Optimwrapper

WebOptimizer wrapper provides a unified interface for single precision training and automatic mixed precision training with different hardware. OptimWrapper encapsulates optimizer to provide simplified interfaces for commonly used training techniques such as gradient accumulative and grad clips. WebWe use the optim_wrapperfield to configure the strategies of optimization, which includes choices of the optimizer, parameter-wise configurations, gradient clipping and accumulation. A simple example can be: optim_wrapper=dict(type='OptimWrapper',optimizer=dict(type='SGD',lr=0.0003,weight_decay=0.0001))
