ValueError by passing an int instead of a float about smt HOT 3 CLOSED

FYI, actually RBF is written in C++ and cythonized which explains the "weird" error message.

Hi Matthias. I would say it is normal. Historically, SMT only handles numpy arrays of floats.

Hi Rémi,
Thanks for your quick reply.
The error message surprised me a little and the notion of buffer was not obvious (I was expecting to read input value or something like that). I'm creating a wrapper of SurrogateModel and I think I will force the conversion to float to avoid any problems.
As it is the expected SMT behavior, I close this issue.
