XJDKC commented on issue #674: Autograd Layer constructor
   > > I think it's not an issue. When we use the computational graph, initialization
operations won't be buffered since we just need to execute them once. For these operations,
I just execute them immediately instead of buffering them into the graph at present. So before
running the entire graph, all parameter tensors will be initialized.

is for initialization or not?
   At present, if the operations are for initialization, they are likely to be in the constructor
function. So I just turn on the graph before calling the \_\_call\_\_ function of Layer and
forward and backward function of Operation. So all the initialization operations in the constructor
will be executed immediately. For those initialization operations in the functions I mentioned
above, I turn off the buffer before calling them. Like this, [turn off graph](
