WebMar 6, 2024 · This corresponds to increasing the learning rate linearly for the first ``warmup_steps`` training steps, and decreasing it thereafter proportionally to the inverse square root of the step number. Args: optimizer (Optimizer): Wrapped optimizer. warmup_steps (int): The number of steps to linearly increase the learning rate. Weblr_lambda ( function or list) – A function which computes a multiplicative factor given an integer parameter epoch, or a list of such functions, one for each group in optimizer.param_groups. last_epoch ( int) – The index of last epoch. Default: -1. verbose ( bool) – If True, prints a message to stdout for each update. ku yakin kau hadir di sini lirik
