TensorBoard هي أداة مضمنة لتوفير القياسات والتصورات في TensorFlow. يمكن تتبع مقاييس تجربة التعلم الآلي الشائعة ، مثل الدقة والفقد ، وعرضها في TensorBoard. TensorBoard متوافق مع كود TensorFlow 1 و 2.

في TensorFlow 1 ، يحفظ tf.estimator.Estimator الملخصات لـ TensorBoard افتراضيًا. بالمقارنة ، في TensorFlow 2 ، يمكن حفظ الملخصات باستخدام رد tf.keras.callbacks.TensorBoard .

يوضح هذا الدليل كيفية استخدام TensorBoard ، أولاً ، في TensorFlow 1 مع المقدرون ، ثم كيفية تنفيذ العملية المكافئة في TensorFlow 2.
