برنامج تعليمي بسيط لخط أنابيب TFX باستخدام مجموعة بيانات Penguin

تنظيم صفحاتك في مجموعات يمكنك حفظ المحتوى وتصنيفه حسب إعداداتك المفضّلة.

برنامج تعليمي قصير لتشغيل خط أنابيب TFX بسيط.

في هذا البرنامج التعليمي المستند إلى الكمبيوتر المحمول ، سننشئ ونشغل خط أنابيب TFX لنموذج تصنيف بسيط. سيتألف خط الأنابيب من ثلاثة مكونات أساسية لـ TFX: ExampleGen ، و Trainer ، و Pusher. يتضمن خط الأنابيب الحد الأدنى من سير عمل ML مثل استيراد البيانات وتدريب نموذج وتصدير النموذج المدرب.

يرجى الاطلاع على فهم TFX خطوط الأنابيب لمعرفة المزيد عن مفاهيم مختلفة في TFX.

يثبت

نحتاج أولاً إلى تثبيت حزمة TFX Python وتنزيل مجموعة البيانات التي سنستخدمها لنموذجنا.

ترقية النقطة

لتجنب ترقية Pip في نظام عند التشغيل محليًا ، تحقق للتأكد من أننا نعمل في Colab. يمكن بالطبع ترقية الأنظمة المحلية بشكل منفصل.

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

قم بتثبيت TFX

pip install -U tfx

هل أعدت تشغيل وقت التشغيل؟

إذا كنت تستخدم Google Colab ، في المرة الأولى التي تقوم فيها بتشغيل الخلية أعلاه ، يجب إعادة تشغيل وقت التشغيل بالنقر فوق الزر "RESTART RUNTIME" أعلاه أو باستخدام قائمة "Runtime> Restart runtime ...". هذا بسبب الطريقة التي يقوم بها كولاب بتحميل الحزم.

تحقق من إصدارات TensorFlow و 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

قم بإعداد المتغيرات

هناك بعض المتغيرات المستخدمة لتحديد خط الأنابيب. يمكنك تخصيص هذه المتغيرات كما تريد. بشكل افتراضي ، سيتم إنشاء كل الإخراج من خط الأنابيب ضمن الدليل الحالي.

import os

PIPELINE_NAME = "penguin-simple"

# 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.

تحضير البيانات النموذجية

سنقوم بتنزيل نموذج مجموعة البيانات لاستخدامه في خط أنابيب TFX الخاص بنا. مجموعة البيانات التي نستخدمها هي بالمر البطاريق مجموعة البيانات التي تستخدم أيضا في غيرها من الأمثلة TFX .

توجد أربع سمات رقمية في مجموعة البيانات هذه:

  • culmen_length_mm
  • culmen_depth_mm
  • الزعنفة_length_mm
  • body_mass_g

تم بالفعل تسوية جميع الميزات ليكون لها نطاق [0،1]. سوف نبني نموذج التصنيف الذي يتنبأ species من طيور البطريق.

نظرًا لأن TFX ExampleGen تقرأ المدخلات من دليل ، نحتاج إلى إنشاء دليل ونسخ مجموعة البيانات إليه.

import urllib.request
import tempfile

DATA_ROOT = tempfile.mkdtemp(prefix='tfx-data')  # Create a temporary directory.
_data_url = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/penguin/data/labelled/penguins_processed.csv'
_data_filepath = os.path.join(DATA_ROOT, "data.csv")
urllib.request.urlretrieve(_data_url, _data_filepath)
('/tmp/tfx-dataijanq9u3/data.csv', <http.client.HTTPMessage at 0x7f487953d110>)

ألق نظرة سريعة على ملف CSV.

يجب أن تكون قادرًا على رؤية خمس قيم. species هي واحدة من 0 أو 1 أو 2، ويجب على جميع الميزات الأخرى لديها قيم بين 0 و 1.

قم بإنشاء خط أنابيب

يتم تعريف خطوط أنابيب TFX باستخدام واجهات برمجة تطبيقات Python. سنحدد خط الأنابيب الذي يتكون من المكونات الثلاثة التالية.

  • CsvExampleGen: يقرأ في ملفات البيانات ويحولها إلى تنسيق داخلي TFX لمزيد من المعالجة. هناك عدة ExampleGen الصورة لمختلف الصيغ. في هذا البرنامج التعليمي ، سوف نستخدم CsvExampleGen الذي يأخذ إدخال ملف CSV.
  • المدرب: يقوم بتدريب نموذج ML. عنصر مدرب يتطلب رمز تعريف نموذج من المستخدمين. يمكنك استخدام TensorFlow واجهات برمجة التطبيقات لتحديد كيفية تدريب نموذج وحفظه في شكل نموذج _saved.
  • دافع: ينسخ النموذج المدرب خارج خط أنابيب TFX. عنصر انتهازي يمكن اعتبار عملية التوزيع من طراز ML المدربين.

قبل تحديد خط الأنابيب فعليًا ، نحتاج إلى كتابة رمز نموذجي لمكون المدرب أولاً.

اكتب كود التدريب النموذجي

سننشئ نموذج DNN بسيطًا للتصنيف باستخدام TensorFlow Keras API. سيتم حفظ رمز التدريب النموذجي هذا في ملف منفصل.

في هذا البرنامج التعليمي سوف نستخدم عام المدرب من TFX التي تدعم النماذج القائمة Keras. تحتاج إلى كتابة ملف بيثون التي تحتوي على run_fn وظيفة، وهو نقطة الدخول لل Trainer المكون.

لقد أكملت الآن جميع خطوات الإعداد لإنشاء خط أنابيب TFX.

نحدد وظيفة لإنشاء خط أنابيب TFX. A Pipeline يمثل الكائن خط أنابيب TFX التي يمكن تشغيلها باستخدام واحدة من شبكات الأنابيب تزامن التي تدعم TFX.

قم بتشغيل خط الأنابيب

تدعم TFX عدة منسقين لتشغيل خطوط الأنابيب. في هذا البرنامج التعليمي سوف نستخدم LocalDagRunner التي يتم تضمينها في TFX بيثون حزمة وتدير خطوط الأنابيب على البيئة المحلية. غالبًا ما نطلق على خطوط أنابيب TFX اسم "DAGs" والتي تعني الرسم البياني غير الدوري الموجه.

LocalDagRunner توفر تكرارات سريعة لو developemnt والتصحيح. تدعم TFX أيضًا منسقي الأوركسترا الآخرين بما في ذلك خطوط أنابيب Kubeflow و Apache Airflow المناسبة لحالات استخدام الإنتاج.

انظر TFX على الغيمة AI منصة خطوط الأنابيب أو TFX تدفق الهواء دروس لتعلم المزيد حول أنظمة تزامن أخرى.

ونحن الآن إنشاء LocalDagRunner واجتياز Pipeline كائن تم إنشاؤه من وظيفة حددنا بالفعل.
