Hi,
I am trying to execute the foloowing statment "$ python demo.py --prefix final --epoch 0 --image myimage.jpg --gpu 0"

The demo.py file is at example/rcnn

Error Message:

I want to to execute on a CPU as I am not sure My graphics card supports Cuda or not

Environment info

Operating System:
Mac OS sierra 10.12.1
my graphics card is Intel Iris Pro 1536 MB

Package used (Python):

@piiswrong
python demo.py --prefix final --epoch 0 --image myimage.jpg

caused same error:-

mxnet.base.MXNetError: [17:01:52] src/ndarray/ndarray.cc:296: GPU is not enabled

[piiswrong]

if __name__ == '__main__':
args = parse_args()
ctx = mx.gpu(args.gpu_id)

in demo.py replace mx.gpu(args.gpu_id) with mx.cpu(0)

It is still not working.
I got the following message
"
An fatal error occurred in asynchronous engine operation. If you do not know what caused this error, you can try set environment variable MXNET_ENGINE_TYPE to NaiveEngine and run with debugger (i.e. gdb). This will force all operations to be synchronous and backtrace will give you the series of calls that lead to this error. Remember to set MXNET_ENGINE_TYPE back to empty after debugging.
