How to show loss value of the neural network after solving by Neural.NNODE?

I am using NeuralPDE to solve the ODE system. Because the iterations of the network are high (I choose 3000), I set the verbose as false as the following code to cut off the displaying of current loss:

chain = Flux.Chain(Flux.Dense(1, 6, tanh),Flux.Dense(6, 2))
opt = OptimizationOptimisers.Adam(0.03)
sol = solve(prob, NeuralPDE.NNODE(chain, opt), verbose=false, abstol=1f-6, maxiters=3000)

In my case how could I access the loss of the network after solving it?
Thank you all.
