Web24 Mar 2024 · Hi, In TF 2.1, I would advise you to write your custom learning rate scheduler as a tf.keras.optimizers.schedules.LearningRateSchedule instance and pass it as learning_rate argument to your model's optimizer - this way you do not have to worry about it further.. In TF 2.2 (currently in RC1), this issue will be fixed by implementing a … WebLearning rate scheduler. At the beginning of every epoch, this callback gets the updated learning rate value from schedule function provided at __init__, with the current epoch and current learning rate, and applies the updated learning rate on the optimizer.. Arguments. schedule: a function that takes an epoch index (integer, indexed from 0) and current …
