מדריך רכיבי אומדן TFX

מבוא רכיב אחר רכיב ל-TensorFlow Extended (TFX)

הערה: מומלץ להפעיל הדרכה זו במחברת Colab, עם לא נדרשת התקנה! פשוט לחץ על "הפעל ב-Google Colab".

אזהרה: אומדים אינו מומלצים קוד חדש. אומד לרוץ v1.Session קוד -style וזה יותר קשה לכתוב בצורה נכונה, והוא יכול להתנהג באופן בלתי צפוי, במיוחד בשילוב עם קוד 2 TF. אומדים נופלים תחת שלנו ערבויות תאימות , אבל יקבלו שום תיקונים מלבד פגיעויות אבטחה. עיין במדריך ההעברה לפרטים.

מדריך זה מבוסס Colab יעבור באופן אינטראקטיבי על כל רכיב מובנה של TensorFlow Extended (TFX).

הוא מכסה כל שלב בצינור למידת מכונה מקצה לקצה, החל מהטמעת נתונים ועד לדחיפת מודל להגשה.

כשתסיים, ניתן לייצא את התוכן של מחברת זו באופן אוטומטי כקוד מקור של צינור TFX, אותו תוכל לתזמר עם Apache Airflow ו- Apache Beam.

הערה: מחברת זו ו- APIs הקשורים אליו הן ניסיוניות בפיתוח פעיל. צפויים שינויים גדולים בפונקציונליות, בהתנהגות ובמצגת.

רקע כללי

מחברת זו מדגים כיצד להשתמש ב-TFX בסביבת Jupyter/Colab. כאן, אנו עוברים על הדוגמה של Chicago Taxi במחברת אינטראקטיבית.

עבודה במחברת אינטראקטיבית היא דרך שימושית להכיר את המבנה של צינור TFX. זה שימושי גם כשאתה מבצע פיתוח של צינורות משלך כסביבת פיתוח קלת משקל, אבל עליך להיות מודע לכך שיש הבדלים באופן שבו מחברות אינטראקטיביות מסודרות, ובאופן שבו הן ניגשים לחפצי מטא נתונים.

תִזמוּר

בפריסת הפקה של TFX, תשתמש בתזמר כגון Apache Airflow, Kubeflow Pipelines או Apache Beam כדי לתזמן גרף צינור מוגדר מראש של רכיבי TFX. במחברת אינטראקטיבית, המחברת עצמה היא המתזמר, ומריץ כל רכיב TFX תוך כדי הפעלת תאי המחברת.

מטא נתונים

בפריסת ייצור של TFX, תוכל לגשת למטא נתונים דרך ה-API של ML Metadata (MLMD). MLMD מאחסן מאפייני מטא נתונים במסד נתונים כגון MySQL או SQLite, ומאחסן את עומסי המטא נתונים בחנות מתמשכת כגון במערכת הקבצים שלך. במחשב נייד אינטראקטיבי, הן נכסים מטענים מאוחסנים במסד נתונים SQLite חלוף ב /tmp המדריך בשרת מחברת או Colab Jupyter.

להכין

ראשית, אנו מתקינים ומייבאים את החבילות הדרושות, מגדירים נתיבים ומורידים נתונים.

שדרוג פיפ

כדי להימנע משדרוג Pip במערכת בעת הפעלה מקומית, בדוק כדי לוודא שאנו פועלים ב-Colab. ניתן כמובן לשדרג מערכות מקומיות בנפרד.

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

התקן TFX

הערה: ב- Google Colab, בגלל עדכוני חבילה, בפעם הראשונה שתפעיל את התא הזה עליך להפעיל מחדש את הריצה (Runtime> ריצה מחדש ...) **.

pip install -U tfx

הפעלת מחדש את זמן הריצה?

אם אתה משתמש ב-Google Colab, בפעם הראשונה שאתה מפעיל את התא שלמעלה, עליך להפעיל מחדש את זמן הריצה (Runtime > Restart runtime...). זה בגלל האופן שבו קולאב טוען חבילות.

ייבוא ​​חבילות

אנו מייבאים חבילות נחוצות, כולל מחלקות רכיבי TFX סטנדרטיות.

הורד נתונים לדוגמה

אנו מורידים את מערך הנתונים לדוגמה לשימוש בצינור ה-TFX שלנו.

בסיס הנתונים שאנו משתמשים בו הוא Taxi Trips הנתונים שפורסמו על ידי עיריית שיקגו. העמודות במערך נתונים זה הן:

אזור_קהילת_איסוף	דמי נסיעה	חודש_תחילת_טיול
שעה_התחלה_טיול	יום_התחלה_טיול	trip_start_timestamp
pickup_latitude	איסוף_אורך	dropoff_latitude
dropoff_longitude	trip_miles	אוסף_מפקד האוכלוסין
ערכת_מפקד_הורדה	סוג תשלום	חֶברָה
trip_seconds	אזור_קהילת ירידה	טיפים

עם מערך נתונים זה, נוכל לבנות מודל שמנבא את tips של טיול.

_data_root = tempfile.mkdtemp(prefix='tfx-data')
DATA_PATH = 'https://raw.githubusercontent.com/tensorflow/tfx/master/tfx/examples/chicago_taxi_pipeline/data/simple/data.csv'
_data_filepath = os.path.join(_data_root, "data.csv")
urllib.request.urlretrieve(DATA_PATH, _data_filepath)

צור את ה-InteractiveContext

לבסוף, אנו יוצרים InteractiveContext, שיאפשר לנו להפעיל רכיבי TFX באופן אינטראקטיבי במחברת זו.

# Here, we create an InteractiveContext using default parameters. This will
# use a temporary directory with an ephemeral ML Metadata database instance.
# To use your own pipeline root or database, the optional properties
# `pipeline_root` and `metadata_connection_config` may be passed to
# InteractiveContext. Calls to InteractiveContext are no-ops outside of the
# notebook.
context = InteractiveContext()

WARNING:absl:InteractiveContext pipeline_root argument not provided: using temporary directory /tmp/tfx-interactive-2021-12-05T10_59_24.898354-se36qxc4 as root for pipeline outputs.

הפעל רכיבי TFX באופן אינטראקטיבי

בתאים הבאים, אנו יוצרים רכיבי TFX אחד אחד, מפעילים כל אחד מהם ומדמיינים את חפצי הפלט שלהם.

דוגמה Gen

ExampleGen הרכיב הוא בדרך כלל בתחילת צינור TFX. זה יהיה:

1. פיצול נתונים לקבוצות אימון והערכה (כברירת מחדל, 2/3 אימון + 1/3 הערכה)
2. נתונים המר לתוך tf.Example הפורמט (למד עוד כאן )
3. העתיקו נתונים לתוך _tfx_root הספרייה עבור רכיבים אחרים גישה

ExampleGen לוקח כקלט את הנתיב אל מקור הנתונים שלך. במקרה שלנו, זה הוא _data_root הנתיב המכיל את CSV שהורידה.

הערה: המחברת הזאת, נוכל מופע רכיב אחד על אחד ולהפעיל אותם עם InteractiveContext.run() . לעומת זאת, במסגרת ההפקה, היינו לציין את כל המרכיבים מראש בתוך Pipeline להעביר את Orchestrator (ראה בניין מדריך צינור TFX ).

בואו לבחון את ממצאי הפלט של ExampleGen . רכיב זה מייצר שני חפצים, דוגמאות אימון ודוגמאות הערכה:

artifact = example_gen.outputs['examples'].get()[0]
print(artifact.split_names, artifact.uri)

["train", "eval"] /tmp/tfx-interactive-2021-12-05T10_59_24.898354-se36qxc4/CsvExampleGen/examples/1

אנו יכולים גם להסתכל על שלוש דוגמאות ההדרכה הראשונות:

# Get the URI of the output artifact representing the training examples, which is a directory
train_uri = os.path.join(example_gen.outputs['examples'].get()[0].uri, 'Split-train')

# Get the list of files in this directory (all compressed TFRecord files)
tfrecord_filenames = [os.path.join(train_uri, name)
                      for name in os.listdir(train_uri)]

# Create a `TFRecordDataset` to read these files
dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")

# Iterate over the first 3 records and decode them.
for tfrecord in dataset.take(3):
  serialized_example = tfrecord.numpy()
  example = tf.train.Example()
  example.ParseFromString(serialized_example)
  pp.pprint(example)

עכשיו ExampleGen סיימה בליעת הנתונים, השלב הבא הוא ניתוח נתונים.

סטטיסטיקה

StatisticsGen הסטטיסטיקה מחשב מרכיב מעל הנתונים שלך לניתוח נתונים, כמו גם לשימוש ברכיבים במורד הזרם. היא משתמשת אימות נתוני TensorFlow הספרייה.

StatisticsGen לוקח כקלט מערך הנתונים שאותו אנו פשוט לבלוע באמצעות ExampleGen .

כל תכונה במערך הנתונים שלך מופיעה כשורה בטבלת הסכימה, לצד המאפיינים שלה. הסכימה גם לוכדת את כל הערכים שתכונה קטגורית לוקחת על עצמה, מסומנים כתחום שלה.

כדי ללמוד עוד על סכימות, לראות בתיעוד SchemaGen .

אימות לדוגמה

ExampleValidator רכיב מזהה חריגות בנתונים שלך, המבוסס על ציפיות המוגדרים בסכימת. כמו כן משתמשת אימות נתונים TensorFlow הספרייה.

ExampleValidator ייקח כקלט הסטטיסטיקה מן StatisticsGen , ואת הסכימה מן SchemaGen .

בטבלת החריגות, אנו יכולים לראות שאין חריגות. זה מה שהיינו מצפים, שכן זהו מערך הנתונים הראשון שניתחנו והסכימה מותאמת אליו. עליך לעיין בסכימה זו -- כל דבר בלתי צפוי פירושו חריגה בנתונים. לאחר סקירה, הסכימה יכולה לשמש לשמירה על נתונים עתידיים, וניתן להשתמש בחריגות שנוצרו כאן כדי לנפות באגים בביצועי המודל, להבין כיצד הנתונים שלך מתפתחים לאורך זמן ולזהות שגיאות נתונים.

שינוי צורה

Transform הנדסת תכונה מבצע רכיב עבור שני אימונים והגשה. היא משתמשת TensorFlow Transform הספרייה.

Transform ייקח כקלט את הנתונים ExampleGen , של הסכמה SchemaGen , כמו גם מודול המכיל המוגדרים על ידי המשתמש Transform קוד.

בואו לראות דוגמה המוגדרים על ידי המשתמש Transform הקוד שלהלן (עבור מבוא TensorFlow Transform APIs, ראה הדרכה ). ראשית, אנו מגדירים כמה קבועים עבור הנדסת תכונות:

הערה: %%writefile קסם תא יחסוך את תוכן התא בתור .py קובץ בדיסק. זה מאפשר Transform רכיב לטעון את הקוד שלך כמודול.

קחו הצצה אל transform_graph חפץ. זה מצביע על ספרייה המכילה שלוש ספריות משנה.

train_uri = transform.outputs['transform_graph'].get()[0].uri
os.listdir(train_uri)

['transform_fn', 'transformed_metadata', 'metadata']

transformed_metadata בתיקייה מכילה סכימת נתון המעובדים. transform_fn בתיקייה מכילה הגרף המקדים בפועל. metadata בתיקייה מכילה בסכימה של נתון המקוריים.

אנו יכולים גם להסתכל על שלוש הדוגמאות הראשונות שעברו טרנספורמציה:

# Get the URI of the output artifact representing the transformed examples, which is a directory
train_uri = os.path.join(transform.outputs['transformed_examples'].get()[0].uri, 'Split-train')

# Get the list of files in this directory (all compressed TFRecord files)
tfrecord_filenames = [os.path.join(train_uri, name)
                      for name in os.listdir(train_uri)]

# Create a `TFRecordDataset` to read these files
dataset = tf.data.TFRecordDataset(tfrecord_filenames, compression_type="GZIP")

# Iterate over the first 3 records and decode them.
for tfrecord in dataset.take(3):
  serialized_example = tfrecord.numpy()
  example = tf.train.Example()

Evaluator רכיב מחשב מדדי ביצועי מודל על סט ההערכה. היא משתמשת ניתוח דגם TensorFlow הספרייה. Evaluator גם יכול לאמת אופציונלי כי מודל מודרך חדש הוא טוב יותר מאשר הדגם הקודם. זה שימושי בהגדרת צינור ייצור שבה אתה יכול לאמן ולאמת מודל אוטומטית מדי יום. במחברת זו, אנו רק לאמן את מודל אחד, כך Evaluator אוטומטי יתייג את מודל "טוב".

Evaluator ייקח כקלט את נתון ExampleGen , המודל המאומן מן Trainer , ותצורת חיתוך. תצורת החיתוך מאפשרת לך לחתוך את המדדים שלך על ערכי תכונה (למשל איך המודל שלך מתפקד בנסיעות במונית שמתחילות ב-8 בבוקר לעומת 20:00?). ראה דוגמה של תצורה זו להלן:

            # model.compile(..., metrics=[...]), etc) will be computed
            # automatically.

            # add them keyed by metric name to the thresholds map.

באמצעות evaluation הפלט נוכל להראות את להדמית ברירת המחדל של מדדים הגלובליים על סט ההערכה כול.

context.show(evaluator.outputs['evaluation'])

כדי לראות את ההדמיה עבור מדדי הערכה פרוסים, אנו יכולים להתקשר ישירות לספריית ניתוח המודלים של TensorFlow.

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)

# Show data sliced along feature column trip_start_hour.
tfma.view.render_slicing_metrics(
    tfma_result, slicing_column='trip_start_hour')

SlicingMetricsViewer(config={'weightedExamplesColumn': 'example_count'}, data=[{'slice': 'trip_start_hour:19',…

הדמיה זו מציגה אותם מדדים, אבל מחושב בכל ערך התכונה של trip_start_hour במקום על הסט הערכה כולה.

ניתוח מודלים של TensorFlow תומך בהדמיות רבות אחרות, כגון אינדיקטורים של הוגנות ושרטוט סדרת זמן של ביצועי מודל. כדי ללמוד עוד, ראה את המדריך .

מכיוון שהוספנו ספים לתצורה שלנו, פלט אימות זמין גם. Precence של blessing חפצה מציין כי המודל שלנו עבר אימות. מכיוון שזהו האימות הראשון שמתבצע המועמד מתברך אוטומטית.

blessing_uri = evaluator.outputs['blessing'].get()[0].uri
!ls -l {blessing_uri}

total 0
-rw-rw-r-- 1 kbuilder kbuilder 0 Dec  5 11:03 BLESSED

כעת ניתן גם לאמת את ההצלחה על ידי טעינת רשומת תוצאת האימות:

PATH_TO_RESULT = evaluator.outputs['evaluation'].get()[0].uri
print(tfma.load_validation_result(PATH_TO_RESULT))

validation_ok: true
validation_details {
  slicing_details {
    slicing_spec {
    }
    num_matching_slices: 25
  }

במיוחד, ה-Pusher ייצא את הדגם שלך בפורמט SavedModel, שנראה כך:

push_uri = pusher.outputs['pushed_model'].get()[0].uri
model = tf.saved_model.load(push_uri)

for item in model.signatures.items():
  pp.pprint(item)
