नोटबुक डाउनलोड करेंइस नोटबुक-आधारित ट्यूटोरियल में, हम एक TFX पाइपलाइन बनाएंगे और चलाएंगे जो एक सरल वर्गीकरण मॉडल बनाती है और कई रनों में इसके प्रदर्शन का विश्लेषण करती है। इस नोटबुक TFX पाइपलाइन हम में बनाया पर आधारित है सरल TFX पाइपलाइन ट्यूटोरियल । यदि आपने अभी तक उस ट्यूटोरियल को नहीं पढ़ा है, तो इस नोटबुक के साथ आगे बढ़ने से पहले आपको इसे पढ़ना चाहिए।
जैसे ही आप अपने मॉडल में बदलाव करते हैं या इसे नए डेटासेट के साथ प्रशिक्षित करते हैं, आपको यह जांचना होगा कि आपका मॉडल बेहतर हुआ है या खराब हो गया है। सटीकता जैसे शीर्ष-स्तरीय मीट्रिक की जाँच करना ही पर्याप्त नहीं हो सकता है। प्रत्येक प्रशिक्षित मॉडल को उत्पादन में धकेलने से पहले उसका मूल्यांकन किया जाना चाहिए।
हम एक जोड़ देगा Evaluator पिछले ट्यूटोरियल में बनाया पाइप लाइन के लिए घटक। मूल्यांकनकर्ता घटक आपके मॉडलों के लिए गहन विश्लेषण करता है और नए मॉडल की तुलना आधार रेखा से यह निर्धारित करने के लिए करता है कि वे "काफी अच्छे" हैं। यह का उपयोग कर कार्यान्वित किया जाता है TensorFlow मॉडल विश्लेषण पुस्तकालय।
कृपया देखें TFX पाइपलाइन को समझना TFX में विभिन्न अवधारणाओं के बारे में अधिक जानने के लिए।
सेट अप
सेटअप प्रक्रिया पिछले ट्यूटोरियल की तरह ही है।
हमें सबसे पहले टीएफएक्स पायथन पैकेज को स्थापित करना होगा और डेटासेट डाउनलोड करना होगा जिसका उपयोग हम अपने मॉडल के लिए करेंगे।
पिप अपग्रेड करें
स्थानीय रूप से चलते समय सिस्टम में पिप को अपग्रेड करने से बचने के लिए, यह सुनिश्चित करने के लिए जांचें कि हम कोलाब में चल रहे हैं। स्थानीय प्रणालियों को निश्चित रूप से अलग से अपग्रेड किया जा सकता है।
try:
import colab
!pip install --upgrade pip
except:
pass
टीएफएक्स स्थापित करें
pip install -U tfx
क्या आपने रनटाइम को पुनरारंभ किया?
यदि आप Google Colab का उपयोग कर रहे हैं, जब आप पहली बार ऊपर सेल चलाते हैं, तो आपको "रनटाइम को पुनरारंभ करें" बटन पर क्लिक करके या "रनटाइम> रनटाइम पुनरारंभ करें ..." मेनू का उपयोग करके रनटाइम को पुनरारंभ करना होगा। ऐसा इसलिए है क्योंकि Colab संकुल को लोड करता है।
TensorFlow और TFX संस्करणों की जाँच करें।

print('TensorFlow version: {}'.format(tf.__version__))

print('TFX version: {}'.format(tfx.__version__))

चर सेट करें
पाइपलाइन को परिभाषित करने के लिए कुछ चर का उपयोग किया जाता है। आप इन चरों को अपनी इच्छानुसार अनुकूलित कर सकते हैं। डिफ़ॉल्ट रूप से पाइपलाइन से सभी आउटपुट वर्तमान निर्देशिका के तहत उत्पन्न होंगे।

PIPELINE_NAME = "penguin-tfma"
# 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.
उदाहरण डेटा तैयार करें
हम एक ही उपयोग करेगा पामर पेंगुइन डाटासेट ।
इस डेटासेट में चार संख्यात्मक विशेषताएं हैं जिन्हें पहले से ही [0,1] श्रेणी के लिए सामान्यीकृत किया गया था। हम एक वर्गीकरण मॉडल जो भविष्यवाणी का निर्माण करेगा species पेंगुइन की।
क्योंकि TFXexampleGen एक निर्देशिका से इनपुट पढ़ता है, हमें एक निर्देशिका बनाने और उसमें डेटासेट कॉपी करने की आवश्यकता है।
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-datal5lxy_yw/data.csv', <http.client.HTTPMessage at 0x7fa18a9da150>)
एक पाइपलाइन बनाएं
हम एक जोड़ देगा Evaluator पाइपलाइन हम में बनाया करने के लिए घटक सरल TFX पाइपलाइन ट्यूटोरियल ।
एक मूल्यांकनकर्ता घटक एक से इनपुट डेटा की आवश्यकता है ExampleGen घटक और एक से एक मॉडल Trainer घटक और एक tfma.EvalConfig वस्तु। हम वैकल्पिक रूप से एक बेसलाइन मॉडल की आपूर्ति कर सकते हैं जिसका उपयोग नए प्रशिक्षित मॉडल के साथ मेट्रिक्स की तुलना करने के लिए किया जा सकता है।
एक मूल्यांकनकर्ता उत्पादन कलाकृतियों, के दो प्रकार बनाता है ModelEvaluation और ModelBlessing । मॉडल मूल्यांकन में विस्तृत मूल्यांकन परिणाम होता है जिसे टीएफएमए पुस्तकालय के साथ आगे जांचा और देखा जा सकता है। ModelBlessing में एक बूलियन परिणाम होता है कि क्या मॉडल दिए गए मानदंडों को पारित करता है और बाद के घटकों जैसे पुशर में सिग्नल के रूप में उपयोग किया जा सकता है।
मॉडल प्रशिक्षण कोड लिखें
हम में के रूप में एक ही मॉडल कोड का उपयोग करेगा सरल TFX पाइपलाइन ट्यूटोरियल ।

हम मूल्यांकनकर्ता के माध्यम से करने के लिए निम्न जानकारी देने की आवश्यकता eval_config :
- कॉन्फ़िगर करने के लिए अतिरिक्त मीट्रिक (यदि मॉडल में परिभाषित से अधिक मीट्रिक चाहते हैं)।
- कॉन्फ़िगर करने के लिए स्लाइस
- सत्यापन को शामिल करने के लिए सत्यापित करने के लिए मॉडल सत्यापन थ्रेसहोल्ड
क्योंकि SparseCategoricalAccuracy पहले से ही शामिल किया गया था model.compile() कॉल, यह विश्लेषण में स्वचालित रूप से शामिल किया जाएगा। इसलिए हम यहां कोई अतिरिक्त मीट्रिक नहीं जोड़ते हैं। SparseCategoricalAccuracy तय करने के लिए मॉडल काफी अच्छा है, भी है इस्तेमाल किया जाएगा।
हम संपूर्ण डेटासेट और प्रत्येक पेंगुइन प्रजाति के लिए मीट्रिक की गणना करते हैं। SlicingSpec निर्दिष्ट करता है कि हम कैसे घोषित मैट्रिक्स दिखाते हैं।
दो थ्रेसहोल्ड हैं जिन्हें एक नया मॉडल पास करना चाहिए, एक 0.6 की पूर्ण सीमा है और दूसरा एक सापेक्ष सीमा है कि यह बेसलाइन मॉडल से अधिक होना चाहिए। जब आप पहली बार के लिए पाइप लाइन चलाने के लिए, change_threshold नजरअंदाज कर दिया जाएगा और केवल value_threshold जाँच की जाएगी। आप पाइप लाइन एक बार से अधिक चलाते हैं, Resolver पिछले रन से एक मॉडल मिल जाएगा और यह तुलना के लिए एक आधार रेखा मॉडल के रूप में इस्तेमाल किया जाएगा।

जब पाइपलाइन पूरी हो जाती है, तो आपको निम्न जैसा कुछ देखने में सक्षम होना चाहिए:
INFO:absl:Blessing result True written to pipelines/penguin-tfma/Evaluator/blessing/4.
या आप मैन्युअल रूप से आउटपुट निर्देशिका की जांच भी कर सकते हैं जहां उत्पन्न कलाकृतियों को संग्रहीत किया जाता है। आप जाएँ pipelines/penguin-tfma/Evaluator/blessing/ एक फ़ाइल broswer के साथ, आप एक नाम के साथ एक फ़ाइल देख सकते हैं BLESSED या NOT_BLESSED मूल्यांकन परिणाम के अनुसार।
तो आशीर्वाद परिणाम है False , पुशर को मॉडल पुश करने के लिए मना कर देगा serving_model_dir , क्योंकि मॉडल काफी अच्छा उत्पादन में प्रयोग की जाने वाली नहीं है।
आप संभवतः विभिन्न मूल्यांकन विन्यासों के साथ पाइपलाइन को फिर से चला सकते हैं। यहां तक कि अगर आप ठीक उसी config और डेटासेट के साथ पाइप लाइन चलाने के लिए, प्रशिक्षित मॉडल थोड़ा मॉडल प्रशिक्षण जो एक को जन्म दे सकता के निहित अनियमितता की वजह से अलग हो सकता है NOT_BLESSED मॉडल।
पाइपलाइन के आउटपुट की जांच करें
आप ModelEvaluation आर्टिफैक्ट में मूल्यांकन परिणाम की जांच और कल्पना करने के लिए TFMA का उपयोग कर सकते हैं।
आउटपुट कलाकृतियों से विश्लेषण परिणाम प्राप्त करें
इन आउटपुट को प्रोग्रामेटिक रूप से ढूंढने के लिए आप एमएलएमडी एपीआई का उपयोग कर सकते हैं। सबसे पहले, हम कुछ उपयोगिता कार्यों को परिभाषित करेंगे जो कि अभी उत्पादित आउटपुट कलाकृतियों की खोज के लिए हैं।

return execution_lib.get_artifacts_dict(metadata, latest_execution.id,

हम के नवीनतम निष्पादन पा सकते हैं Evaluator घटक है और इसका उत्पादन कलाकृतियों मिलता है।

Evaluator हमेशा एक मूल्यांकन विरूपण साक्ष्य देता है, और हम TensorFlow मॉडल विश्लेषण लाइब्रेरी का उपयोग कर यह कल्पना कर सकते हैं। उदाहरण के लिए, निम्नलिखित कोड प्रत्येक पेंगुइन प्रजाति के लिए सटीकता मीट्रिक प्रस्तुत करेगा।
import tensorflow_model_analysis as tfma
eval_result = tfma.load_eval_result(eval_artifact.uri)
tfma.view.render_slicing_metrics(eval_result, slicing_column='species')
SlicingMetricsViewer(config={'weightedExamplesColumn': 'example_count'}, data=[{'slice': 'species:0', 'metrics…
आप में 'sparse_categorical_accuracy' चुनते हैं, Show ड्रॉप-डाउन सूची, तुम प्रजातियों प्रति सटीकता मान देख सकते हैं। हो सकता है कि आप और स्लाइस जोड़ना चाहें और जांच लें कि क्या आपका मॉडल सभी वितरण के लिए अच्छा है और यदि कोई संभावित पूर्वाग्रह है।
