TensorBoard হল TensorFlow-এ পরিমাপ এবং ভিজ্যুয়ালাইজেশন প্রদানের জন্য একটি অন্তর্নির্মিত টুল। সাধারণ মেশিন লার্নিং এক্সপেরিমেন্ট মেট্রিক্স, যেমন নির্ভুলতা এবং ক্ষতি, টেনসরবোর্ডে ট্র্যাক এবং প্রদর্শিত হতে পারে। TensorBoard TensorFlow 1 এবং 2 কোডের সাথে সামঞ্জস্যপূর্ণ।
TensorFlow 1-এ, tf.estimator.Estimator
ডিফল্টরূপে টেনসরবোর্ডের সারাংশ সংরক্ষণ করে। তুলনায়, TensorFlow 2-এ, tf.keras.callbacks.TensorBoard
কলব্যাক ব্যবহার করে সারাংশ সংরক্ষণ করা যেতে পারে।
এই নির্দেশিকাটি দেখায় কিভাবে TensorBoard ব্যবহার করতে হয়, প্রথমে, টেনসরফ্লো 1 এ এস্টিমেটর সহ, এবং তারপর, কিভাবে TensorFlow 2-এ সমতুল্য প্রক্রিয়া চালাতে হয়।
