How to replace feature extraction network?

[284513016]

Hello, I would like to quote your RecurrentCriss-CrossAttention separately, but the main framework has CNN feature extraction, so the CNN feature extraction and segmentation module is no longer needed, but I do not know how to get independent RecurrentCriss-CrossAttention code, I hope to get your guidance.Thank you very much

The independent RCCA code？ The RCCA class is defined here.

Thank you very much for your reply
For the complete ccnet, I do not want CNN feature extraction and the last segmention two modules, what should I do?Can we reduce cc and rcca?That is, the part from X to H "in ccnet paper

Yes，you can modify the RCCA module and remove the segmentation layers.

Build.py file can not be compiled under the windows system how to solve?

This repo doesn't support Windows system.

What are the functions of the following modules in CC?
Bottleneck(nn.Module)
class PSPModule(nn.Module)
def _make_layer(self, block, planes, blocks, stride=1, dilation=1, multi_grid=1)
Do you want to extract rcca module above?

[speedinghzl]

I don't know exactly what you mean.
