Is there a way of not showing the time spent in each iteration in Optim.jl while using the option show_trace=true? The current output is as follows: [Screen Shot 2021-02-14 at 11.00.18 AM] I just want the lines with “time” not to be shown. I currently use: res = optimize(p->objectivefunc!(p,fp…

You can pass a “callback” fonction that will be called at each iteration, I think you’ll have access to more things in there, see this example : Optim.jl Pure Julia implementations of optimization algorithms.

You can just put print statements in your objective function (or a wrapper thereof) and print out whatever information you want, including timing.

Thanks! I’ll try this. When I used showing trace a couple of months ago, the output was similar to the one shown here: Optim.jl Pure Julia implementations of optimization algorithms. Do you know why it changed to include the cumulative time spent after eac…

Some people asked for for it and I figured it was a fair request. Ideologically I agree with @stevengj that it’s probably easier to just @info from your objective function code. julia> using Optim julia> function rosenbrock(x) fx = (1.0 - x[1])^2 + 100.0 * (x[2] - x[1]^2)^2 @…

Sure, but then if there are 100 function evaluations in one iteration, you print this output 100 times instead of just once (or once every nth iteration) as in the show_trace output. It would have been great if printing out the cumulative time was an option we can turn on or off (though I understan…

Would it be better if it was just one line?
