Thanks for letting me know. I'll take a look. In the meantime, you can also use 'spearmint' in the bin subdirectory https://github.com/JasperSnoek/spearmint/blob/master/spearmint/bin/spearmint. e.g. navigate to the bin subdirectory and type:...

Yeah, that's the right thing to do. This will happen occasionally if the code is killed when the file lock is being held. Maybe I should add a message somewhere...

Interesting.... Do you mean by 'examples' the number of evaluations that spearmint has observed or some quantity that pertains to your code that spearmint is calling? Certainly the noise will...

Yes, this is normalized. All dimensions are projected to the unit interval [0,1] and then the GP is fit in that space. So a length scale of 1.36 means that...

Aha, is it possible that your code is returning NaNs or infs? This error basically means that the sampling algorithm is not finding any reasonably valid setting for the hyperparameters...

Ah, so there are solutions that will be rolled out hopefully very shortly, depending on the cause of this. One potential cause is that there are invalid values being thrown...

Hi Alex, that's certainly a use case that we hadn't anticipated. Yes, the chooser saves its state at each iteration and then continues sampling by 'hot starting' from the state...
