Hey, I've met the same problem. Did you solve it?

Hey, I've met the same problem. Did you solve it?

It seems the input dimensional dismatch of the call function of class nn.CosineEmbeddingLoss().

In the file trains/singleTask/DMD.py, replace the code

cosine_similarity_s_c_l = self.cosine(output['s_l'], output['c_l'], torch.tensor([-1]).cuda()).mean(0)
cosine_similarity_s_c_v = self.cosine(output['s_v'], output['c_v'], torch.tensor([-1]).cuda()).mean(0)
cosine_similarity_s_c_a = self.cosine(output['s_a'], output['c_a'], torch.tensor([-1]).cuda()).mean(0)

with

cosine_similarity_s_c_l = self.cosine(output['s_l'].reshape(-1, 50), output['c_l'].reshape(-1, 50), torch.tensor([-1]).cuda())
cosine_similarity_s_c_v = self.cosine(output['s_v'].reshape(-1, 50), output['c_v'].reshape(-1, 50), torch.tensor([-1]).cuda())
cosine_similarity_s_c_a = self.cosine(output['s_a'].reshape(-1, 50), output['c_a'].reshape(-1, 50), torch.tensor([-1]).cuda())

Hey, Is your solution to do cosine similarity on word Embeddings? If my code looks like this, is cosine similarity calculated at the sentence level?

                    cosine_similarity_s_c_l = self.cosine(output['s_l'].permute(1,0,2).contiguous().view(output['s_l'].size(1), -1),
                                                          output['c_l'].permute(1,0,2).contiguous().view(output['c_l'].size(1), -1),
                                                          torch.tensor([-1]).cuda()).mean(0)
