Hello Everyone, I have been trying to rerun the Lotka_voltera code on the blog: DiffEqFlux.jl – A Julia Library for Neural Differential Equations , but for some reason i never get it running no matter how i tried. Can some please help me. Thank you

I just ran all of the code in the blog in order. It seemed to work just fine. The code that I ran was: using DifferentialEquations function lotka_volterra(du,u,p,t) x, y = u α, β, δ, γ = p du[1] = dx = α*x - β*x*y du[2] = dy = -δ*y + γ*x*y end u0 = [1.0,1.0] tspan = (0.0,10.0) p = [1.5,1.0,…

Hi Miraj, welcome to the community. Please read: make it easier to help you .

What did you run? On what version of Julia? With what packages? What error did you get?

There is nothing wrong with my question. If you cannot help, you also don’t have to flag my questions.

It looks like you posted it in the wrong thread, which is why no one here saw that there was a response and thus we couldn’t help you. Let me copy it over to here: Hello ChrisRackauckas, Thank you very much for coming to my rescue: This is exactly where my problems start: cb() Flux.train!(loss…

From that post, you can see that the issue is init(::Vector{Float64}, ::ODEProblem: there is no dispatch of init where the first thing is a Vector{Float64}. All calls of init always start with the ODEProblem. This is not something seen in the original code. In order to help you debug this, we’ll nee…

Thank you very much Chris Rackauckas. I really appreciate your help. I don’t know what actually happened, but for some reason everything is now working without any errors. Thanks
