above todo is critical when guaranteeing serialized weight layout, without those kind of deterministic assumption, we cannot load weight outside context of layer.

eg) fully connected layer has weight - maps to a, bias - maps to b When we load the weight from different place, the layer weights will maps to weight - a', bias - b'. we have to guarantee a == a', b == b'. If this indexes are determined per run, we cannot never make such assumption.

The implementation implemented in a way it is deterministic. We just have to make it as the api behavior :)
