I am trying to run the example of PINN soling PDE( https://github.com/SciML/NeuralPDE.jl )
But when I use the:
discretization = PhysicsInformedNN(chain, QuadratureTraining(),init_params =initθ)
in later part of:
it is having some error here.
But if I change the training strategy to GridTraining:
discretization = PhysicsInformedNN(chain, GridTraining(dx),init_params =initθ)
That error part is solved.
I am confused since the datatype of this : prob = discretize(pde_system,discretization)
is always OptimizationProblem for both training strategy why I cannot use the QuadratureTraining here
