WebReturn last computed learning rate by current scheduler. get_lr() [source] Calculates the learning rate at batch index. This function treats self.last_epoch as the last batch index. If self.cycle_momentum is True, this function has a side effect of updating the optimizer’s momentum. print_lr(is_verbose, group, lr, epoch=None) WebNov 21, 2024 · ptrblck November 21, 2024, 8:26pm 2. Yes, you won’t need a val folder, as you are selecting one sample as the test case for LOOCV. There are still some issues in your code: Currently train_model takes the DataLoader and iterates it (line79). However, you are also iterating your DataLoader in line 230.
