Consider the following Java program. Im extending a complex model (already with DistributedDataParallel with find_unused_parameters set to True) in PyTorch on detectron2.. Ive added a new layer generating some additional output to the original network - initially, that layer was frozen (requires_grad = False) and everything was working fine.I later decided to unfreeze this layer. In other words you can say that only a single copy of static variable is created and shared among all the instances of the class.
