你好,我想请问一下具体是在多少个epoch后做finetune的呢,finetune的学习率和步长具体是多少呢?

我在640 * 640的输入上做训练,使用lr_step为90、120,lr为5e-4,batch_size为8。之后将140的epoch取出,送入第二步做finetune,输入尺寸为800 * 800,使用lr_step为30、60,lr为5e-4,batch_size为8。

训练结果为

1.First train with the size of 640×640/514×514

2.Then fine tune with the size of 800×800

3.For the easy and hard part, s = s * np.random. Choice (np.arange(0.3, 1.2, 0.1)). The larger the value, the more small samples will be generated
