请问如何修改学习率衰减器

1

您代码中的学习率衰减器为 CFG.TRAIN.LR_SCHEDULER.TYPE = "MultiStepLR" CFG.TRAIN.LR_SCHEDULER.PARAM = { "milestones": [30, 40, 45], "gamma": 0.1 } 请问如何更改成 torch.optim.lr_scheduler.ReduceLROnPlateau(optimizer, mode='min', factor=0.1, patience=10, verbose=False, threshold=0.001, threshold_mode='rel', cooldown=0, min_lr=2e-6, eps=1e-08)这种 或者别的学习率衰减器
