ในบทช่วยสอนที่ใช้สมุดบันทึกนี้ เราจะสร้างและเรียกใช้ไปป์ไลน์ TFX เพื่อตรวจสอบข้อมูลอินพุตและสร้างแบบจำลอง ML โน๊ตบุ๊คนี้จะขึ้นอยู่กับท่อ TFX ที่เราสร้างขึ้นใน ง่าย TFX ท่อส่งกวดวิชา หากคุณยังไม่ได้อ่านบทช่วยสอนนั้น คุณควรอ่านก่อนดำเนินการกับสมุดบันทึกนี้
งานแรกใน data science หรือ ML project คือการทำความเข้าใจและทำความสะอาดข้อมูล ซึ่งรวมถึง:
- ทำความเข้าใจประเภทข้อมูล การแจกแจง และข้อมูลอื่นๆ (เช่น ค่าเฉลี่ย หรือจำนวนที่ไม่ซ้ำ) เกี่ยวกับคุณลักษณะแต่ละอย่าง
- การสร้างสคีมาเบื้องต้นที่อธิบาย data
- การระบุความผิดปกติและค่าที่ขาดหายไปในข้อมูลที่เกี่ยวกับสคีมาที่กำหนด
ในบทช่วยสอนนี้ เราจะสร้างไปป์ไลน์ TFX สองท่อ
ขั้นแรก เราจะสร้างไปป์ไลน์เพื่อวิเคราะห์ชุดข้อมูลและสร้างสคีมาเบื้องต้นของชุดข้อมูลที่กำหนด ท่อนี้จะรวมถึงสององค์ประกอบใหม่ StatisticsGen
และ SchemaGen
เมื่อเรามีสคีมาของข้อมูลที่เหมาะสมแล้ว เราจะสร้างไปป์ไลน์เพื่อฝึกโมเดลการจัดหมวดหมู่ ML ตามไปป์ไลน์จากบทช่วยสอนก่อนหน้า ในท่อนี้เราจะใช้สคีมาจากท่อครั้งแรกและเป็นองค์ประกอบใหม่ ExampleValidator
, การตรวจสอบข้อมูลของท่าน
สามองค์ประกอบใหม่ StatisticsGen, SchemaGen และ ExampleValidator เป็นส่วน TFX สำหรับการวิเคราะห์ข้อมูลและการตรวจสอบและพวกเขาจะดำเนินการโดยใช้ TensorFlow การตรวจสอบข้อมูล ห้องสมุด
โปรดดู เข้าใจ TFX วางท่อ เพื่อเรียนรู้เพิ่มเติมเกี่ยวกับแนวคิดต่าง ๆ ใน TFX
ติดตั้ง
ก่อนอื่นเราต้องติดตั้งแพ็คเกจ TFX Python และดาวน์โหลดชุดข้อมูลที่เราจะใช้สำหรับโมเดลของเรา
อัพเกรด Pip
เพื่อหลีกเลี่ยงการอัพเกรด Pip ในระบบเมื่อรันในเครื่อง ให้ตรวจสอบว่าเรากำลังทำงานใน Colab แน่นอนว่าระบบในพื้นที่สามารถอัพเกรดแยกกันได้
try:
import colab
!pip install --upgrade pip
except:
pass
ติดตั้ง TFX
pip install -U tfx
คุณรีสตาร์ทรันไทม์หรือไม่
หากคุณกำลังใช้ Google Colab ในครั้งแรกที่คุณเรียกใช้เซลล์ด้านบน คุณต้องรีสตาร์ทรันไทม์โดยคลิกที่ปุ่ม "RESTART RUNTIME" ด้านบน หรือใช้เมนู "Runtime > Restart runtime ..." นี่เป็นเพราะวิธีที่ Colab โหลดแพ็คเกจ
ตรวจสอบเวอร์ชัน TensorFlow และ 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
ตั้งค่าตัวแปร
มีตัวแปรบางตัวที่ใช้กำหนดไปป์ไลน์ คุณสามารถปรับแต่งตัวแปรเหล่านี้ได้ตามต้องการ โดยค่าเริ่มต้น เอาต์พุตทั้งหมดจากไปป์ไลน์จะถูกสร้างขึ้นภายใต้ไดเร็กทอรีปัจจุบัน
import os
# We will create two pipelines. One for schema generation and one for training.
SCHEMA_PIPELINE_NAME = "penguin-tfdv-schema"
PIPELINE_NAME = "penguin-tfdv"
# Output directory to store artifacts generated from the pipeline.
SCHEMA_PIPELINE_ROOT = os.path.join('pipelines', SCHEMA_PIPELINE_NAME)
PIPELINE_ROOT = os.path.join('pipelines', PIPELINE_NAME)
# Path to a SQLite DB file to use as an MLMD storage.
SCHEMA_METADATA_PATH = os.path.join('metadata', SCHEMA_PIPELINE_NAME,
'metadata.db')
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.
เตรียมข้อมูลตัวอย่าง
เราจะดาวน์โหลดชุดข้อมูลตัวอย่างเพื่อใช้ในไปป์ไลน์ TFX ของเรา ชุดข้อมูลที่เราใช้เป็น ชุดข้อมูลที่พาลเมอร์เพนกวิน ซึ่งยังใช้ในการอื่น ๆ ตัวอย่าง TFX
มีคุณลักษณะที่เป็นตัวเลขสี่ชุดในชุดข้อมูลนี้:
- culmen_length_mm
- culmen_deep_mm
- flipper_length_mm
- body_mass_g
คุณลักษณะทั้งหมดได้รับการทำให้เป็นมาตรฐานแล้วให้มีช่วง [0,1] เราจะสร้างรูปแบบการจัดชั้นที่คาดการณ์ species
ของนกเพนกวิน
เนื่องจากคอมโพเนนต์ TFX ExampleGen อ่านอินพุตจากไดเร็กทอรี เราจึงต้องสร้างไดเร็กทอรีและคัดลอกชุดข้อมูลไปยังไดเร็กทอรี

คุณควรจะเห็นคอลัมน์คุณลักษณะห้าคอลัมน์ species
เป็นหนึ่งใน 0, 1 หรือ 2 และคุณสมบัติอื่น ๆ ทุกคนควรจะมีค่าระหว่าง 0 และ 1 เราจะสร้างท่อส่ง TFX การวิเคราะห์ชุดข้อมูลนี้
สร้างสคีมาเบื้องต้น
ไปป์ไลน์ TFX ถูกกำหนดโดยใช้ Python API เราจะสร้างไปป์ไลน์เพื่อสร้างสคีมาจากตัวอย่างอินพุตโดยอัตโนมัติ สคีมานี้สามารถตรวจสอบได้โดยมนุษย์และปรับเปลี่ยนได้ตามต้องการ เมื่อสคีมาเสร็จสิ้นแล้ว สามารถใช้สำหรับการฝึกอบรมและการตรวจสอบตัวอย่างในงานในภายหลัง
นอกจากนี้ในการ CsvExampleGen
ซึ่งจะใช้ใน ง่าย TFX Pipeline สอน เราจะใช้ StatisticsGen
และ SchemaGen
:
- StatisticsGen คำนวณสถิติสำหรับชุดข้อมูล
- SchemaGen ตรวจสอบสถิติและสร้างสคีข้อมูลเบื้องต้น
ดูคำแนะนำสำหรับแต่ละส่วนประกอบหรือ ชิ้นส่วน TFX กวดวิชา ที่จะเรียนรู้เพิ่มเติมเกี่ยวกับองค์ประกอบเหล่านี้

ตรวจสอบผลลัพธ์ของไปป์ไลน์
เราได้ฝึกโมเดลการจำแนกประเภทสำหรับเพนกวิน และเรายังตรวจสอบความถูกต้องของตัวอย่างอินพุตในองค์ประกอบ ExampleValidator เราสามารถวิเคราะห์ผลลัพธ์จาก ExampleValidator เหมือนกับที่เราทำกับไปป์ไลน์ก่อนหน้า

with Metadata(metadata_connection_config) as metadata_handler:

ตัวอย่างความผิดปกติจาก ExampleValidator สามารถแสดงภาพได้เช่นกัน
visualize_artifacts(anomalies_artifacts)
คุณควรเห็น "ไม่พบความผิดปกติ" สำหรับตัวอย่างแต่ละส่วน เนื่องจากเราใช้ข้อมูลเดียวกันกับที่ใช้สำหรับการสร้างสคีมาในไปป์ไลน์นี้ จึงไม่คาดว่าจะมีความผิดปกติที่นี่ หากคุณเรียกใช้ไปป์ไลน์นี้ซ้ำๆ ด้วยข้อมูลขาเข้าใหม่ ExampleValidator ควรจะสามารถค้นหาความคลาดเคลื่อนระหว่างข้อมูลใหม่กับสคีมาที่มีอยู่ได้
หากพบความผิดปกติ คุณอาจตรวจสอบข้อมูลของคุณเพื่อดูว่ามีตัวอย่างใดที่ไม่เป็นไปตามสมมติฐานของคุณ เอาต์พุตจากส่วนประกอบอื่นๆ เช่น StatisticsGen อาจมีประโยชน์ อย่างไรก็ตาม ความผิดปกติใดๆ ที่พบจะไม่ปิดกั้นการดำเนินการไปป์ไลน์เพิ่มเติม
