您好,关于optimizer的设置,您这边设置了 'img_backbone': dict(lr_mult=0.1),请问这个有什么特殊的说法吗?
optimizer = dict( type='AdamW', lr=2e-4, paramwise_cfg=dict( custom_keys={ 'img_backbone': dict(lr_mult=0.1), }), weight_decay=0.01)
在img_backbone这边,为什么选择frozen_stages=1呢? img_backbone=dict( type='ResNet', depth=101, num_stages=4, out_indices=(1,2,3), frozen_stages=1, norm_cfg=dict(type='BN2d', requires_grad=False), norm_eval=True, style='caffe', #with_cp=True, # using checkpoint to save GPU memory dcn=dict(type='DCNv2', deform_groups=1, fallback_on_stride=False), # original DCNv2 will print log when perform load_state_dict stage_with_dcn=(False, False, True, True)),
非常感谢您的阅读,期待能够尽快得到您会回复~

同学你好,这块是直接参考bevformer里的超参的,没有改过这个参数
