Shortcut for enabling GPU


Hi, there. Does mxnet have a command line option for enabling GPU?
In Tensorflow, I can use export CUDA_VISIBLE_DEVICES. In DyNet, I can use --dynet-gpus cli option.
In mxnet, do I have to implement such switches by myself?


Default datatype

@hankcs do you mean for disabling GPUs?
all available GPUs are activated by default with MXNet.


Wow, that’s convenient. I mean enabling, sometimes I develop models on mac and run it on server, so it’s convenient to active GPU by default.
