原创 【mmcv、mmdetection、mmaction】训练深度学习模型时如何自定义优化器“optimizer”，为模型不同layer设置不同的学习率
mmaction, mmdetection的代码库使用mmcv代码构建了深度学习训练框架，其中主要的类是’runner’ 。model和optimizer都是runner的成员。默认configs下，optimizer通过传入字典参数optimizer = dict(type=‘SGD’, lr=0.1, momentum=0.9, weight_decay=0.0005)进行初始化。此时，整个模型的学习率都是0.1，不可对复杂模型的特定层或者参数设定不同的学习率lr。本文展示了如何解决这一问题：
