How to handle gpu

[emanjavacas]

We should pass params to the model defining whether to use gpu and which gpu to use.

Could we have by default some kind of autodetect ? This would make sense for the CLI at least.

Sure, it could be part of the model interface, since this is framework dependent.

I might have an issue with GPU actually :

Traceback (most recent call last):

    load_entry_point('pandora', 'console_scripts', 'pandora-train')()

when setting gpu to True

I haven't tested on the GPU yet. I will work on that and hopefully we will have a way to do GPU detection for the interface
