TFX 파이프라인 및 TensorFlow Transform을 사용한 기능 엔지니어링

TFX 파이프라인을 사용하여 입력 데이터를 변환하고 모델을 학습시킵니다.

이 노트북 기반 자습서에서는 TFX 파이프라인을 생성 및 실행하여 원시 입력 데이터를 수집하고 ML 교육에 적절하게 사전 처리합니다. 이 노트북은 우리가 내장 된 TFX 파이프 라인을 기반으로 TFX 파이프 라인 및 TensorFlow 데이터 유효성 검사 자습서를 사용하여 데이터 유효성 검사 . 아직 읽지 않았다면 이 노트북을 계속 진행하기 전에 읽어야 합니다.

피쳐 엔지니어링으로 데이터의 예측 품질을 높이거나 차원을 줄일 수 있습니다. TFX를 사용할 때의 이점 중 하나는 변환 코드를 한 번만 작성하면 훈련/서빙 편향을 피하기 위해 결과 변환이 훈련과 제공 간에 일관된다는 것입니다.

우리는이 추가됩니다 Transform 파이프 라인 구성 요소입니다. 변환 구성 요소는 사용하여 구현됩니다 tf.transform의 라이브러리를.

참조하시기 바랍니다 TFX 파이프 라인은 이해 TFX에서 다양한 개념에 대해 더 배울 수 있습니다.

설정

먼저 TFX Python 패키지를 설치하고 모델에 사용할 데이터 세트를 다운로드해야 합니다.

핍 업그레이드

로컬에서 실행할 때 시스템에서 Pip를 업그레이드하지 않으려면 Colab에서 실행 중인지 확인하세요. 물론 로컬 시스템은 별도로 업그레이드할 수 있습니다.

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

TFX 설치

pip install -U tfx

런타임을 다시 시작했습니까?

Google Colab을 사용하는 경우 위의 셀을 처음 실행할 때 위의 "RESTART RUNTIME" 버튼을 클릭하거나 "런타임 > 런타임 다시 시작..." 메뉴를 사용하여 런타임을 다시 시작해야 합니다. Colab이 패키지를 로드하는 방식 때문입니다.

TensorFlow 및 TFX 버전을 확인하세요.

import tensorflow as tf
print('TensorFlow version: {}'.format(tf.__version__))
from tfx import v1 as tfx
print('TFX version: {}'.format(tfx.__version__))
TensorFlow version: 2.5.1
TFX version: 1.2.0

변수 설정

파이프라인을 정의하는 데 사용되는 몇 가지 변수가 있습니다. 원하는 대로 이러한 변수를 사용자 정의할 수 있습니다. 기본적으로 파이프라인의 모든 출력은 현재 디렉터리 아래에 생성됩니다.

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.

예시 데이터 준비

TFX 파이프라인에서 사용할 예제 데이터 세트를 다운로드합니다. 우리가 사용하고있는 데이터 세트는 팔머 펭귄 데이터 세트 .

그러나, 이미 전처리 된 데이터 집합을 사용 이전 튜토리얼과는 달리, 우리는 원시 팔머 펭귄 데이터 세트를 사용합니다.

TFX ExampleGen 구성 요소는 디렉터리에서 입력을 읽기 때문에 디렉터리를 만들고 데이터 집합을 디렉터리에 복사해야 합니다.

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-data3sjvggnf/data.csv', <http.client.HTTPMessage at 0x7f419aea05d0>)

원시 데이터가 어떻게 보이는지 빠르게 살펴보십시오.

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

로 표현되는 값이 누락 된 일부 항목이 있습니다 NA . 이 자습서에서는 해당 항목만 삭제합니다.

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

펭귄을 묘사하는 7가지 특징을 볼 수 있어야 합니다. 우리는 이전 튜토리얼과 동일한 기능 세트('culmen_length_mm', 'culmen_depth_mm', 'flipper_length_mm', 'body_mass_g')를 사용하고 펭귄의 '종'을 예측할 것입니다.

유일한 차이점은 입력 데이터가 사전 처리되지 않는다는 것입니다. 이 튜토리얼에서는 'island' 또는 'sex'와 같은 다른 기능을 사용하지 않습니다.

스키마 파일 준비

에서 설명한 바와 같이 TFX 파이프 라인 및 TensorFlow 데이터 유효성 검사 자습서를 사용하여 데이터 검증 , 우리는 데이터 세트에 대한 스키마 파일이 필요합니다. 데이터 세트가 이전 자습서와 다르기 때문에 다시 생성해야 합니다. 이 자습서에서는 이러한 단계를 건너뛰고 준비된 스키마 파일만 사용합니다.

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 0x7f419aeb0490>)

이 스키마 파일은 수동 변경 없이 이전 자습서와 동일한 파이프라인으로 생성되었습니다.

파이프라인 생성

TFX 파이프라인은 Python API를 사용하여 정의됩니다. 우리는 추가 할 것이다 Transform 우리가에서 만든 파이프 라인 구성 요소 데이터 유효성 검사 튜토리얼 .

변환 컴포넌트는 데이터 입력에서 요구 ExampleGen 성분과의 스키마 SchemaGen 성분을, 그리고는 "그래프 변환"생성한다. 출력은 사용됩니다 Trainer 구성 요소입니다. 변환은 선택적으로 변환 후 구체화된 데이터인 "변환된 데이터"를 추가로 생성할 수 있습니다. 그러나 이 튜토리얼에서는 중간 변환 데이터를 구체화하지 않고 훈련 중에 데이터를 변환합니다.

주의 할 점은 우리가 파이썬 함수를 정의 할 필요가 있다는 것입니다 preprocessing_fn 입력 데이터를 변환 할 방법을 설명 할 수있다. 이는 모델 정의를 위한 사용자 코드도 필요로 하는 Trainer 구성 요소와 유사합니다.

전처리 및 학습 코드 작성

두 개의 Python 함수를 정의해야 합니다. 하나는 Transform용이고 하나는 Trainer용입니다.

전처리_fn

변환 구성 요소는 기능을 이름을 찾을 수 preprocessing_fn 우리가 그랬던 것처럼 주어진 모듈 파일에 Trainer 구성 요소입니다. 또한 사용하여 특정 기능을 지정할 수 있습니다 preprocessing_fn 매개 변수 변형 구성 요소를.

이 예에서는 두 가지 유형의 변환을 수행합니다. 같은 연속 숫자 기능에 대한 culmen_length_mmbody_mass_g , 우리는 사용하여 이러한 값을 정상화 tft.scale_to_z_score의 기능을. 레이블 기능의 경우 문자열 레이블을 숫자 인덱스 값으로 변환해야 합니다. 우리는 사용 tf.lookup.StaticHashTable 변환.

쉽게 변형 필드를 식별하기 위해, 우리는 추가 _xf 변환하는 기능 이름에 접미사.

run_fn

모델 자체는 이전 자습서와 거의 동일하지만 이번에는 Transform 구성 요소의 변환 그래프를 사용하여 입력 데이터를 변환합니다.

이전 튜토리얼과 비교하여 한 가지 더 중요한 차이점은 이제 모델의 계산 그래프뿐만 아니라 Transform 컴포넌트에서 생성되는 전처리를 위한 변환 그래프가 포함된 서빙용 모델을 내보낸다는 것입니다. 들어오는 요청을 처리하는 데 사용할 별도의 함수를 정의해야 합니다. 동일한 기능 것을 볼 수 있습니다 _apply_preprocessing 훈련 데이터와 서빙 요청에 모두 사용되었다.

이제 TFX 파이프라인을 구축하기 위한 모든 준비 단계를 완료했습니다.

파이프라인 정의 작성

또한 사용하여 생성 된 모델의 서명을 확인할 수 있습니다 saved_model_cli 도구를 .

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:

Method name is: tensorflow/serving/predict

우리는 정의하기 때문에 serving_default 우리 자신과 serve_tf_examples_fn 기능이 하나의 문자열을 사용 서명을 보여줍니다. 이 문자열은 tf.Examples의 직렬화 된 문자열과 함께 구문 분석됩니다 tf.io.parse_example () 우리가 이전에 정의 된 (더 tf.Examples에 대해 자세히 알아보기 기능 여기 ).
