

Neste exemplo, faremos dois tipos de transformação. Para recursos numéricos contínuos como culmen_length_mm e body_mass_g , vamos normalizar esses valores usando o tft.scale_to_z_score função. Para o recurso de rótulo, precisamos converter rótulos de string em valores de índice numérico. Usaremos tf.lookup.StaticHashTable para a conversão.

Para identificar campos transformados facilmente, nós anexar um _xf sufixo aos nomes dos recursos transformados.

run_fn

O modelo em si é quase o mesmo dos tutoriais anteriores, mas desta vez transformaremos os dados de entrada usando o gráfico de transformação do componente Transform.

Mais uma diferença importante em relação ao tutorial anterior é que agora exportamos um modelo para servir que inclui não apenas o gráfico de cálculo do modelo, mas também o gráfico de transformação para o pré-processamento, que é gerado no componente Transform. Precisamos definir uma função separada que será usada para atender às solicitações de entrada. Você pode ver que a mesma função _apply_preprocessing foi utilizada para ambos os dados de treinamento e o pedido de servir.

Agora você concluiu todas as etapas de preparação para construir um pipeline TFX.

Escreva uma definição de pipeline

Definimos uma função para criar um pipeline TFX. Um Pipeline objecto representa um oleoduto TFX, que pode ser executado utilizando um dos sistemas de tubagem que suporta orquestração TFX.

Você deverá ver "INFO: absl: Component Pusher is completed." se o pipeline foi concluído com sucesso.

O componente empurrador empurra o modelo treinado para o SERVING_MODEL_DIR que é o serving_model/penguin-transform diretório se você não alterou as variáveis nas etapas anteriores. Você pode ver o resultado do navegador de arquivos no painel esquerdo do Colab ou usando o seguinte 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/variables/variables.index
serving_model/penguin-transform/1638699738/saved_model.pb

Você também pode verificar a assinatura do modelo gerado usando o saved_model_cli ferramenta .

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

Porque nós definido serving_default com a nossa própria serve_tf_examples_fn função, os shows de assinatura que leva uma única cadeia. Essa seqüência é uma seqüência serializada do tf.Examples e será analisado com a tf.io.parse_example () função como definido anteriormente (saiba mais sobre tf.Examples aqui ).

Podemos carregar o modelo exportado e tentar algumas inferências com alguns exemplos.

# 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']

Espera-se que o terceiro elemento, que corresponde às espécies 'Gentoo', seja o maior entre três.
