I am using DifferentialEquations.jl in a Julia Notebook. The code starts as: using DifferentalEquations using ParameterizedFunctions sir_ode = @ode_def SIRModel begin dS = -β*S*I dI = β*S*I-γ*I dR = γ*I end β γ When executed, I get the error: UndefVarError: @ode_def not defin…

@ode_def not defined

Did your packages update mid-notebook? If you do that, you need a new Julia session to use the newer versions, so it could be something like that?
