I am an absolute beginner to Julia trying to get started with the first NeuralPDE.jl tutorial at: https://neuralpde.sciml.ai/dev/examples/ode/
I am using Julia 1.5.2 and understand that I need to install some packages before I can get started with the tutorial. But I am not clear as to what exactly as I don’t see specific documentation about that. [1]
What I have tried so far is to get into pkg mode and run the following:
add DifferentialEquations
add Flux
add Optim
add NeuralPDE
But when I then try to follow the run the tutorial’s first lines, I stumble into the following:

Could someone point me to what I should be trying to do to correct this? I imagine I should be uninstalling/reinstalling different variants of these requirements, or maybe an additional package DiffEqBase(?), but I am not sure.
[1] I will independently write on GitHub and see if the authors are interested in additions to the documentation that help beginners like me.
