Context objects

When you are developing a model in pytorch, you often want to be able to train the model in many different settings, such as multi-node distributed, single gpu or even just on the cpu depending on your work location and on available resources. The main purpose of the context object is to allow you to transition seamlessly between these different modes of training, without changing your code.

If you are familiar with the torch.nn.Module object, you know that whenever you add a paramater to the object, it gets registered with it, and when you want to move the model to another device, you simply call module.cuda() or module.cpu() to move all paramters registered with the module.

A context object is like a torch module on steroids. You are meant to register every object important to your training session with it, e.g. models, optimizers, epoch counter etc. This also gives the benefit of easily saving and restoring the state of your session.
