GPU scaling

[petergerten]

Is there any way to train with multiple GPUs?
The current scripts seem to only utilize the first GPU, altough TF 'sees' all of them.

Unfortunately, I haven't yet played with the multi-tower training stuff as I only have a humble little 970 at the moment. Pull requests are welcomed!

ok, thanks. I am quite new to TF though - will take a look.

I'll leave this issue open in case someone implemented it in one of their forks and sees this.
