Optimization

[clarazen]

Hello,

When running the test example (copy paste from the documentation) and trying to optimize the hyperparameters I get the error as in the figure attached. Is there a problem with Optim or with this package?

Thanks you,
I appreciate the help.

Hi @clarazen. It looks like the syntax on the Optim package has changed. For the moment, removing method=ConjugateGradient will revert the optimizer back to its default algorithm, i.e. just using optimize!(gp) should work. I'll take a closer look at this and try to align our syntax with that of the Optim package.

Thanks Chris, indeed without specifying the method it works.

Hi @clarazen. I've fixed the issue now and tagged a new version of the package. If you reinstall the package the optimize! function should work fine now with any of the Optim methods.
