I am happy to accept a PR, but I would just make a separate branch in the if
for the case numfg>10
and print out a warning indeed.
from optimkit.jl.
Hi, it seems I have exactly the same issue and in my case it would be useful if the optimizer returned something (e.g., just an initial guess x_0). Is there some simple way to force it to stop bisecting after a few attempts and give up (just returning an initial condition)?
Thank you.

I will try to look at this soon; the linesearch logic should be changed somewhat to allow for a graceful return indeed.

out of curiosity, is there a small minimal example somewhere of bisect looping?
from optimkit.jl.
Oh, I am afraid not really right now. I am developing an MPS-like architecture for image classification and when I optimize MPS tensors one by one, sometimes optimizations just gets stuck on some tensor and does not proceed to the next tensors.

Hi, if I just download OptimKit.jl and then add this condition numfg>10
as suggested by @marius311, could you please suggest how I then can use it? If I just include a line include("../../OptimKit/src/OptimKit.jl")
, I then get an error UndefVarError: ConjugateGradient not defined
. But if I also add another line include("../../OptimKit/src/gd.jl")
, I get another error LoadError: UndefVarError: AbstractLineSearch not defined
. Finally, if I include the following lines
using Printf
include("../../OptimKit/src/OptimKit.jl")
include("../../OptimKit/src/linesearches.jl")
include("../../OptimKit/src/gd.jl")
I get this error: LoadError: UndefVarError: OptimizationAlgorithm not defined
(and I always get WARNING: replacing module OptimKit
, even though I ran Pkg.rm("OptimKit.jl)
before).
Thank you.

One hack is just to do
using OptimKit
@eval OptimKit function bisect(iter::HagerZhangLineSearchIterator, a::LineSearchPoint, b::LineSearchPoint)
# modified body here...
end
Another is you could pkg> dev --local OptimKit
and edit the files directly.
from optimkit.jl.
Thank you @marius311! I use the first approach (with @eval). Sorry for my ignorance, but how should I proceed with the second approach? I mean, I execute pkg> dev --local OptimKit
, but what's next? One part of an output of the previous command is OptimKit v0.3.1 ⇒ v0.3.2 dev/OptimKit
, but when I cd
to \dev
, I cannot find OptimKit
there.
Thank you!
