Error message related with sub-process of optimizer

[annsonic]

Dear HPOlib team,

Thanks for providing such useful tool!
But I am confused why I always get error messages in certain system call sub-process, even when I just test on the default benchmark - branin.
The optimization result seems working.
Should I ignore these error messages? Or do you have other solutions?
Thank you very much.

• My system is Ubuntu 14.04.

• HPOlib is installed by following "Installing inside an virtualenv" instruction.

• for TPE(hyperopt_august2013_mod) sampled error message:

Dear annsonic, Great to hear that you find HPOlib useful. Indeed, these error messages aren't real errors. They are rather logs of what's happening in the optimization procedure. As long as the optimization results are fine in the end, you can simply ignore them. Best, Matthias
