AutoForwardDiff() Error no method matching

General Usage

Hi, I am trying to replicate the main examples for the Optimization package

https://docs.sciml.ai/Optimization/stable/getting_started/

However, when I try using the automatic differentiation Optimization.AutoForwardDiff() I get an error. Next the code I am using

using Optimization
rosenbrock(u, p) = (p[1] - u[1])^2 + p[2] * (u[2] - u[1]^2)^2
u0 = zeros(2)
p = [1.0, 100.0]
using OptimizationOptimJL
using OptimizationBBO
using ForwardDiff
optf = OptimizationFunction(rosenbrock, Optimization.AutoForwardDiff())

The last line gives the following error

ERROR: MethodError: no method matching (OptimizationFunction{true})(::typeof(rosenbrock), ::AutoForwardDiff{nothing, Nothing})
Closest candidates are:
(OptimizationFunction{iip})(::Any) where iip at ~/.julia/packages/SciMLBase/QqtZA/src/scimlfunctions.jl:3583

Are you on the latest version? Julia v1.9? This seems to run fine:

using Optimization
rosenbrock(u, p) = (p[1] - u[1])^2 + p[2] * (u[2] - u[1]^2)^2
u0 = zeros(2)
p = [1.0, 100.0]
using ForwardDiff
optf = OptimizationFunction(rosenbrock, Optimization.AutoForwardDiff())

I copied and pasted the code that was posted, I do not have an error.

4

I have just updated to v.1.9 but I am still getting the same error.

5

Have you updated all of the packages and rerun the code? You can do so by entering the Pkg REPL by pressing ] and type “update” in the REPL without the “” symbol.

6

Done, same error.

7

Can you share ]st?

SciMLBase is in the stone age. Maybe Try ]add SciMLBase@1.97 and see what it says. And try it in a new REPL session.

It now works, thanks!

No problem. Yeah the ^ means an old package version, and usually if you’re having an issue that’s the first thing to check. The documentation always defaults to displaying the newest version, so if you’re on an older version you need to look for the older version of some documentation and… nobody does that :sweat_smile:. So most weird issues tend to just be from accidentally being on an older version for some reason or another.
