I tried to solve the ODE problem by PDESystem on NeuralPDE with relu as activation functions. chain =[Lux.Chain(Dense(1,10,Lux.relu),Dense(10,20,Lux.relu),Dense(20,10,Lux.relu),Dense(10,1)) for _ in 1:12] @named pde_system = PDESystem(eqs,bcs,domains,[t],dvs) strategy = NeuralPDE.GridTraining(0.0…

What exactly is the issue? It looks like the code that you posted runs fine. [Screenshot 2023-08-06 044445] Did you run it in a fresh REPL? It’s giving you a warning that sin is redefined which means that there’s something that you did in your script that’s not in your MWE.
