piiswrong commented on issue #10354: Expose the number of GPUs.
URL: https://github.com/apache/incubator-mxnet/pull/10354#issuecomment-382822518
So the current issue is if mxnet is compiled with GPU but run on gpu-less
machine, cudaGetDeviceCount will return 30 instead of cudaErrorNoDevice?
Any idea why this happens? If we can't fix this I think its good enough to
raise an error saying "failed getting number of gpus"
