Describe

解决了issue：#40321
增加了CyclicLR优化调度器。具体地，paddle.optimizer.lr.CyclicLR(base_learning_rate,max_learning_rate,step_size_up,step_size_down, mode='triangular',gamma=1.,scale_fn=None,scale_mode='cycle',last_epoch=-1,verbose=False)能控制学习率以固定周期在base_learning_rate和max_learning_rate之间变化，它的调整是以batch step进行的，同时还有3种内置的波幅调整策略：“triangular”、“triangular2”、“exp_range”。
设计文档：PaddlePaddle/community#33
中文文档：PaddlePaddle/docs#4315

PR-CI-Coverage表示代码覆盖率不够

dingjiaweiww · 2022-04-02T02:42:31Z

R-CI-iScan-Python指代码不符合规范
