   > > > @billishyahao I remember that you introduced a mechanism to query 
optimal layout and alter op layout before the graph is consumed by DNNL, just 
like we do for `Conv`. Did you cancel that and do the layout transform in dnnl 
json runtime? If so, I agree with @apeskov and wondering why no layout 
transform of the weights.

the weights in build time to ensure optimal performance in run time.
