TensorFlow Extended'a (TFX) Bileşen Bileşen Giriş
 TensorFlow.org'da görüntüleyin |  Google Colab'da çalıştırın |  Kaynağı GitHub'da görüntüleyin |  Not defterini indir |
Bu Colab tabanlı öğretici, TensorFlow Extended'ın (TFX) her yerleşik bileşenini etkileşimli olarak gözden geçirecektir.
Veri alımından bir modeli sunmaya kadar, uçtan uca bir makine öğrenimi hattındaki her adımı kapsar.
İşiniz bittiğinde, bu not defterinin içeriği, Apache Airflow ve Apache Beam ile düzenleyebileceğiniz TFX ardışık düzen kaynak kodu olarak otomatik olarak dışa aktarılabilir.
Arka plan
Bu not defteri, TFX'in bir Jupyter/Colab ortamında nasıl kullanılacağını gösterir. Burada, interaktif bir not defterinde Chicago Taksi örneğini inceleyeceğiz.
Etkileşimli bir not defterinde çalışmak, bir TFX işlem hattının yapısına aşina olmanın yararlı bir yoludur. Hafif bir geliştirme ortamı olarak kendi işlem hatlarınızı geliştirirken de yararlıdır, ancak etkileşimli not defterlerinin düzenlenme biçiminde ve meta veri yapılarına nasıl eriştiklerinde farklılıklar olduğunu bilmelisiniz.
Orkestrasyon
TFX'in üretim dağıtımında, TFX bileşenlerinin önceden tanımlanmış bir işlem hattı grafiğini düzenlemek için Apache Airflow, Kubeflow Pipelines veya Apache Beam gibi bir düzenleyici kullanacaksınız. Etkileşimli bir not defterinde, not defterinin kendisi, siz not defteri hücrelerini yürütürken her TFX bileşenini çalıştıran düzenleyicidir.
meta veri
TFX'in üretim dağıtımında, ML Meta Verileri (MLMD) API'si aracılığıyla meta verilere erişeceksiniz. MLMD, meta veri özelliklerini MySQL veya SQLite gibi bir veritabanında saklar ve meta veri yüklerini dosya sisteminiz gibi kalıcı bir depoda saklar. İnteraktif bir notebook olarak, özellikleri ve yükleri hem de geçici bir SQLite veritabanında saklanır /tmp Jupyter dizüstü veya CoLab sunucudaki dizinin.
Kurmak
Öncelikle gerekli paketleri kurup import ediyoruz, yolları ayarlıyoruz ve verileri indiriyoruz.
Pip'i Yükselt
Yerel olarak çalışırken bir sistemde Pip'i yükseltmekten kaçınmak için Colab'da çalıştığımızdan emin olun. Yerel sistemler elbette ayrı ayrı yükseltilebilir.
try:
import colab
!pip install --upgrade pip
except:
pass
TFX'i yükleyin
pip install -U tfx
Çalışma zamanını yeniden başlattınız mı?
Google Colab kullanıyorsanız, yukarıdaki hücreyi ilk kez çalıştırdığınızda, çalışma zamanını yeniden başlatmanız gerekir (Çalışma Zamanı > Çalışma zamanını yeniden başlat...). Bunun nedeni Colab'ın paketleri yükleme şeklidir.
Paketleri içe aktar
Standart TFX bileşen sınıfları dahil gerekli paketleri içe aktarıyoruz.

InteractiveContext'i oluşturun
Son olarak, bu not defterinde TFX bileşenlerini etkileşimli olarak çalıştırmamıza izin verecek bir InteractiveContext oluşturuyoruz.

# InteractiveContext. Calls to InteractiveContext are no-ops outside of the

Şimdi bu ExampleGen verilerini sindirerek bittikten sonraki adım veri analizidir.
İstatistikGen
StatisticsGen mansap bileşenleri veri analizi için veri kümesi, hem de için kullanımı üzerinde bileşen değerlerini hesaplar istatistikleri. Kullandığı TensorFlow Veri Doğrulama kütüphane.
StatisticsGen girdi olarak biz sadece kullanılarak yutulur veri kümesi alır ExampleGen .
statistics_gen = tfx.components.StatisticsGen(
examples=example_gen.outputs['examples'])
context.run(statistics_gen)

Sonra StatisticsGen çalıştırılması tamamlandıktan biz outputted istatistiklerini görüntüleyebilir. Farklı arsalarla oynamayı deneyin!
context.show(statistics_gen.outputs['statistics'])
ŞemaGen
SchemaGen bileşeni veri istatistiklere dayalı bir şema oluşturur. (Bir şema beklenen sınırları, türlerini ve veri kümesi özelliklerin özelliklerini tanımlar.) Aynı zamanda kullandığı TensorFlow Veri Doğrulama kütüphane.
SchemaGen biz oluşturduğu istatistik girdi olarak alacak StatisticsGen varsayılan olarak eğitim bölünmüş bakarak.
schema_gen = tfx.components.SchemaGen(
statistics=statistics_gen.outputs['statistics'],
infer_feature_shape=False)
context.run(schema_gen)
INFO:absl:Excluding no splits because exclude_splits is not set.

INFO:absl:Running publisher for SchemaGen INFO:absl:MetadataStore with DB connection initialized
Sonra SchemaGen çalışmasını bitirdiğinde, bir tablo olarak oluşturulan şema benzetebiliriz.
context.show(schema_gen.outputs['schema'])
Veri kümenizdeki her özellik, özelliklerinin yanında şema tablosunda bir satır olarak görünür. Şema ayrıca kategorik bir özelliğin üstlendiği, etki alanı olarak gösterilen tüm değerleri de yakalar.
Şemaları hakkında daha fazla bilgi edinmek için bkz SchemaGen belgelerine .
Örnek Doğrulayıcı
ExampleValidator bileşen şeması tarafından tanımlanan beklentilere dayalı, sizin verilerdeki anormallikleri tespit eder. Ayrıca kullandığı TensorFlow Veri Doğrulama kütüphane.
ExampleValidator gelen girdi olarak istatistik alacak StatisticsGen ve gelen şema SchemaGen .
example_validator = tfx.components.ExampleValidator(
statistics=statistics_gen.outputs['statistics'],
schema=schema_gen.outputs['schema'])
context.run(example_validator)
INFO:absl:Excluding no splits because exclude_splits is not set.

INFO:absl:Running publisher for ExampleValidator INFO:absl:MetadataStore with DB connection initialized
Sonra ExampleValidator çalışmasını bitirdiğinde, bir tablo olarak anormallikleri oluşturulabiliyor.
context.show(example_validator.outputs['anomalies'])
Anomaliler tablosunda herhangi bir anormallik olmadığını görebiliriz. Bu, analiz ettiğimiz ilk veri seti ve şema buna göre ayarlandığından, beklediğimiz şey bu. Bu şemayı gözden geçirmelisiniz -- beklenmeyen herhangi bir şey, verilerde bir anormallik olduğu anlamına gelir. Şema gözden geçirildikten sonra, gelecekteki verileri korumak için kullanılabilir ve burada üretilen anormallikler, model performansında hata ayıklamak, verilerinizin zaman içinde nasıl geliştiğini anlamak ve veri hatalarını belirlemek için kullanılabilir.
dönüştürmek
Transform eğitim ve hizmet veren her ikisi için bileşen gerçekleştirdiği özellik mühendislik. Kullandığı TensorFlow Transform kütüphanesi.
Transform girdi olarak veri alır ExampleGen , şemadan SchemaGen , hem de kullanıcı tarafından belirlenen bir kod dönüşümü içeren bir modül.
Diyelim bir örnek görmek kullanıcı tanımlı (TensorFlow bir giriş için API'leri Transform aşağıdaki kodu Transform öğretici bakınız ). İlk olarak, özellik mühendisliği için birkaç sabit tanımlıyoruz:

Değerlendirici
Evaluator bileşeni değerlendirme kümesi üzerinden modeli performans ölçümlerini hesaplar. Bu kullanan TensorFlow Modeli Analizi kitaplığı. Evaluator ayrıca isteğe bağlı olarak yeni eğitilmiş modeli daha iyi önceki modele göre olduğunu doğrulamak. Bu, bir modeli her gün otomatik olarak eğitip doğrulayabileceğiniz bir üretim hattı ayarında kullanışlıdır. Böylece bu defter, biz sadece bir modeli eğitmek Evaluator otomatik olarak "iyi" olarak modelini etiketleyecektir.
Evaluator girdi olarak veri alacak ExampleGen gelen eğitimli modeli Trainer ve dilimleme yapılandırmayı. Dilimleme yapılandırması, metriklerinizi özellik değerlerine göre dilimlemenize olanak tanır (örneğin, modeliniz sabah 8'de başlayıp akşam 8'de başlayan taksi yolculuklarında nasıl performans gösterir?). Aşağıda bu yapılandırmanın bir örneğine bakın:
eval_config = tfma.EvalConfig(

# This assumes a serving model with signature 'serving_default'. If
# using estimator based EvalSavedModel, add signature_name: 'eval' and

preprocessing_function_names=['transform_features'],
)
],
metrics_specs=[
tfma.MetricsSpec(
# The metrics added here are in addition to those saved with the
# model (assuming either a keras model or EvalSavedModel is used).
# Any metrics added into the saved model (for example using
# model.compile(..., metrics=[...]), etc) will be computed
# automatically.
# To add validation thresholds for metrics saved with the model,
# add them keyed by metric name to the thresholds map.
metrics=[
tfma.MetricConfig(class_name='ExampleCount'),
tfma.MetricConfig(class_name='BinaryAccuracy',
threshold=tfma.MetricThreshold(
value_threshold=tfma.GenericValueThreshold(
lower_bound={'value': 0.5}),
# Change threshold will be ignored if there is no
# baseline model resolved from MLMD (first run).
change_threshold=tfma.GenericChangeThreshold(

Dilimlenmiş değerlendirme metriklerinin görselleştirmesini görmek için doğrudan TensorFlow Model Analizi kitaplığını çağırabiliriz.
import tensorflow_model_analysis as tfma
# Get the TFMA output result path and load the result.
PATH_TO_RESULT = evaluator.outputs['evaluation'].get()[0].uri
tfma_result = tfma.load_eval_result(PATH_TO_RESULT)

tfma.view.render_slicing_metrics(
tfma_result, slicing_column='trip_start_hour')

Bu görselleştirme aynı ölçümleri gösterir, ancak her özellik değerinde hesaplanan trip_start_hour tamamı yerine değerlendirme sette.
TensorFlow Model Analizi, Adalet Göstergeleri ve bir zaman serisi model performansının çizilmesi gibi diğer birçok görselleştirmeyi destekler. Daha fazla bilgi için bkz öğretici .
