Error when trying to do 'Hyperparameter Optimization' using Parallel Computing

Hello,

I am trying to optimize the function fitrsvm.

But when I set 'true' to the 'UseParallel' property, I am getting a error.

This is the code:

smv_model =  fitrsvm(X,y,...
    'OptimizeHyperparameters','all',...
    'HyperparameterOptimizationOptions',...
    struct('UseParallel',true));

The error message:

Error using classreg.learning.paramoptim.parseFitoptimizingArgs>validateAndCompleteStructFields (line 171)
Unrecoginized field passed in 'HyperparameterOptimizationOptions' struct: UseParallel.

How can I solve this?

Thanks.

Do you have a Parallel Computing Toolbox license? If so, then please tell us what version of MATLAB you are using.

Yes, the version is 2017a.

Sorry, as the Release Notes show, parallel hyperparameter optimization was added to Bayesian optimization in R2017b.
