জুপিটার/কোলাব পরিবেশে এমএলএমডি এবং টিএফএক্স পাইপলাইন সহ মডেল কার্ড টুলকিট ব্যবহার করে কীভাবে একটি মডেল কার্ড তৈরি করা যায় এই নোটবুকটি দেখায়। আপনি মডেল কার্ড সম্পর্কে আরও জানতে পারেন https://modelcards.withgoogle.com/about
সেটআপ
আমাদের প্রথমে ক) প্রয়োজনীয় প্যাকেজগুলি ইনস্টল এবং আমদানি করতে হবে এবং খ) ডেটা ডাউনলোড করতে হবে।
পিপ 20.2 এ আপগ্রেড করুন এবং TFX ইনস্টল করুন
pip install -q --upgrade pip==20.2
pip install -q "tfx==0.26.0"
pip install -q model-card-toolkit
আপনি কি রানটাইম রিস্টার্ট করেছেন?
আপনি যদি Google Colab ব্যবহার করেন, প্রথমবার উপরের সেলটি চালানোর সময়, আপনাকে অবশ্যই রানটাইমটি পুনরায় চালু করতে হবে (রানটাইম > রানটাইম পুনরায় চালু করুন ...)। Colab যেভাবে প্যাকেজগুলি লোড করে তার কারণেই এটি হয়েছে৷
প্যাকেজ আমদানি করুন
আমরা স্ট্যান্ডার্ড TFX কম্পোনেন্ট ক্লাস সহ প্রয়োজনীয় প্যাকেজ আমদানি করি এবং লাইব্রেরি সংস্করণ পরীক্ষা করি।

'positive rate seems quite low. This is true to an even greater degree '
'when we only look at the “female” sub-group, because there are even '
'fewer female examples in the $50,000+ earner group, causing our model to '
'overfit these examples. To avoid this, we can try various remediation '
