Question: Why the multi frame feature was not used? Typo?

Hi, In the networks.py, multi_feat is not used at all? Thank you so much! Should I change that to oth_feat=torch.cat([self.comb_back(torch.cat([img_feat,back_feat],dim=1)),self.comb_seg(torch.cat([img_feat,seg_feat],dim=1)),self.comb_multi(torch.cat([img_feat,multi_feat],dim=1))],dim=1)

def forward(self, image,back,seg,multi):
		img_feat1=self.model_enc1(image)
		img_feat=self.model_enc2(img_feat1)

		back_feat=self.model_enc_back(back)
		seg_feat=self.model_enc_seg(seg)
		multi_feat=self.model_enc_multi(multi)

oth_feat=torch.cat([self.comb_back(torch.cat([img_feat,back_feat],dim=1)),self.comb_seg(torch.cat([img_feat,seg_feat],dim=1)),self.comb_multi(torch.cat([img_feat,back_feat],dim=1))],dim=1)

		out_dec=self.model_res_dec(torch.cat([img_feat,oth_feat],dim=1))

		out_dec_al=self.model_res_dec_al(out_dec)
		al_out=self.model_al_out(out_dec_al)

		out_dec_fg=self.model_res_dec_fg(out_dec)
		out_dec_fg1=self.model_dec_fg1(out_dec_fg)
		fg_out=self.model_fg_out(torch.cat([out_dec_fg1,img_feat1],dim=1))
