Which modulus version should we use to run oour cases. I see that modulus-sym has the example cases and have been using that. For future cases we develop, should we use modulus or modulus-sym?
The goal of Modulus and Modulus-Sym are slightly different. Don’t think of these as versions, but rather different components / libraries of Modulus. Modulus (Core) is a more PyTorch developer orientated tool kit while Modulus-Sym provides an abstract framework with the symbolic loss representation. I.e. Are you interested in PINNs? Use Modulus-Sym. Are you a PyTorch developer looking at general Physics-ML, use Modulus (Core). Some discussion in our migration guide.
Secondly, once a model is trained, how do we use it for a live example? or deploy it for our purposes?
