[Discussion] How to set GPU device

I have multiple GPU's but I can't figure out how to set which GPU device separator should use.

In my python script I've tried adding `os.environ['CUDA_VISIBLE_DEVICES'] = "1"` but it does nothing.

I've also tried adding `device_count={'GPU': 1}` to `ConfigProto`, but it does nothing either.

Has anyone got a clue how to set which device to use?

I'm on Windows 10 with RTX2080
