有个疑问, 当多节点训练时,学习率退火中的num_samples_processed是一个节点的处理的样本数还是所有节点处理的样本数之和?

您好,欢迎关注PaddlePaddle!
多节点训练时,paddle在参数优化时,主要有两种方式:
第一种方式目前应该只有momentum是这样,支持learning_rate decay的参数优化方式目前都是本地计算diff发送。所以num_samples_processed是一个节点的。
num_samples_processed
参考:
#2347
https://github.com/PaddlePaddle/Paddle/blob/develop/paddle/trainer/RemoteParameterUpdater.cpp#L204
Sorry, something went wrong.
由于此issue长时间没有更新,所以先关掉了,如有问题欢迎随时打开。
