FAQ

Optimization termination

My optimization run terminates early!

• Try increasing the initial_design_numdata parameter.
• You can try setting eps to 0 - but in general, duplicate suggestions are rare.

Accessing model contents

How do I access the raw data in the model?

• bo.X and bo.Y store the np.ndarrays containing the regression data used to fit the model.

Plotting

My plot shows weird Y values!

• Your Y data is being normalized by default. See e.g. this issue. Try bo=BayesianOptimization(..., normalize_Y=False).

Objective function

Can I pass some arguments to the objective that are irrelenvant to the optimization?

• GPyOpt does not support this natively, but here is a nice way of doing it from @alexmaraval: https://github.com/SheffieldML/GPyOpt/issues/318
