About graph_pair_sim function

[zzh-ecnu]

Hello~An excellent work!

When reading your code, i find that the implement of function "graph_pair_sim" is different from loss.py and match_fn.py

Code in match_fn.py

dis_loc = (loc_dis_mat * weight_mat).mean()

Code in loss.py

dis_loc = (loc_dis_mat * weight_mat).sum()

I think cause goal of script is different, so when matching it is mean(), and when calculating loss it is sum(), all right？
