Training takes a long time, and it is always sad to lose progress because your program crashes. So Stable-Baselines3 offers some nice callbacks to save your progress over time. I recommend usingEvalCallbackandCheckpointCallback. from stable_baselines3.common.callbacks import EvalCallback, Checkpoin...
除此之外,我们还加入了tensorboard_log参数,欸嘿,没错,stable_baselines3封装了使用tensorboard高颜值前端服务器可视化的接口,不熟悉tensorboard的同学可以参考我曾经的Deep Learning可视化工具合集文章: 然后我们稍微加大一下训练的采样数(时间步的数量): model.learn(total_timesteps=1e6) OK,继续训练,在1600s后,训练完...

IPDM decreases less than baselines. Full size image Implementation details For different pre-trained language models (PLMs), we use AdamW as the optimizer. The learning rates are searched in \(a \times 10^{-b}\), where \(a=1\) or 5 and b is an integer from 1 to 7, to find the...
