[SciPy-User] optimize.fmin_cobyla giving nan to objective function

I am using the Gaussian Process module in scikit-learn. It uses
optimize.fmin_cobyla to find the best hyper-parameters. It looks like,
though, that fmin_cobyla is, after a couple of iterations, feeding nan to
the objective function. Any ideas?

scipy.__version__ = '0.10.0.dev7180'
