WebNov 30, 2024 · Task Scheduler. The Task Scheduler is a tool included with Windows that allows predefined actions to be automatically executed whenever a certain set of … 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.
WebNotice that such decay can happen simultaneously with other changes to the learning rate from outside this scheduler. When last_epoch=-1, sets initial lr as lr. Args: optimizer (Optimizer): Wrapped optimizer. step_size (int): Period of learning rate decay. gamma (float): Multiplicative factor of learning rate decay. WebJun 25, 2024 · This should work: torch.save (net.state_dict (), dir_checkpoint + f'/CP_epoch {epoch + 1}.pth') The current checkpoint should be stored in the current working directory using the dir_checkpoint as part of its name. PS: You can post code by wrapping it into three backticks ```, which would make debugging easier.
