Is weight initialization neccessary ??

[Johnson-yue]

Hi, in four experiments model.py

colorization_cINN

no weight initialization and only use load pretrained model (what is load pretrained weight?) , use FrEIA API is version==0.2

colorization_minimal_example

no weight initialization , use FrEIA API is version==0.1

mnist_cINN

using normal distribution initialize weight , use FrEIA API is version==0.1

mnist_minimal_example

no weight initialization and use FrEIA API is version==0.1

I don't know if you have time to unify the usage ？？
