的新的学习率, i n i t i a l _ l r initial\_lr initial_lr是初始的学习率, s t e p _ s i z e step\_size step_size是参数step_size,γ \gamma γ是参数gamma。 参数: optimizer (Optimizer):要更改学习率的优化器; step_size(int):每训练step_size个epoch,更新一次参数; gamma(...
3. last_epoch (int):最后一个epoch的index,如果是训练了很多个epoch后中断了,继续训练,这个值就等于加载的模型的epoch。默认为-1表示从头开始训练,即从epoch=1开始。 注意: 在将optimizer传给scheduler后,在shcduler类的__init__方法中会给optimizer.param_groups列表中的那个元素(字典)增加一个key = "initial...
torch.optim.lr_scheduler.ExponentialLR(optimizer, gamma, last_epoch=-1, verbose=False) 描述:按指数衰减调整学习率,调整公式:lr = lr*gamma**epoch。 参数: gamma (float):学习率调整倍数。 last_epoch (int):上一个epoch数,这个变量用于指示学习率是否需要调整。当last_epoch符合设定的间隔时就会调整学习...

Alternatively, knockout of endogenous LRRK2 clearly blunted the HPA response and this could stem from reduced kinase activity, as well as potential reductions in protein signaling pathways, most notably, p38, JNK, interferon gamma, as well as a number of RAB proteins that control vesicular ...
