FaPN issues

the output channals of FeatureAlign_V2

2

`self.dcpack_L2 = dcn_v2(out_nc, out_nc, 3, stride=1, padding=1, dilation=1, deformable_groups=8, extra_offset_mask=True)` why out_nc is 256, not 216(3 x kernel_size x kernal_size x deformable_groups) ?

单独的FSM和FAM模块

您好，看了您的论文，希望借助一下您论文中的FSM和FAM模块，直接插入到我的网络中，但我没有找到这两个模块的单独实现，请问这两个模块的单独实现在哪里呢，谢谢

Codes about FeatureAlign_V2

In module[ FeatureAlign_v2](https://github.com/EMI-Group/FaPN/blob/main/detectron2/modeling/backbone/fan.py) `offset = self.offset(torch.cat([feat_arm, feat_up * 2], dim=1)) # concat for offset by compute the dif` Why multiple feat_up by 2?
