Skip Connection for RGCN

Dear author, I want to add skip connections for rgcn, because i find the implementation in DGL is very likely to meet over smoothing problem, which means all the embeddings of entities are the same and very small, the loss is always 0.6931(I think it is also the reason to cause the problem on github:
Can you please give me some help to let me know how to add skip connections for your RGCN codes, any advices can help a lot ! Thanks very much!!!

Hi @Lee-zix,

The code already has loop messages implemented (see here). I think you can change it to be skip connections.
