পেঙ্গুইন ডেটাসেট ব্যবহার করে সাধারণ টিএফএক্স পাইপলাইন টিউটোরিয়াল

একটি সাধারণ TFX পাইপলাইন চালানোর জন্য একটি ছোট টিউটোরিয়াল।

এই নোটবুক-ভিত্তিক টিউটোরিয়ালে, আমরা একটি সাধারণ শ্রেণিবিন্যাস মডেলের জন্য একটি TFX পাইপলাইন তৈরি করব এবং চালাব। পাইপলাইনে তিনটি প্রয়োজনীয় TFX উপাদান থাকবে: ExampleGen, Trainer এবং Pusher। পাইপলাইনে সবচেয়ে ন্যূনতম এমএল ওয়ার্কফ্লো রয়েছে যেমন ডেটা আমদানি করা, একটি মডেলকে প্রশিক্ষণ দেওয়া এবং প্রশিক্ষিত মডেল রপ্তানি করা।

দয়া করে দেখুন TFX পাইপলাইন বুঝুন TFX বিভিন্ন ধারণা সম্পর্কে আরো জানতে।

সেট আপ করুন

আমাদের প্রথমে TFX পাইথন প্যাকেজ ইনস্টল করতে হবে এবং ডেটাসেটটি ডাউনলোড করতে হবে যা আমরা আমাদের মডেলের জন্য ব্যবহার করব।

পিপ আপগ্রেড করুন

স্থানীয়ভাবে চালানোর সময় একটি সিস্টেমে পিপ আপগ্রেড করা এড়াতে, আমরা Colab-এ চালাচ্ছি কিনা তা নিশ্চিত করুন। স্থানীয় সিস্টেম অবশ্যই আলাদাভাবে আপগ্রেড করা যেতে পারে।

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

TFX ইনস্টল করুন

pip install -U tfx

আপনি কি রানটাইম রিস্টার্ট করেছেন?

আপনি যদি Google Colab ব্যবহার করেন, প্রথমবার যখন আপনি উপরের সেলটি চালান, তাহলে আপনাকে অবশ্যই উপরে "রিস্টার্ট RUNTIME" বোতামে ক্লিক করে বা "রানটাইম > রানটাইম রিস্টার্ট..." মেনু ব্যবহার করে রানটাইম রিস্টার্ট করতে হবে। Colab যেভাবে প্যাকেজগুলি লোড করে তার কারণেই এটি হয়েছে৷

TensorFlow এবং TFX সংস্করণ পরীক্ষা করুন।

ভেরিয়েবল সেট আপ করুন

একটি পাইপলাইন সংজ্ঞায়িত করতে ব্যবহৃত কিছু ভেরিয়েবল আছে। আপনি আপনার ইচ্ছা মত এই ভেরিয়েবল কাস্টমাইজ করতে পারেন. ডিফল্টরূপে পাইপলাইন থেকে সমস্ত আউটপুট বর্তমান ডিরেক্টরির অধীনে তৈরি করা হবে।

উদাহরণ ডেটা প্রস্তুত করুন

আমরা আমাদের TFX পাইপলাইনে ব্যবহারের জন্য উদাহরণ ডেটাসেট ডাউনলোড করব। ডেটা সেটটি আমরা ব্যবহার করা হয় পামার পেঙ্গুইনদের ডেটা সেটটি যা অন্যান্য ব্যবহার করা হয় TFX উদাহরণ

এই ডেটাসেটে চারটি সংখ্যাসূচক বৈশিষ্ট্য রয়েছে:

  • culmen_length_mm
  • culmen_depth_mm
  • ফ্লিপার_দৈর্ঘ্য_মিমি
  • বডি_মাস_জি

সমস্ত বৈশিষ্ট্য ইতিমধ্যে পরিসীমা [0,1] থাকার জন্য স্বাভাবিক করা হয়েছে। আমরা একটি শ্রেণীবিভাগ মডেল যা অনুমান গড়ে তুলবে species পেঙ্গুইনদের করুন।

যেহেতু TFX ExampleGen একটি ডিরেক্টরি থেকে ইনপুট পড়ে, আমাদের একটি ডিরেক্টরি তৈরি করতে হবে এবং এতে ডেটাসেট কপি করতে হবে।

একটি পাইপলাইন তৈরি করুন

TFX পাইপলাইনগুলি Python API ব্যবহার করে সংজ্ঞায়িত করা হয়। আমরা একটি পাইপলাইন সংজ্ঞায়িত করব যা নিম্নলিখিত তিনটি উপাদান নিয়ে গঠিত।

  • CsvExampleGen: ডেটা ফাইলগুলিতে পড়ে এবং পরবর্তী প্রক্রিয়াকরণের জন্য সেগুলিকে TFX অভ্যন্তরীণ বিন্যাসে রূপান্তর করে। সেখানে একাধিক হয় ExampleGen বিভিন্ন ফরম্যাটের জন্য গুলি। এই টিউটোরিয়ালে, আমরা CsvExampleGen ব্যবহার করব যা CSV ফাইল ইনপুট নেয়।
  • প্রশিক্ষক: একটি এমএল মডেলকে প্রশিক্ষণ দেয়। প্রশিক্ষক উপাদান ব্যবহারকারীদের কাছ থেকে একটি মডেল সংজ্ঞা কোড প্রয়োজন। আপনি একটি মডেল প্রশিক্ষণ এবং _saved মডেল ফরম্যাটে সেভ করুন কিভাবে নির্দিষ্ট করতে TensorFlow API গুলি ব্যবহার করতে পারেন।
  • পুশার: TFX পাইপলাইনের বাইরে প্রশিক্ষিত মডেলটি কপি করে। বিমানপোত উপাদান প্রশিক্ষিত এমএল মডেলের একটি স্থাপনার প্রক্রিয়া ভাবা যেতে পারে।

আসলে পাইপলাইন সংজ্ঞায়িত করার আগে, আমাদের প্রথমে প্রশিক্ষক উপাদানের জন্য একটি মডেল কোড লিখতে হবে।

মডেল প্রশিক্ষণ কোড লিখুন

আমরা TensorFlow Keras API ব্যবহার করে শ্রেণিবিন্যাসের জন্য একটি সাধারণ DNN মডেল তৈরি করব। এই মডেল প্রশিক্ষণ কোড একটি পৃথক ফাইল সংরক্ষণ করা হবে.

এই টিউটোরিয়ালে আমরা ব্যবহার করবে জেনেরিক প্রশিক্ষক TFX যা Keras ভিত্তিক মডেল সমর্থন করে। আপনি সম্বলিত একটি পাইথন ফাইলটি লিখতে প্রয়োজন run_fn ফাংশন, যার জন্য entrypoint হয় Trainer অংশ।
